Thanks to everyone for all of the advice. My vendor has now assigned a new TSM technician that knows about the Library Manager. Now, another issue has come up about this.
I have 6 LAN-free clients, one of them is running on AIX in an HA environment. I am assuming that all of the drives will need to be reconfigured once the Library Manager is online and the server to server communication is redone on the Manager and Clients. For now, the LAN-free clients will belong to the original server and the library communication will of course be to the Library Manager. Any gotchas in changing these clients, especially the HA client? -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] Behalf Of Richard Rhodes Sent: Thursday, October 16, 2008 11:31 AM To: [email protected] Subject: Re: [ADSM-L] Library Manager and Migration question some more comments . . . > > 228GB.

We created new instances, then started assigning all new clients to the new instances. Then, we went back and cherry picked the handfull of worse clients and moved them to the new instances (some by occupance, some by number of files). To move them, some we exported/imported while others we just created new nodes on the new instance and retired the node on the origional TSM server. > > Our current library configuration > > has the library shared but it is not a library manager since we only had one > > server.

The procedure CAN seem complicated, but when you work through the steps it's not bad. The only trick in the procedure is making sure the library manager assigns the volume ownerships to the clients correctly. This is all in the procedures. First, make sure you understand how library sharing works (see the Admin guide), then the redbook on converting to it. I spent a fair amount of time working through the examples. I then wrote a detailed procedure for the conversion (sorry, I looked for it but can't find it), then got the outage and performed the conversion. Understand, plan/plan/plan, ask questions, then do it. If you can think of a way to test out a small library sharing environment first, then do it. We were able to do this since we had new 3584 libraries onsite that were waiting for library sharing to go in to use them. We used them to setup a small library sharing environment to play with. > > I currently have over 1000 tapes > > onsite and as many offsite and naturally do not want to lose any data. You won't! We had over 6-8thousand tapes in 2 3494 libraries and 2 3584's with 300-400 tapes. We didn't loose a single tape when we converted! The library manager environment has it's own issues you will need to get your arms around. We spent some time balancing the batch schedules between instances so as to not have one instance hog the drives. It also becomes fun trying to get a big picture of what all the instances are doing. I finally wrote a script to give a overall picture of tape drive usage across the instances, and what processes/sessions were using them (see below).
