MKSYSB Support of Live System Backups
• Motivation
– Desire to reduce system downtime (inactivity) when using the native
system backup tools for AIX.
– Additional requirement for guaranteed image integrity (upon completion
of an image capture).
• Details
– Provides a consistent backup even in the presence of a workload that is
creating and deleting temporary files.
– Create a volume group backup (mksysb, savevg, savewpar, mkcd, or
mkdvd) using the new -T flag while such a workload is running. There
should be no errors about missing files, even if files were deleted while
the backup was running.
– Requires either pre-GA AIX 6.1 TL9 or pre-GA AIX 7.1 TL3
• Benefits
– Includes the ability to capture a system backup without the worry of
having files change prior to completing the archive.
– Ideal for capturing backups of production systems.. where quiescing the
machine isn't always possible.

AIX WPAR Lifecycle Management
Alt-Disk-Copy for WPARs
• Motivation
– Desire to exploit advantages of alt_disk_copy for an LPAR that
includes WPARs. In particular, desire to “roll-back” to original
LPAR and original WPARs.
– Desire to create an alternate copy of a WPAR, make
experimental changes to the WPAR, and quickly roll-back to the
original WPAR if needed.
• Details:
– New chwpar command options
• Create alternate copy of the WPAR “bootset”
• Start the WPAR from a different “bootset”
– Does not apply to Versioned WPARs (5.2 or 5.3)
– Requires pre-GA AIX 7.1 TL3
• Benefits
– Same maintenance methodology possible for LPARs with
WPARs
– Quick roll-back capability for WPARs

Migration of AIX 5.2 and 5.3 Versioned WPARs
• Motivation
– Interest in 5.2 or 5.3 Versioned
WPARs as a tactical solution until
able to migrate to 7.1
– Already running 5.2 or 5.3 Versioned
WPARs, now ready to migrate to 7.1
• Details:
– Existing migwpar command
extended with the capability to
migrate the 5.2 or 5.3 WPAR to a
WPAR at the same level as the global
LPAR (7.1)
– Operates on Stopped WPARs only
– Requires license of 5.2 or 5.3 WPAR
– Requires 7.1 install filesets
• Benefits
– Ability to maintain currency
– Flexibility to migrate when ready

Power Systems SR-IOV Solution
Industry Standard I/O Adapter Sharing
• The Single Root I/O Virtualization (SR-IOV)
Specification defines extensions to the PCI
Express (PCIe) Specification to allow multiple
partitions to share a PCIe device.
Features
• Adapter sharing
• Improves partition to I/O slot ratio
• Sharing by up to 48 partitions per adapter. Additional
partitions with Virtual I/O Server (VIOS)
• Direct access I/O
• Provides CPU utilization and latency roughly
equivalent to dedicated adapters
• Adapter sharing with advanced features such as
Receive Side Scaling (RSS) and adapter offloads.
• Adapter resource provisioning (QoS)
• User designates desired capacity for a logical port.
• Simple server I/O deployment
• Minimal steps to add a logical port to a partition or
partition profile.
• Flexible deployment models
• Single partition
• Multiple partitions without VIOS
• Multiple VIOS partitions
• Mix between VIOS and non-VIOS partitions
