APAR status
Closed as program error.
Error description
This APAR is applicable for AIX/PowerHA environments where CAA (Cluster Aware AIX) clustering is used. . CAA uses a shared disk across all the nodes in the cluster called repository disk. This disk is used for maintaining cluster related configuration information. Disk is also used for health management through heart beating etc. . Note that PowerHA and CAA cluster survives loss of repository disk. Administrator can recreate the repository disk in such a scenario by using the PowerHA SMIT (providing a new disk to be used as repository disk) . This APAR describes an error scenario where loss of repository disk occurs and then all the nodes in the cluster also reboot. This would result in no configuration information available for the nodes to activate the cluster. CAA requires cluster configuration on the repository disk to bring up the cluster services during boot. . Note that in PowerHA environment, it is required that the repository related changes be performed through PowerHA (either using clmgr or SMIT menus. For more information refer to PowerHA APAR: IV50788)
Local fix
Problem summary
See above.
Problem conclusion
CAA maintains a local copy cache of the repository in rootvg. With this fix CAA has been updated to be able to restore the repository disk using this cache file. This CAA/AIX change is being exploited by PowerHA to support repository recovery in the case of loss of repository disk and the cluster outage. Refer to the PowerHA APAR for details in regards to the use of PowerHA clmgr command or SMIT menus to recover the repository disk
