  • Closed as program error.

Error description

  • This APAR fixes several related issues in the AIX support for
    DS8k Hyperswap disks.  The most visible issue is the case
    where a Failed path to a Hyperswap disk does not recover
    automatically because the health check process has aborted
    on the disk.  There is also a chance for ordering issues
    between the disk quiesce and the response to an event, where
    the event times out before it should.
