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.
