What sort of tape drives/library is it? It isn't some sort of de-dup'ed
library (non-IBM) is it?

regards,
Mark

Well I started the restore and went home, so I don't know how many mounts
it did, but the data was on 3 tapes

09/04/2010 11:34:41  ANR1182I Removable volume 006811 is required for a
restore
                      request from session 2060. (SESSION: 2060)

09/04/2010 11:34:41  ANR1182I Removable volume 005763 is required for a
restore
                      request from session 2060. (SESSION: 2060)

09/04/2010 11:34:41  ANR1182I Removable volume 005902 is required for a
restore
                      request from session 2060. (SESSION: 2060)

09/04/2010 11:34:42  ANR1183I Initial determination of removable volumes

                      required for a restore request from session 2060 is

                      complete. Additional volumes may still be required.

                      (SESSION: 2060)



And it looks like it only mounted the tapes once, except for 006811, which
got mounted 2 times:

During the restore, the "original" server did a backup, does  my restore
somehow collide with the running backup?

09/04/2010 11:37:06  ANR1639I Attributes changed for node FSPAS01FS039: TCP

FS039 is the fileserver, and my ws is WS25658

How many tape mounts did you see during  the restore?

I actually restored the files to my workstation, and the network settings
are fine
Duplex mismatch does not cause the speed to go down to modem-speed from
1995....

The TSM DB is really big, 180Gb and 94% full.

your network sucks? (to put it mildly :) ) I'd check to see if there is any
mismatch in duplex settings anywhere. Remember, auto-negotiation on the
host, and a fixed 100 full-duplex setting on the switch will lead to a host
at half-duplex and tons of collisions.
