Hoping someone out there may have seen something similar and have one of
those great (wished I though of that) solutions?
We are running 4.0F trucluster on a GS140 pair. Patchkits 4 + bits of 5 are
on both.
The backup tapedrives are a pair of TL800 with a pair of TZ89s in each and
we are using DLT IV tapes.
Backup has been working fine until about a month ago. Since then the
validity of the backups has varied from no sets valid to all sets valid.
Even this mornings tapes, 2 backup tapes were totally worthless but one has
the first 3 backup sets valid but the forth is corrupt.
Compaq has replaced the tapedrive where the symptoms were first noticed
(drive 0) and compaq will be brought back into the loop again now that all 4
tapedrives are producing the same problems. I will be looking in the
archives today as well.
The difficulty is that VDUMP is writing successfully (or so it thinks). We
only find the problem when trying to vrestore from the tape. Just shows that
you should always double check your tapes and backups.
Is it;
1. The tapedrive library
2. The SCSI cards
3. The tapedrives themselves
4. The VDUMP command
5. The VRESTORE command
6. Other
With all the testing and swapping of tapedrives between systems, I am
leaning toward the tape libraries themselves.
Any suggestions would be greatfully accepted.
