IBM PowerHA* (formerly HACMP*) for AIX, V5.3, V5.4.1, and V5.5 including the PowerHA/XD optional feature adds support for the IBM System Storage SAN Volume Controller (SVC) Storage Software V4.3.

Please refer to the following information for support details.



SVC V4.3 & 4.3.1
AIX V5.3
AIX V6.1
PowerHA V5.3
PowerHA # IZ07791
AIX V5.3 TL7
RSCT V2.4.8.0

PowerHA # IZ13774
AIX V5.3 TL7
RSCT V2.4.8.0
PowerHA # IZ13774
AIX V6.1 TL0 SP2
RSCT V2.5.0.0

Notes:

The clverify function will always report "ERROR - SVC PPRC license is not activated on SVC" for SVC 4.3 when used with the XD feature, even when the license is valid. However, this message will not prevent verification from completing successfully. The following APAR should be applied to avoid having this message sent unnecessarily**:
  • PowerHA V5.3 - IZ39725
  • PowerHA V5.4.1 - IZ39727
  • PowerHA V5.5 - IZ38319

While not required for correct operation with SDDPCM, the configuration of Fast I/O Failure on fiber-channel devices is highly recommended. For information on configuring this feature refer to "Storage Multipath Subsystem Device Driver User’s Guide".


** These APARs are not yet generally available. Please contact IBM Support to obtain Interim Fix (IFix) packages.


Additional Requirement:

The AIX OS error daemon parameters should be tuned to avoid lost log entries. PowerHA requires the buffer size be set to at least 1 MB and the log size to 10 MB. The following command can be used:
"errdemon -B 1048576 -s 10485760"

Restriction notes for Metro Mirror:
  • Although SVC Host Name Aliases are arbitrary, for PowerHA's support of Metro Mirror they must match the node names used in the defined PowerHA sites.
  • Resource Groups to be managed by PowerHA cannot contain volume groups with both Metro Mirror-protected and non-Metro Mirror-protected disks.
  • PowerHA does not support Global Mirror functions of SVC Copy Services in PowerHA V5.3 and V5.4.1. However this feature was added in PowerHA V5.5.
  • PowerHA V5.3 does not support moving resource groups across sites.

For specific PowerHA/XD CSPOC restrictions, refer to the "HACMP/XD for Metro Mirror: Planning and Administration Guide"
Refer to the PowerHA/XD (formerly HACMP) support statement of VIOS for restriction information:
