OK, This begs some additional discussion. This presumes that there is a one to one relationship between the device class and the storage class in the TSM environment. But, there is probably not a single installation like that. I believe in this case the installation only wanted to move some tapes to the new library, not all. In the all scenario, changing the device class works fine.
The issue that I see is that a storage pool in the future will need to span more than one library simply because of the number of needed devices and exploiting the flexibility of SANs. I hope TSM Development is working on this. In our case we have two 3494s, one with 16 drives and one with 22 drives. It is really a pain to have to worry about which library a tape will be inserted into when it returns from the offsite storage. It also limits us when a SAN client is limited to one library for a storage pool of scratches because the storage pool cannot span, but I can see how difficult it could get to support cross library functionality. So, I guess the only way to move from one library to another is by doing a client move from one storage pool to another. -----Original Message----- From: Kelly Lipp [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 25, 2001 3:11 PM To: [EMAIL PROTECTED] Subject: Re: Changing Library box Not quite. You need to update at the device class that pointed to old library and have it point to the new library: update devclass devclassname library=newlib Then TSM will look for the old device class volumes in the new library.

According to the administrator's guide what you did is the proper way to checkout and checkin a volume to a library. But, it does not say you can move the volume to a new library (device class/storage pool). This is what I am speculating. You cannot change the device class of a in a storage pool without deleting and redefining it. Once a tape has a private status I am betting you cannot do what you are trying to do. However, if the tape has no data on it and you change its status from private to scratch I am betting you can check it out and back in to a different library. Yes, this sucks. Remember TSM manages objects between storage pools. So, you can move all the data off a volume easily with the move command. Then you should be able to change the status of the volume to scratch and move it. I do not know if you will have to run expiration to be able to change the volume's status. I have not tried this but bet that this is the situation. I think there is a requirement here for us to be able to associate a super device class to a storage pool that contains many libraries and to be able to change the location of a volume so long as it is in the super device class. Maybe Andy has an idea. -----Original Message----- From: Michel David [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 25, 2001 6:31 AM To: [EMAIL PROTECTED] Subject: Changing Library box Hi all TSM'rs I want to change my library from 20-tape lib to a bigger.
