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

Failure effect<br />
OS reboots. When mounting volumes, volume repair or NSS rebuild<br />
executes to cleanup volumes. Data loss, data that finished writing<br />
survived.<br />
I/O to device stops with I/O errors indicated on server console.<br />
Applications using lost connection halts. Server restart recommended<br />
but may not be necessary. Volume repair or NSS rebuild runs when<br />
volumes are mounted.<br />
