We are running TSM 3.7.3 on OS/390 2.8. We are getting ready to upgrade our tape
drives from model B's to model E's. IBM says that the upgraded drives will read the
old tapes just fine, but will write them at the new density. I am unable to determine
what, if anything, I need to do to configure TSM for this change. The deviceclasses
only define "3590" with no model information. The capacity information for the old
density tapes will not be correct when it starts writing at the new density. Is this
something that TSM will adjust automatically or do I need to reset it somehow?
Are there any problems I'm not thinking of that might bite us with some tapes at the
old density and some at the new, once TSM starts writing tapes with the upgraded
drives?
Anything, else I should be looking at.
Thanks for any advice.
