Forgive my ignorance about that number, but some numbers once set stay
that way until they are reset. Is this one of them? I'm thinking that
maybe at some point in the past there were 8 failures even though
recently there haven't been any.
Like I say, there's a lot I'm still picking up on

Have you looked into ndmp from the filer to your tsm server? If you
are at TSM V5.4 you can do this over ethernet and handle the data
just like any other node - move, copy etc. It also minimizes impact
on DB

I've thought about replacing the 3590 drives with 3592 but I'm

Wanda said some balanced things about 3592 vs. LTO4. I share her
empirical observations, but conclude
We migrated from an L700/ACSLS/LTO3 to TS3500/TS1120. Since that
migration, we have been able to stop troubleshooting library/server/tape
issues and focus on client issues. The TS3500/TS1120 combination (with
encryption) just plain works.

But the 3584 we have remotely is
bloody -fast-. Scary fast.
I flinch evertime I watch the robot in the 3584 and it moves to
the home frame. I keep thinking it's going to fail to stop and break
through the window.

I believe there is a mistake here.
I believe that the cache is only used to cache the ccw's for blocks. The reason
for the 2gig limit was given a long time ago on this list by a TSM dev, they
use a windows api to map the file in virtual memory for i/o. The api they use
has the 2 gig limit.

As has been noted already, subfile backup was originally targeted mainly
for remote workstation/laptop users coming in over slower network
connections. Most of these users (so we thought) would not be dealing with
such large files. While subfile can technically be used in higher

The earlier description on subfile backup is not correct.
The cache does NOT hold a copy of the original file for files 3M.
It keeps a file that stores a MAP of the blocks of the original file.
The TSM Server stores the original file, and the subfile differences.

the subfile cache doesn't hold the whole file, it holds signatures of

Setting up NDMP is almost a trivial task when using TSM V5.4 and NetApp
filers.
There is no device driver set up on the filer - just enable NDMP.
Schedule snapshots if you want to backup a snapshot for a specific time.
Create two primary storage pools (one for data one for the table of

I have a question, as I've been challenged to provide this information.

There is no one-to-one correspondence between filespaces (or nodes) and

and policy domains, and a policy domain has one DEFAULT management

It's highly overrated with

scroll right to see the management class that each file is bound to
