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
