  • Models such as the 620, 640, 650, S10, S20, S30, S40, and 150 are not supported by V5R3.
  • The Hardware Management Console for eServer uses its connection to one or more systems (referred to as managed systems) to perform various functions, including the following: Creating and maintaining a multiple-partitioned environment, including command capability to run scripted operations such as performing resource movement between partitions or start up and shutdown of partitions. Up to a maximum of 254 logical partitions, which includes a combination of OS/400, Linux or AIX, will be supported through HMC, Displaying a virtual operating system session for each partition, including granular operator authentication and authorization Displaying virtual operator panel values for each partition, including Remote system and control panel. Detecting, reporting, and storing changes in hardware conditions and acting as a Service Focal Point and Service Agent by gathering and reporting system error events. Powering managed systems on and off Activating Capacity on Demand resources On POWER5-based iSeries servers, HMC also supports 5250 emulator to support OS/400 console operations along with support for vSLIP that provides TCP/IP pipe through Service Processor and Power Hypervisor to OS/400 partitions. No additional network adapters are required on the server for these functions.

Hardware Management Console (HMC) <ul><li>Single console for POWER5 servers </li></ul><ul><ul><li>Pre-installed embedded OS </li></ul></ul><ul><ul><li>Supports local consoles, including 5250 </li></ul></ul><ul><ul><li>Web-based System Manager enables local or remote management for HMC control and status </li></ul></ul><ul><li>LPAR and CUoD </li></ul><ul><ul><li>Now configured and managed via HMC </li></ul></ul><ul><li>May 2004 - announce HMC Limits </li></ul><ul><ul><li>One HMC can manage a maximum of two i5 Servers </li></ul></ul><ul><ul><li>One i5 server can be managed by only one HMC </li></ul></ul><ul><ul><li>40 partitions per HMC </li></ul></ul><ul><li>July 2004 - announce HMC Limits </li></ul><ul><ul><li>One HMC can manage a maximum of 16 Power5 Servers (any mix of i5 or p5 servers) </li></ul></ul><ul><ul><li>A single Power5 Server can be managed by two HMCs (providing redundancy) </li></ul></ul><ul><ul><li>Maximum of 64 partitions per HMC </li></ul></ul><ul><li>Replaces primary partition and improves system resiliency </li></ul>
    5. 5. Why a Hardware Management Console (HMC)? <ul><li>Servers are becoming more virtualized </li></ul><ul><ul><li>Operating systems will continue to have less direct visibility and control over “real” server hardware </li></ul></ul><ul><ul><li>A place for hosting advanced platform management applications, outside of the operating systems, to do: </li></ul></ul><ul><ul><ul><li>Server configuration prior to operating system deployment </li></ul></ul></ul><ul><ul><ul><li>Service when operating systems are unavailable </li></ul></ul></ul><ul><ul><ul><li>Coordination of platform-related operations across multiple operating system images, in an independent security model </li></ul></ul></ul><ul><ul><ul><li>Presentation of virtual operating system consoles </li></ul></ul></ul><ul><ul><li>These functions should have common user and programming interfaces, independent of any one operating system </li></ul></ul><ul><ul><ul><li>Supporting both local and remote operation </li></ul></ul></ul><ul><ul><ul><li>A common delivery vehicle, which enables IBM to deliver more function, more quickly </li></ul></ul></ul>
    6. 6. When is an HMC Required on i5 System? <ul><li>Systems with multiple Partitions (LPAR) </li></ul><ul><li>Systems with Capacity on Demand </li></ul><ul><li>Systems with redundant service processors </li></ul><ul><li>Systems yet to be announced (High-end) </li></ul>
    7. 7. What is an HMC <ul><li>Based on xSeries server technology, built upon pSeries HMC device </li></ul><ul><li>Runs an IBM-provided GUI console application </li></ul><ul><ul><li>Not to be used with customer applications </li></ul></ul><ul><ul><li>Helps ensure a more stable console environment </li></ul></ul><ul><li>Required </li></ul><ul><ul><li>To create/modify partition – not to run it </li></ul></ul><ul><ul><li>For Capacity on Demand functions </li></ul></ul><ul><li>Not required to operate the partition </li></ul><ul><li>Saves the cost of typical primary partition </li></ul><ul><li>5250 interface for optional i5/OS console provided </li></ul><ul><li>Remote console by other workstations through HMC </li></ul><ul><ul><li>5250 interface via Telnet5250 client </li></ul></ul><ul><ul><li>Windows/Linux/AIX Client interface for HMC interface </li></ul></ul><ul><li>At August 2004 iSeries GA, one HMC can support a maximum of 64 partitions across up to 16 Power5 servers. </li></ul>http://www-1.ibm.com/servers/eserver/iseries/literature/index.html 7310-C03 (desktop) 7310-CR2 (rack)
    8. 8. HMC – More Details <ul><li>Based on xSeries server technology </li></ul><ul><ul><li>Minimum HMC configuration includes: 1 GB memory, 40 GB disk, DVD-RAM, 10/100/1000 Mbps Ethernet port, diskette drive, etc </li></ul></ul><ul><ul><li>Selectable options for HMC’s display, keyboard, etc (ordered separately) </li></ul></ul><ul><ul><li>HMC connects to POWER5 service processor which has two dedicated HMC ports. The ports are Ethernet ports. (Different from the two generic 10/100/1000Mbps Ethernet LANs.) </li></ul></ul><ul><li>Standard HMC maintenance support is CRU. Suggest upgrading support to IBM On-Site Repair to be more consistent with POWER5 server’s support agreement. </li></ul><ul><li>HMC not used on earlier iSeries servers </li></ul><ul><li>non-HMC i5/OS consoles are still supported </li></ul><ul><li>High availability suggestion: attached two HMCs to critical Power5 servers or redundancy. </li></ul>* Product preview
    9. 9. HMC “network” possibilities <ul><li>Local HMC: any physical HMC that is directly connected to the system it manages via a private network. Usually the first or only local HMC in your private network is a DHCP server in your private network and a DHCP client in your open network . </li></ul><ul><li>Remote HMC: any HMC used to remotely access another HMC or managed system. Remote HMCs are usually present in an open network Remote HMCs can also be local HMCs. </li></ul><ul><li>Web-based System Manager Remote Client: usually a PC installed with “Web-based System Manager” software. Use this PC to access other HMCs remotely. Web-based System Manager Remote Clients can be present in private and open networks. You can perform most management tasks using the Web-based System Manager Remote Client </li></ul>
    10. 10. <ul><li>Local GUI </li></ul><ul><ul><li>Starts automatically whenever the HMC is started </li></ul></ul><ul><ul><li>Requires user login prior to access </li></ul></ul><ul><li>Remote GUI </li></ul><ul><ul><li>Uses an installable standalone remote client application (WebSM Client) </li></ul></ul><ul><ul><ul><li>Windows (NT,XP) or Linux </li></ul></ul></ul><ul><ul><ul><li>Downloadable as an installable application directly from the HMC, using a web browser </li></ul></ul></ul><ul><ul><li>Also supported from one HMC to another, or from AIX 5L </li></ul></ul><ul><ul><li>Can be SSL secured through public/private key files </li></ul></ul><ul><ul><ul><li>Generate on the HMC, and transfer to client systems </li></ul></ul></ul><ul><li>Local Command Line </li></ul><ul><ul><li>Launched from a right-click menu option on the HMC desktop </li></ul></ul><ul><ul><li>Restricted to a set of supported HMC commands </li></ul></ul><ul><li>Remote Command Line </li></ul><ul><ul><li>Accessed through encryption-protected Secure Shell (SSH) </li></ul></ul><ul><ul><li>Key files can be set up and exchanged to avoid password prompts </li></ul></ul><ul><ul><ul><li>Very useful for automation and scripting without human intervention </li></ul></ul></ul>HMC User Interfaces and Access
