Hi.
We are migrating to a new library with all LTO4 drives. I created a Device Class for LTO4s and labeled some tapes. I'd like though, to use my LTO3s for long term vaulting such as backupsets...
I thought, i'd create a LTO3 devclass, then when generating the backupset with the option deviceclass LTO3 that i would mount a LTO3 tape and write to it...But no.
The behavior i am seeing, is that it mounts every single LTO4 scratch tape, fails on it and puts it in a "private" status to prevent reuse...! Then, when it finally reaches a LTO3, it starts...It seems to grab the LTO4 first, since the are numbered for example 110000L4 whereas the LTO3 are 700000L3. So it looks like it grabs the "smallest" numbered tapes first...
So, what are Device Class for then? I thought, that when labelling the tape, TSM would "know" that he just labeled a LTO3 thus picking one up right away when i specify to use LTO3 devlclass?
If not, apart from scripting it...any ideas?
Thanks.
