  • Closed as program error.

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.

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.
