Can anyone comment on what kind of speeds you are seeing on LTO-5 tape
drives? Any information is much appreciated.

to the active/passive active/active philosophy, similar to
clustering the TSM server. If they are both active at the same time,
then you need licenses.
Hope this helps.

Thanks all for the response. I agree with al the statements made. I

specs on the LTO5, or what the real world transfer rates are.

Since then the TSM server has been stable.

In short no. Sanergy is what allows you to share the filesystem
amongst multiple servers. GPFS is a an alternative to SANergy that
also provides the file and block locking necessary to share a physical
device among multiple hosts.
I may be wrong, but I believe that the only two supported LAN

Sounds like you've got the same client name on two different servers.
Each time they check in with TSM, they are updating their IP and
GUID. Go check the dsm.opt on both those servers.

My guess is that you are mounting up the filesystem, and backing up
the files directly. The log files in Exchange are probably getting a
new name as they are truncated, which means that there are no versions
of the files, only a single version that goes from active to inactive
when it is deleted
It is all based on PVU. For virtual machines you are paying for the
number of processors of the ESX server.

Bill,
From what I read on your thread you are only keeping 30 days worth of
backups. You may already know this, but the fromdate and todate on
the export pertain to when the backup was taken, not the timestamp of
the file. I'm sure you know this, but I want to be sure.

Hate to say it, but this looks like DB corruption IMHO. If you have
the downtime, or another test server, I would run an audit against the
DB.
Also, since the error seems to be on the BFDESTROY, you might try
setting the trace flag for SHRED. Maybe this will give more
information.

One more thing. Are any of your database volumes marked stale or
offline? It could be possible that a bad DBMIRROR would cause this.

Without the errorlog, it is difficult to diagnose. Try starting it in
the foreground first. Open a windows command line, and run dsmc
sched. This will give you a good idea of what is going wrong. Also,
look at the dsmwebcl.log and dsmsched.log. It could be a simple
password issue.

soon.
