Nick,
If you just want to preview - don't use the "TOS=" parameter and no
tape mounts will be done.

Subject: [ADSM-L] MIGRATE NODE oddities
z/OS TSM 5.4.3.0
AIX TSM 5.5.1.1
MIGRATE NODE doesn't seem to preserve collocation group membership.
Is this WAD or a bug? (I can see arguments about how complex it gets if
the target node doesn't have the collocation groups defined, but this
doesn't even try!)
Also, "MIGRATE NODE yyy TOS=xxx FILED=ALL FSID=1 PREVIEWI=YES" is
reading the source tapes! I was hoping (and expecting!) it to get the
needed information from the database without mounting tapes. Heck, part
of the intent of the PREVIEWI=YES was to avoid introducing tape
contention issues on the older, production server as I stand up its
replacement.
Again, is that a bug, or sign of a user error, or just WAD? (BAD?) Does
the behavior change if I don't specify the FSID?
Guess what I'm doing this month!
Thanks,
Nick
