The Question is:
We have a number of TZ8x tape drives in remote locations for our backup
operations. Our problem is that the people who change the tapes for us are not
computer people, and occasionally a cleaning tape is required. My question is:
How can I tell from VMS (
F$getdvi?) if a TZ tape drive is requesting a cleaning tape?
Thanks,
The Answer is :
The drives in some recent libraries will set the exception bit in
the drive's Read Element Status data and set the ASC/ASCQ values
to a vendor unique that means "needs cleaning".
On a system supporting the MRU API, it would not be difficult
to write a program to do periodic scans of the DLT drives looking
for the specific exception, track down the cleaning tape (assuming
the standard CLN prefix barcode), and move it to the DLT drive and
then back when done.
