Error description
When there are multiple failures between AIX and the storage device, there are cases where the AIX PCM does not raise the "failover required" event to PowerHA. This can lead to Power HA not performing a failover when it could, and thus loss of access to the Hyperswap disk.
Local fix
Problem summary
When there are multiple failures between AIX and the storage device, there are cases where the AIX PCM does not raise the "failover required" event to PowerHA. This can lead to Power HA not performing a failover when it could, and thus loss of access to the Hyperswap disk.
Problem conclusion
Updated the hyperswap select path code to detect scenarios where a failover is possible and required but that has not been raised to Power HA. Added the event when needed.
Temporary fix
