Good!

Instead of trying to explain this properly in an email I refer to the author of 
adsm quickfacts plus the BA client guide, Classic restore vs No Query restore.

Thanks to Henrik Wahlstedt this got solved.

Henrik, tack för hjälpen och telefonsamtalet, jag har faktiskt inte fått nåt 
mail från dig...


Restore processing finished.

Total number of objects restored:       137
Total number of objects failed:           0
Total number of bytes transferred:   59.12 MB

The first restore had the filespecification:
restore "\\fspas01cl001\z$\mpy-it\users\p950kaz\my pictures\pic\*"

If I changed it to  restore "\\fspas01cl001\z$\mpy-it\users\p950kaz\my 
pictures\pic\?*"
The client got direct "waiting for offline media" and started to restore the 
files after the tapes got mounted

So I tried again with only *, and got the same problem as before:

tsm> restore "\\fspas01cl001\z$\mpy-it\users\p950kaz\my pictures\pic\*"
tsm> c:\restored2\ -subdir=yes
Restore function invoked.

ANS1247I Waiting for files from the server...


Some questions:
Whats the difference between ?* and only *

Why don't I see a restore session when I ran q restore with the ?* filespec,
tsm: ADSM4>q restore
ANR2034E QUERY RESTORE: No match found using this criteria.
ANS8001I Return code 11.

And the restore starts right away

When I run with only * I get this in the log:

2010-09-07 10:51:52 ANR1182I Removable volume 006811 is required for a restore 
request from session 2717.
2010-09-07 10:51:53 ANR1182I Removable volume 005763 is required for a restore

2010-09-07 10:51:53 ANR1183I Initial determination of removable volumes 
required for a restore request from session 2717 is complete. Additional 
volumes may still be required.

Hi,

I'm sorry, but you are wrong, duplex mismatch Does cause the speed to drop to 
Aboutaleb 5K/s. I've Deen Thissen on numerous occasions.
