RE: pointing a tsm ndmp mover at smo-fired snapshots

I've done this kind of thing, but using NetBackup rather than TSM via a
script (this was on an AIX server). The steps I used were:
-Create a profile in SMO which would only be used to take snapshot
backups that would be dumped to tape (called say BACKUP) and only keep
the minimum number.
-In the script, have the previous nights BACKUP snapshot deleted and
then have another snap taken using this profile.
-Once the snap is taken, use SSH to get a list of snapshots on the
Oracle volumes, and look for the snapshot name which contains the name
of my profile BACKUP (SMO snaps at least have the name of the profile
used in them)
-Once the snapname has been gathered, then manipulated the backup
policies in NetBackup to add the volume names with the snap names above
-Kicked off a manual backup of the policy
Assuming you can manipulate the backup specification in TSM from the
command line, I'm sure you could apply this method to TSM as well.

Toasters --
We are currently looking for a means to point a TSM NDMP mover at
SMO-initiated snapshots. The TSM maintainers are currently defining
'virtual filesystem mappings' to point the TSM NDMP mover at WAFL snaps
on non-Oracle volumes. This works like a champ due to consistent naming
with scheduled WAFL snaps (nightly.0, etc). Since introducing SMO, we
now have quiesced, consistent Oracle data in snapshots. Unfortunately
the naming of these SMO snaps is nowhere near as graceful as
'nightly.0', to the chagrin of TSM.
Has anyone here dealt with reconciling SMO snap name spew along with
pointing a TSM NDMP mover at a consistently-named SMO snap space?
Insight appreciated. Thanks.
