Abstract: IBM PowerHA/XD supports VIOS V1.5 on the IBM System Storage SVC Storage Software

IBM PowerHA/XD supports VIOS V1.5 on the IBM System Storage SVC Storage Software
September 25, 2008,

IBM PowerHA* Extended Distance (XD) for AIX, V5.3 and V5.4 adds support for the IBM Virtual I/O Server (VIOS) V1.5
to the IBM System Storage SAN Volume Controller (SVC) Storage Software V4.2.

Please refer to the following information for support details.
VIOS V1.5
SVC V4.2
SDDPCM V2.2.0.0
AIX V5.3
AIX V6.1
PowerHA V5.3
PowerHA # IZ07791
AIX V5.3 TL7
RSCT V2.4.8.0
PowerHA # IZ07791
AIX V6.1 TL0 SP2
RSCT V2.5.0.0
PowerHA V5.4.1
PowerHA # IZ13774
AIX V5.3 TL7
RSCT V2.4.8.0
PowerHA # IZ13774
AIX V6.1 TL0 SP2
RSCT V2.5.0.0

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".

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. (this feature added/restriction removed in PowerHA/XD 5.5)
  • PowerHA V5.3 does not support moving resource groups across sites.
  • For specific PowerHA CSPOC restrictions, refer to the "PowerHA/XD for Metro Mirror: Planning and Administration Guide", page 73
