Good info..

When you say " locking up necessary "tapes"" did those tapes show up as
"unlabeled" when devices would go offline?  I'm running into issues with
some devices in my edl's going offline.  I have "CDL" off also.

Subject: [Networker] Stable Backups... (What we run, and what was
changed...)

I have to admit this took much time to get to a stable backup
platform...

These is our environment that was working, mostly:
Sun Solaris 10u3 (T5240 sparc)
NetWorker 7.5.1
Sun StorageTek SL500 (6 drives)
EMC EDL (20 virtual drives)
Celerra with NDMP to EDL and SL500...

What fixed what....
#1) NetWorker 7.5.1 Roll-up 6, this has solved a few really annoying
client
issues, and an index issue, but by itself appeared to do nothing to
improve
uptime.

#2) We were running NMC on the Sun server, moved this to its own Windows
box
and...
    Indexer performed much better, especially around some MSSQL
issues...
    nsrim taking > 45 minutes to run...
    Random crashes - nsrd would simply be locked kill -9 only way to
shut it
down...
     -- to be fair this is EMC Best Common Practice, but they should
state
up front that your server requires two physical servers then...

 #3) Upgrade of the EDL code.
      EMC came out last week to upgrade our EDL code (and we were on a
fairly recent version already.
      We were suffering from virtual devices randomly going offline
locking
up necessary "tapes" some times stopping backups/clones/etc...
      We were suffering from TapeAlert messages about wrong medium...

This combo of changes has made our system seem to operate much better,
hope
this helps anyone out in a similar boat... its going to be difficult to
convince myself to upgrade things now though.. oh well :-).
