Failure effect
If the LUN is not shared, I/O is suspended or process is terminated across this HBA
until path is restored.
If running OpenVMS 7.3-1 and the LUN is shared, another cluster node having
direct access will take over serving the device, resulting in no loss of service.
In either case, no data is lost or corrupted.
The operating system will report the volume in a Mount Verify state until the
MVTIMEOUT limit is exceeded, when it then marks the volume as Mount Verify
Timeout.
