Hi Everyone,
 
I've been having some problems with my backups since a week. I found
this list googleing around, hope you can spare a few minutes to read
this and maybe help me.
 
I don't know much of backups really, I needed to start and handle media
a few weeks ago. We usually have 12-15 tapes filled each day with
backups, half of it goes ofsite with a month retention (including
catalog tapes), half we keep here.... talking of daily backups of
course.
The guy before me showed me that sometimes tapes don't get deassigned
after expiration; he told me roughly how to check for this and how to
deassign/expire a tape manually.
He also told me I should place old catalog tapes back to scratch pool.
 
Now. As I started to understand more about netbackup, I realised we have
lots of frozen tapes. Tapes that always get assigned but don't get
written. I have turned on bptm log and noticed these are all old catalog
tapes (googled the error message). The problem is, since we always put
old catalog tapes back to scratch pool, the next day's catalog tape will
be a random tape. So, we just end up with more and more catalog tapes
that we cannot write on. I guess this was just a mistake noone noticed
before...
 
Anyway. I have unfrozen the tape and the next day it got frozen again.
Then I have found some docs saying that if you want to recycle a catalog
tape you need to relabel it. But, relabeling doesn't work for me...
tried 2 methods so far:
 
Z:\>bplabel -ev 000188 -d dlt
Requested number of drives are not configured
 
in the Activity Monitor I have:
 
12/04/2007 14:38:40 - begin Label
12/04/2007 14:38:40 - started process bplabel (976)
12/04/2007 14:38:40 - mounting 000188
12/04/2007 14:38:41 - Error bplabel(pid=976) Requested number of drives
are not configured
12/04/2007 14:38:41 - end Label; elapsed time: 00:00:01
error requesting media (tpreq)(98)
 
Then I tried to relabel using the GUI:
12/04/2007 14:41:49 - begin Label
12/04/2007 14:41:49 - started process bplabel (77988)
12/04/2007 14:41:49 - mounting 000188
12/04/2007 14:42:39 - mounted; mount time: 00:00:50
12/04/2007 14:42:42 - expected media 000188; found NetBackup media
12/04/2007 14:42:42 - end Label; elapsed time: 00:00:53
media manager found wrong tape in drive(93)
 
Okay, I know sometimes you can get error if the media type is different
- I am not even sure how to check what it is...
For example I got this tape:
C:\>vmquery -m 000200
========================================================================

This tape is one of the many I am keeping an eye on since the past days
and can't get to write them. I also tried to delete it using 'vmdelete',
hoped netbackup will forget about it but it didn't - at the next backup
try the tape got frozen again because "it contains VERITAS NetBackup
(tm) database backup data and cannot be used for backups."
 
If you got any ideas, please don't hesitate to help me.
 
Thanks,
Endre
