IV65069: NORMAL MODE OPEN FAILS AFTER DIAGNOSTIC OPEN/CLOSE ON DISK APPLIES TO AIX 7100-03
A fix is available
Closed as program error.
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.
normal mode open call to disk may fail with EACCESS error code
code is modifed to fix the timing issue.
