The Question is:
The Perennial Mounted/Dismounted disk problem!
(This is such a common problem in LAVC, I was sure I would find it in
the FAQ, but no such luck??)
In a LAVC after a satellite is rebooted, a batch job on different host than the
rebooted satellite causes the remote disk to MntVerifyTimeout and becomes
Mounted/Dismounted - all attempts to either dismount or mount the remote device
return a device is already [dis]mounted message.
What action apart from rebooting the host where the batch job was referencing
the remote disk can be performed to bring the volume that is once more
accessable into a mounted state.
The Answer is :
What you are describing appears to be a bug, or some sort of local
configuration error -- there is unfortunately insufficient detail
on the problem and on the local batch environment included here for
a more specific answer.
Please contact the Compaq Customer Support Center for assistance in
resolving this situation.
The usual approach for mounting disks within a cluster environment
is via local customizations to the provided SYS$EXAMPLES:MSCPMOUNT.COM
DCL command procedure.

As for normal processing, if a batch job requires a specific disk, it
can express this interest via a MOUNT command -- this MOUNT will succeed
in parallel to the more typical shared MOUNT (MOUNT/GROUP, MOUNT/SYSTEM,
MOUNT/CLUSTER) used to make the target disk generally accessable, and
will keep the disk mounted for the duration of the batch process when
an operator (attempts to) manually dismount the target disk.
