Hi,

1) You can change ownership of a scratch volume by using the 'upd libv
owner= stat=' command. See help upd libv
2) Yes, the volumes used by the library client (TSMSun) will be return
to the scratch pool. The scratch pool is managed by the library manager
and both ITSM servers can use tapes from the same scratch pools.
3) TSMSky is the library manager and as such managing the total number
of scratch tapes. If TSMSky is running out of scratch tapes, there are
no scratch tapes available. Not something you would like to see happen.

The q libv command will not work on the library client. 

Regards,

Karel

Subject: volume owner

Hello,
      I noticed that when I do a query ' q libv' , it shows a list of
volumes with 'Private ' and 'Scratch' status. We have two instances,
TSMSky and TSMSun shared the same library 3584.
My question is ...
1) how do you designate ownership to volumes?
2) does the ownership change back to null, once it has returned to
scratch?
then TSMSky or TSMSun can claim the scratch for their use later?
3) If TSM Sky ran out of scratch volumes, will it move automatically to
TSMSun to use those scratch volumes under ownership of TSMSun?
