APAR status

  • Closed as program error.

Error description

  • If two threads are opening a disk at the same time and
    one
    of them is using the SC_DIAGNOSTIC flag, it is possible
    to
    experience an unexpected open failure under certain
    timing
    conditions.
    
    This problem has been seen in EMC powerPath environments
    when
    two user processes concurrently try to open the
    hdiskpower
    device and one of its underlying hdisk devices. When this
    problem is hit, powerPath may log EMCP_PATH_DEAD /
    EMCP_BUS_DEAD / EMCP_PATH_ALIVE errors in errpt.
