How many inactive versions exist??? (what are your retention characteristics
and how frequently do the files change)
Also, what is the total number of files stored for that file system???
If you have 7 million files in that file system, that can have ugly
results...
Also, do you have any looping links??? And by that I mean, in any of your
subdirectories, do you have links that point back up the directory path?
You can spot that by looking for ANE4017E's

ANE4017E   Error processing 'filespace namepath-namefile-name': too many
      symbolic links were detected while resolving name

Explanation: While trying to resolve the file name, too many symbolic
links were found.

System action: File skipped.

User response: Ensure that you do not have a looping symbolic link for
the file.


Looping links can cause issues such as what you are seeing...

Subject: [ADSM-L] slow restore

We are performing a restore that is running real slow.

client:  hpux 11.11, tsm v5.5.0
tsm server:  v5.4.1

The restore operation is about 1000 files totaling about 600gb. The tsm
server is sitting with the session on SendW.    When dsmc is first started
it runs the restore at about 10-15mb/s.  After some time (an hour or so) it
slows to a crawl.  The problem appears to be that dsmc is running an entire
processor flat out at 100%.  In other words, dsmc becomes cpu bound.  We
have killed and restarted it several times and the same pattern occurs.

Here is dsmc cmd we ran:
dsmc restore /oracle/backup/fedwp1/bkup.hpdw1p.200903081920.fedwp1.hot/
/oracle/backup/paul/ -inactive -subdir=yes -replace=no

Any thoughts on what's happening would be appreciated!

Rick
