Hello everyone
I get this error for a volume when I run a backup stgpool.

You need more scratch tapes. Load more scratch tapes and backup the storage pool again. If you have spare scratch tapes, then you may need to increase the maximum number of scratch tapes allowed for the LTOPOOL2 pool.

q stg LTOPOOL2 f=d would give us more information on the pool.


Notice how the tape details show the tape as 50.4% full and the tape is in filling state? TSM doesn't know how much data it can squeeze onto the tape as with compression, mileage varies. Your device class (LTOCLASS2) is set to guess that it can probably fit 6TB onto a tape. When copying out the last file, it reached the end of the tape and tried to load a new tape. This failed as you were either out of scratch tapes or the storage pool is using it's maximum allowed number of tapes and can't get another.

Hi Daz,
I added more scratch as you suggested but it still gives me the same error.

How exactly did you added more scratch tapes?
Did you just loaded some scratch tapes into the ATL?
If so, did you run the checkin libv command?

Are the scratch tape(s) new or have they been used by the TSM Server?
If they are new scratch tapes, need to run the label libv command .


Good Luck,
Sias
 
Hi Sias,
I ran the checkin libv
CHECKIN LIBVOLUME <library name>2 search=bulk checkl=b status=scratch
(SESSION: 27211)
These are new tapes. The new tapes are being used by other processes but the backup stgpool script keeps picking an old tape (XT0026L6).

Thanks
Devam
 
These are new tapes.

Since the scratch tapes are new.

When you use the tape volumes for the first time, you have to label the tapes to be recognised by the TSM server.

Need to run the checkout libv with the checklabel=no.
Once the new scratch tapes have been checked out , need to run the label libv with the overwrite=yes.

NOTE: If you run the label libv with the overwrite=yes on the wrong tape.
There's no "undo".

Good Luck,
Sias

Thanks Sias! It worked.
