The TotalStorage Productivity Center is based on the recent standard issued by the Storage Networking Industry Association (SNIA). The standard addresses the interoperability of storage hardware and software within a SAN.1.1.1 Standards organizations and standards Today, there are at least 10 organizations involved in creating standards for storage, storage management, SAN management, and interoperability. Figure 1-1 shows the key organizations involved in developing and promoting standards relating to storage, storage management, and SAN management, and the relevant standards for which they are responsible. Figure 1-1 SAN management standards bodies Key standards for Storage Management are: Distributed Management Task Force (DMTF) Common Information Model (CIM) Standards. This includes the CIM Device Model for Storage, which at the time of writing was Version 2.7.2 for the CIM schema. Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S).2 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  18. 18. 1.2 IBM TotalStorage Open Software family The IBM TotalStorage Open Software Family, is designed to provide a full range of capabilities, including storage infrastructure management, Hierarchical Storage Management (HSM), archive management, and recovery management. The On Demand storage environment is shown in Figure 1-2. The hardware infrastructure is a complete range of IBM storage hardware and devices providing flexibility in choice of service quality and cost structure. On top of the hardware infrastructure is the virtualization layer. The storage virtualization is infrastructure software designed to pool storage assets, enabling optimized use of storage assets across the enterprise and the ability to modify the storage infrastructure with minimal or no disruption to application services. The next layer is composed of storage infrastructure management to help enterprises understand and proactively manage their storage infrastructure in the on demand world; hierarchical storage management to help control growth; archive management to manage cost of storing huge quantities of data; recovery management to ensure recoverability of data. The top layer is storage orchestration which automates work flows to help eliminate human error. Figure 1-2 Enabling customer to move toward On Demand Previously we discussed the next steps or entry points into an On Demand environment. The IBM software products which represent these entry points and which comprise the IBM TotalStorage Open Software Family is shown in Figure 1-3 on page 4. Chapter 1.

  20. 20. Figure 1-4 Centralized, automated storage infrastructure management1.3.1 Data subject matter expert: TotalStorage Productivity Center for Data The Data subject matter expert has intimate knowledge of how storage is used, for example whether the data is used by a file system or a database application. Figure 1-5 on page 6 shows the role of the Data subject matter expert which is filled by the TotalStorage Productivity Center for Data (formerly the IBM Tivoli Storage Resource Manager). Chapter 1. IBM TotalStorage Productivity Center overview 5
  21. 21. Figure 1-5 Monitor and Configure the Storage Infrastructure Data area Heterogeneous storage infrastructures, driven by growth in file and database data, consume increasing amounts of administrative time, as well as actual hardware resources. IT managers need ways to make their administrators more efficient and more efficiently utilize their storage resources. Tivoli Storage Resource Manager gives storage administrators the automated tools they need to manage their storage resources more cost-effectively. TotalStorage Productivity Center for Data allows you to identify different classes of data, report how much space is being consumed by these different classes, and take appropriate actions to keep the data under control. Features of the TotalStorage Productivity Center for Data are: Automated identification of the storage resources in an infrastructure and analysis of how effectively those resources are being used. File-system and file-level evaluation uncovers categories of files that, if deleted or archived, can potentially represent significant reductions in the amount of data that must be stored, backed up and managed. Automated control through policies that are customizable with actions that can include centralized alerting, distributed responsibility and fully automated response. Predict future growth and future at-risk conditions with historical information. Through monitoring and reporting, TotalStorage Productivity Center for Data helps the storage administrator prevent outages in the storage infrastructure. Armed with timely information, the storage administrator can take action to keep storage and data available to the application. TotalStorage Productivity Center for Data also helps to make the most efficient use of storage budgets, by allowing administrators to use their existing storage more efficiently, and more accurately predict future storage growth.6 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  22. 22. TotalStorage Productivity Center for Data monitors storage assets, capacity, and usage across an enterprise. TotalStorage Productivity Center for Data can look at: Storage from a host perspective: Manage all the host-attached storage, capacity and consumption attributed to file systems, users, directories, and files Storage from an application perspective: Monitor and manage the storage activity inside different database entities including instance, tablespace, and table Storage utilization and provide chargeback information. Architecture The TotalStorage Productivity Center for Data server system manages a number of Agents, which can be servers with storage attached, NAS systems, or database application servers. Information is collected from the Agents and stored in a database repository. The stored information can then be displayed from a native GUI client or browser interface anywhere in the network. The GUI or browser interface gives access to the other functions of TotalStorage Productivity Center for Data, including creating and customizing of a large number of different types of reports and setting up alerts. With TotalStorage Productivity Center for Data, you can: Monitor virtually any host Monitor local, SAN-attached and Network Attached Storage from a browser anywhere on the network For more information refer to the redbook IBM Tivoli Storage Resource Manager: A Practical Introduction, SG24-6886.1.3.2 Fabric subject matter expert: Productivity Center for Fabric The storage infrastructure management for Fabric covers the Storage Area Network (SAN). To handle and manage SAN events you need a comprehensive tool. The tool must have a single point of operation and it tool must be able to perform all the tasks from the SAN. This role is filled by the TotalStorage Productivity Center for Fabric (formerly the IBM Tivoli SAN Manager) which is a part of the IBM TotalStorage Productivity Center. The Fabric subject matter expert is the expert in the SAN. Its role is: Discovery of fabric information Provide the ability to specify fabric policies – What HBAs to use for each host and for what purpose – Objectives for zone configuration (for example, shielding host HBAs from one another and performance) Automatically modify the zone configuration TotalStorage Productivity Center for Fabric provides real-time visual monitoring of SANs, including heterogeneous switch support, and is a central point of control for SAN configuration (including zoning). It automates the management of heterogeneous storage area networks, resulting in” Improved Application Availability – Predicting storage network failures before they happen enabling preventative maintenance – Accelerate problem isolation when failures do happen Chapter 1.

  24. 24. TotalStorage Productivity Center for Fabric componentsThe major components of the TotalStorage Productivity Center for Fabric include: A manager or server, running on a SAN managing server Agents, running on one or more managed hosts Management console, which is by default on the Manager system, plus optional additional remote consoles Outband agents - consisting of vendor-supplied MIBs for SNMPThere are two additional components which are not included in the TotalStorage ProductivityCenter. IBM Tivoli Enterprise™ Console (TEC) which is used to receive TotalStorage Productivity Center for Fabric generated events. Once forwarded to TEC, These can then be consolidated with events from other applications and acted on according to enterprise policy. IBM Tivoli Enterprise Data Warehouse (TEDW) is used to collect and analyze data gathered by the TotalStorage Productivity Center for Fabric. The Tivoli Data Enterprise Warehouse collects, organizes, and makes data available for the purpose of analysis in order to give management the ability to access and analyze information about its business.The TotalStorage Productivity Center for Fabric functions are distributed across the Managerand the Agent.TotalStorage Productivity Center for FabricServer Performs initial discovery of environment: – Gathers and correlates data from agents on managed hosts – Gathers data from SNMP (outband) agents – Graphically displays SAN topology and attributes Provides customized monitoring and reporting through NetView® Reacts to operational events by changing its display (Optionally) forwards events to Tivoli Enterprise Console® or SNMP managersTotalStorage Productivity Center for Fabric AgentGathers information about: SANs by querying switches and devices for attribute and topology information Host-level storage, such as file systems and LUNs Event and other information detected by HBAs Forwards topology and event information to the ManagerDiscover SAN components and devicesTotalStorage Productivity Center for Fabric uses two methods to discover information aboutthe SAN - outband discovery, and inband discovery.Outband discovery is the process of discovering SAN information, including topology anddevice data, without using the Fibre Channel data paths. Outband discovery uses SNMPqueries, invoked over IP network. Outband management and discovery is normally used tomanage devices such as switches and hubs which support SNMP. Chapter 1. IBM TotalStorage Productivity Center overview 9
  25. 25. In outband discovery, all communications occur over the IP network: TotalStorage Productivity Center for Fabric requests information over the IP network from a switch using SNMP queries on the device. The device returns the information toTotalStorage Productivity Center for Fabric, also over the IP network. Inband discovery is the process of discovering information about the SAN, including topology and attribute data, through the Fibre Channel data paths. In inband discovery, both the IP and Fibre Channel networks are used: TotalStorage Productivity Center for Fabric requests information (via the IP network) from a Tivoli SAN Manager agent installed on a Managed Host. That agent requests information over the Fibre Channel network from fabric elements and end points in the Fibre Channel network. The agent returns the information to TotalStorage Productivity Center for Fabric over the IP network. TotalStorage Productivity Center for Fabric collects, co-relates and displays information from all devices in the storage network, using both the IP network and the Fibre Channel network. If the Fibre Channel network is unavailable for any reason, monitoring can still continue over the IP network. TotalStorage Productivity Center for Fabric benefits TotalStorage Productivity Center for Fabric discovers the SAN infrastructure, and monitors the status of all the discovered components. Through Tivoli NetView, the administrator can provide reports on faults on components (either individually or in groups, or “smartsets”, of components). This will help them increase data availability for applications so the company can either be more efficient, or maximize the opportunity to produce revenue. TotalStorage Productivity Center for Fabric helps the storage administrator: Prevent faults in the SAN infrastructure through reporting and proactive maintenance, and Identify and resolve problems in the storage infrastructure quickly, when a problem Supported devices for TotalStorage Productivity Center for Fabric Provide fault isolation of SAN links. For more information about the TotalStorage Productivity Center for Fabric, refer to IBM Tivoli Storage Area Network Manager: A Practical Introduction, SG24-6848.1.3.3 Disk subject matter expert: TotalStorage Productivity Center for Disk The Disk subject matter expert’s job allows you to manage the disk systems. It will discover and classify all disk systems that exist and draw a picture of all discovered disk systems. The Disk subject matter expert provides the ability to monitor, configure, create disks and do LUN masking of disks. It also does performance trending and performance threshold I/O analysis for both real disks and virtual disks. It also does automated status and problem alerts via SNMP. This role is filled by the TotalStorage Productivity Center for Disk (formerly the IBM TotalStorage Multiple Device Manager Performance Manager component). The requirements addressed by the Disk subject matter expert are shown in Figure 1-7 on page 11. The disk systems monitoring and configuration needs must be covered by a comprehensive management tool like the TotalStorage Productivity Center for Disk.10 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  26. 26. Figure 1-7 Monitor and configure the Storage Infrastructure Disk areaThe TotalStorage Productivity Center for Disk provides the raw capabilities of initiating andscheduling performance data collection on the supported devices, of storing the receivedperformance statistics into database tables for later use, and of analyzing the stored data andgenerating reports for various metrics of the monitored devices. In conjunction with datacollection, the TotalStorage Productivity Center for Disk is responsible for managing andmonitoring the performance of the supported storage devices. This includes the ability toconfigure performance thresholds for the devices based on performance metrics, thegeneration of alerts when these thresholds are exceeded, the collection and maintenance ofhistorical performance data, and the creation of gauges, or performance reports, for thevarious metrics to display the collected historical data to the end user. The TotalStorageProductivity Center for Disk enables you to perform sophisticated performance analysis forthe supported storage devices.FunctionsTotalStorage Productivity Center for Disk provides the following functions: Collect data from devices The Productivity Center for Disk collects data from the IBM TotalStorage Enterprise Storage Server (ESS), SAN Volume Controller (SVC), DS400 family and SMI-S enabled devices. Each Performance Collector collects performance data from one or more storage groups, all of the same device type (for example, ESS or SAN Volume Controller). Each Performance Collection has a start time, a stop time, and a sampling frequency. The performance sample data is stored in DB2® database tables. Configure performance thresholds You can use the Productivity Center for Disk to set performance thresholds for each device type. Setting thresholds for certain criteria enables Productivity Center for Disk to notify you when a certain threshold has been exceeded, so that you to take action before a critical event occurs. Chapter 1. IBM TotalStorage Productivity Center overview 11
  27. 27. You can specify what action should be taken when a threshold-exceeded condition occurs. The action may be to log the occurrence or to trigger an event. The threshold settings can vary by individual device. Monitor performance metrics across storage subsystems from a single console Receive timely alerts to enable event action based on customer policies View performance data from the Productivity Center for Disk database You can view performance data from the Productivity Center for Disk database in both graphical and tabular forms. The Productivity Center for Disk allows a TotalStorage Productivity Center user to access recent performance data in terms of a series of values of one or more metrics, associated with a finite set of components per device. Only recent performance data is available for gauges. Data that has been purged from the database cannot be viewed. You can define one or more gauges by selecting certain gauge properties and saving them for later referral. Each gauge is identified through a user-specified name, and once defined, a gauge can be "started", which means it is then displayed in a separate window of the TotalStorage Productivity Center GUI. You can have multiple gauges active at the same time. Gauge definition will be accomplished through a wizard, to aid in entering a valid set of gauge properties. Gauges are saved in the Productivity Center for Disk database and retrieved upon request. When you request data pertaining to a defined gauge, the Performance Manager builds a query to the database, retrieves and formats the data and returns it to you. Once started, a gauge is displayed in its own window, and displays all available performance data for the specified initial date/time range. The date/time range can be changed after the initial gauge widow is displayed. Focus on storage optimization through identification of best LUN The Volume Performance Advisor is an automated tool to help the storage administrator pick the best possible placement of a new LUN to be allocated, that is, the best placement from a performance perspective. It also uses the historical performance statistics collected from the supported devices, to locate unused storage capacity on the SAN that exhibits the best (estimated) performance characteristics. Allocation optimization involves several variables which are user controlled, such as required performance level and the time of day/week/month of prevalent access. This function is fully integrated with the Device Manager function, this is so that when a new LUN is added, for example, to the ESS, the Performance Manager can seamlessly select the best possible LUN. For detailed information about how to use the functions of the TotalStorage Productivity Center for Disk refer to Chapter 6, “TotalStorage Productivity Center for Disk use” on page 227.1.3.4 Replication subject matter expert: Productivity Center for Replication The Replication subject matter expert’s job is to provide a single point of control for all replication activities. This role is filled by the TotalStorage Productivity Center for Replication. Given a set of source volumes to be replicated, the Productivity Center for Replication will find the appropriate targets, perform all the configuration actions required, and ensure the source and target volumes relationships are set up. Given a set of source volumes that represent an application, the Productivity Center for Replication will group these in a consistency group, give that consistency group a name, and allow you to start replication on the application. Productivity Center for Replication will start up all replication pairs and monitor them to completion. If any of the replication pairs fail, meaning the application is out of sync, the Productivity Center for Replication will suspend them until the problem is resolved, resync12 Managing Disk Subsystems using IBM TotalStorage Productivity Center

The Productivity Center for Replication provides completemanagement of the replication process.The requirements addressed by the Replication subject matter expert are shown Figure 1-8.Replication in a complex environment needs to be addressed by a comprehensivemanagement tool like the TotalStorage Productivity Center for Replication.Figure 1-8 Monitor and Configure the Storage Infrastructure Replication areaFunctionsData replication is the core function required for data protection and disaster recovery. Itprovides advanced copy services functions for supported storage subsystems on the SAN.Replication Manager administers and configures the copy services functions and monitorsthe replication actions. Its capabilities consist of the management of two types of copyservices: the Continuous Copy (also known as Peer-to-Peer, PPRC, or Remote Copy), andthe Point-in-Time Copy (also known as FlashCopy®). At this time TotalStorage ProductivityCenter for Replication supports the IBM TotalStorage ESS.Productivity Center for Replication includes support for replica sessions, which ensures thatdata on multiple related heterogeneous volumes is kept consistent, provided that theunderlying hardware supports the necessary primitive operations. Productivity Center forReplication also supports the session concept, such that multiple pairs are handled as aconsistent unit, and that Freeze-and-Go functions can be performed when errors in mirroringoccur. Productivity Center for Replication is designed to control and monitor the copy servicesoperations in large-scale customer environments.Productivity Center for Replication provides a user interface for creating, maintaining, andusing volume groups and for scheduling copy tasks. The User Interface populates lists ofvolumes using the Device Manager interface. Some of the tasks you can perform withProductivity Center for Replication are: Chapter 1. IBM TotalStorage Productivity Center overview 13
  29. 29. Create a replication group. A replication group is a collection of volumes grouped together so that they can be managed concurrently. Set up a Group for replication. Create, save, and name a replication task. Schedule a replication session with the user interface: – Create Session Wizard. – Select Source Group. – Select Copy Type. – Select Target Pool. – Save Session. Start a replication session A user can also perform these tasks with the Productivity Center for Replication command-line interface. For more information about the Productivity Center for Replication functions refer to Chapter 8, “TotalStorage Productivity Center for Replication use” on page 355.1.4 IBM TotalStorage Productivity Center All the subject matter experts, for Data, Fabric, Disk, and Replication are components of the IBM TotalStorage Productivity Center. The IBM TotalStorage Productivity Center is the first offering to be delivered as part of the IBM TotalStorage Open Software Family. The IBM TotalStorage Productivity Center is an open storage infrastructure management solution designed to help reduce the effort of managing complex storage infrastructures, to help improve storage capacity utilization, and to help improve administrative efficiency. It is designed to enable an agile storage infrastructure that can respond to on demand storage needs. The IBM TotalStorage Productivity Center allows you to manage your storage infrastructure using existing storage management products — Productivity Center for Data, Productivity Center for Fabric, Productivity Center for Disk and Productivity Center for Replication — from one physical place. The IBM TotalStorage Productivity Center components can be launched from the IBM TotalStorage Productivity Center launch pad as shown in Figure 1-9 on page 15.14 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  30. 30. Figure 1-9 IBM TotalStorage Productivity Center Launch Pad The IBM TotalStorage Productivity Center establishes the foundation for IBM’s e-business On Demand technology. We need the function in an On Demand environment to provide IT resources On Demand - when the resources are needed by an application to support the customers business process. Of course, we are able to provide resources or remove resources today but the question is how. The process is expensive and time consuming. The IBM TotalStorage Productivity Center is the basis for the provisioning of storage resources to make the e-business On Demand environment a reality. In the future there will be more automation required to handle the hugh amount work in the provisioning area, more automation like the BM TotalStorage Productivity Center launch pad provides. Automation means workflow. Workflow is the key to getting work automated. IBM has a long history and investment in building workflow engines and work flows. Today IBM is using the IBM Tivoli Intelligent Orchestrator and IBM Tivoli Provisioning Manager to satisfy the resource requests in the e-business on demand™ environment in the server arena. The IBM Tivoli Intelligent Orchestrator and The IBM Tivoli Provisioning Manager provide the provisioning in the e-business On Demand environment.1.4.1 Productivity Center for Disk and Productivity Center for Replication The Productivity Center for Disk and Productivity Center for Replication is software that has been designed to enable administrators to manage SANs and storage from a single console. This software solution is designed specifically for managing networked storage components based on the SMI-S, including: IIBM TotalStorage SAN Volume Controller IBM TotalStorage Enterprise Storage Server (ESS) IBM TotalStorage Fibre Array Storage Technology (FAStT) IBM TotalStorage DS4000 series SMI enabled device Chapter 1. IBM TotalStorage Productivity Center overview 15
  31. 31. Figure 1-10 Managing multiple devices Productivity Center for Disk and Productivity Center for Replication are built on IBM Director, a comprehensive server management solution. Using Director with the multiple device management solution enables administrators to consolidate the administration of IBM storage subsystems and provide advanced storage management functions (including replication and performance management) across multiple IBM storage subsystems. It interoperates with SAN Management and Enterprise System Resource Manager (ESRM) products from IBM, includingTotalStorage Productivity Center for Data and SAN Management products from other vendors. In a SAN environment, multiple devices work together to create a storage solution. The Productivity Center for Disk and Productivity Center for Replication provides integrated administration, optimization, and replication features for interacting SAN devices, including the SAN Volume Controller and DS4000 Family devices. It provides an integrated view of the underlying system so that administrators can drill down through the virtualized layers to easily perform complex configuration tasks and more productively manage the SAN infrastructure. Because the virtualization layers support advanced replication configurations, the Productivity Center for Disk and Productivity Center for Replication products offer features that simplify the configuration, monitoring, and control of disaster recovery and data migration solutions. In addition, specialized performance data collection, analysis, and optimization features are provided. As the SNIA standards mature, the Productivity Center view will be expanded to include CIM-enabled devices from other vendors, in addition to IBM storage. Figure 1-11 on page 17 provides an overview of Productivity Center for Disk and Productivity Center for Replication.16 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  32. 32. IBM TotalStorage Productivity Center Performance Replication Manager Manager Device Manager IBM Director IBM TotalStorage Productivity Center for Fabric WebSphere Application Server DB2Figure 1-11 Productivity Center overviewThe Productivity Center for Disk and Productivity Center for Replication provides support forconfiguration, tuning, and replication of the virtualized SAN. As with the individual devices,the Productivity Center for Disk and Productivity Center for Replication layers are open andcan be accessed via a GUI, CLI, or standards-based Web Services. Productivity Center forDisk and Productivity Center for Replication provide the following functions: Device Manager - Common function provided when you install the base prerequisite products for either Productivity Center for Disk or Productivity Center for Replication Performance Manager - provided by Productivity Center for Disk Replication Manager - provided by Productivity Center for ReplicationDevice ManagerThe Device Manager is responsible for the discovery of supported devices; collecting asset,configuration, and availability data from the supported devices; and providing a limitedtopography view of the storage usage relationships between those devices.The Device Manager builds on the IBM Director discovery infrastructure. Discovery of storagedevices adheres to the SNIA SMI-S specification standards. Device Manager uses theService Level Protocol (SLP) to discover SMI-S enabled devices. The Device Managercreates managed objects to represent these discovered devices. The discovered managedobjects are displayed as individual icons in the Group Contents pane of the IBM DirectorConsole as shown in Figure 1-12 on page 18. Chapter 1. IBM TotalStorage Productivity Center overview 17
  33. 33. Figure 1-12 IBM Director Console Device Manager provides a subset of configuration functions for the managed devices, primarily LUN allocation and assignment. Its function includes certain cross-device configuration, as well as the ability to show and traverse inter-device relationships. These services communicate with the CIM Agents that are associated with the particular devices to perform the required configuration. Devices that are not SMI-S compliant are not supported. The Device Manager also interacts and provides some SAN management functionality when IBM Tivoli SAN Manager is installed. The Device Manager health monitoring keeps you aware of hardware status changes in the discovered storage devices. You can drill down to the status of the hardware device, if applicable. This enables you to understand which components of a device are malfunctioning and causing an error status for the device. SAN Management When a supported SAN Manager is installed and configured, the Device Manager leverages the SAN Manager to provide enhanced function. Along with basic device configuration functions such as LUN creation, allocation, assignment, and deletion for single and multiple devices, basic SAN management functions such as LUN discovery, allocation, and zoning are provided in one step. IBM TotalStorage Productivity Center for Fabric (formerly IBM Tivoli SAN Manager) is currently the supported SAN Manager. The set of SAN Manager functions that will be exploited are: The ability to retrieve the SAN topology information, including switches, hosts, ports, and storage devices The ability to retrieve and to modify the zoning configuration on the SAN The ability to register for event notification, to ensure Productivity Center for Disk is aware when the topology or zoning changes as new devices are discovered by the SAN Manager, and when hosts LUN configurations change18 Managing Disk Subsystems using IBM TotalStorage Productivity Center
  34. 34. Performance Manager functionThe Performance Manager function provides the raw capabilities of initiating and schedulingperformance data collection on the supported devices, of storing the received performancestatistics into database tables for later use, and of analyzing the stored data and generatingreports for various metrics of the monitored devices. In conjunction with data collection, thePerformance Manager is responsible for managing and monitoring the performance of thesupported storage devices. This includes the ability to configure performance thresholds forthe devices based on performance metrics, the generation of alerts when these thresholdsare exceeded, the collection and maintenance of historical performance data, and thecreation of gauges, or performance reports, for the various metrics to display the collectedhistorical data to the end user. The Performance Manager enables you to performsophisticated performance analysis for the supported storage devices.Functions Collect data from devices The Performance Manager collects data from the IBM TotalStorage Enterprise Storage Server (ESS), IBM TotalStorage SAN Volume Controller (SVC), IBM TotalStorage DS4000 series and SMI-S enabled devices. The performance collection task collects performance data from one or more storage groups, all of the same device type (for example, ESS or SVC). Each performance collection task has a start time, a stop time, and a sampling frequency. The performance sample data is stored in DB2 database tables. Configure performance thresholds You can use the Performance Manager to set performance thresholds for each device type. Setting thresholds for certain criteria enables Performance Manager to notify you when a certain threshold has been exceeded, so that you can take action before a critical event occurs. You can specify what action should be taken when a threshold-exceeded condition occurs. The action may be to log the occurrence or to trigger an event. The threshold settings can vary by individual device.The eligible metrics for threshold checking are fixed for each storage device. If the thresholdmetrics are modified by the user, the modifications are accepted immediately and applied tochecking being performed by active performance collection tasks. Examples of thresholdmetrics include: Disk utilization value Average cache hold time Percent of sequential I/Os I/O rate NVS full value Virtual disk I/O rate Managed disk I/O rateThere is a user interface that supports threshold settings, enabling a user to: Modify a threshold property for a set of devices of like type. Modify a threshold property for a single device. – Reset a threshold property to the IBM-recommended value (if defined) for a set of devices of like type. IBM-recommended critical and warning values will be provided for all thresholds known to indicate potential performance problems for IBM storage devices. Chapter 1.
