IBM PowerHA SystemMirror for AIX* V6.1 and V7.1 for AIX V7.1 supports IBM AIX v5.2 and v5.3 Workload Partitions for AIX V7.1 (Compatibility WPARs).

It is recommended to obtain the latest service updates for this support.

Please refer to the following information for support details. The specified levels, or later, are required for this support.

The prerequisites for AIX 5.2 Workload partitions are as follows:
  • Versioned WPARs only support POWER7 hardware.
  • Versioned WPARs can be installed only on an AIX 7.1 operating system.
  • The latest available, and supported version of AIX 5.2 is technology level (TL) 10, and service pack (SP) 8.
    Therefore, any backup image that is used to create an AIX 5.2 WPAR must be from an AIX 5.2 system running the latest version.

Restrictions:
  • PowerHA does not support devices that are exported to WPARs. Due to this, rootvg disks for Versioned
    WPARs are not supported by PowerHA.
  • PowerHA 7.1 support for Versioned WPAR is restricted to 32 Service IP addresses (per WPAR-enabled
    Resource Group).
  • Mixed mode operation, where in some of the nodes of the WPAR-enabled resource group has Versioned
    WPAR software installed whereas some other nodes do not, shall not be supported by PowerHA.
  • Cloning (via the PowerHA corrective action) of WPAR profile, shall not be supported for Versioned
    WPARs (in PowerHA).

Notes:
  • WPAR property changes do not take effect until the next time the resource group is brought on line
