I was not restoring only one BOX , there were 3 Boxes production and development
and another Sun box, ..Which I restored successfully. Assuming your data is on
multiple volumes, TSM will try to mount all tapes, provided sufficient drives
available ,I configured all available drives from stk9710 in daisy chain ..
After that TSM utilized lot of drives, to restore data. TSM was mounting 5-6
tapes at a time..
As I was issuing commands like :
dsmc restore /ora01 ?subdir=yes ?latest /ora01/
dsmc restore /ora02 ?subdir=yes ?latest /ora02/
dsmc restore /ora03 ?subdir=yes ?latest /ora03/
dsmc restore /ora04 ?subdir=yes ?latest /ora04/
dsmc restore /ora05 ?subdir=yes ?latest /ora05/
dsmc restore /ora06 ?subdir=yes ?latest /ora06/
dsmc restore /ora07 ?subdir=yes ?latest /ora07/
dsmc restore /maetsro ?subdir=yes ?latest /maestro/
etc?
In your case if you are restoring only one BOX, I don't know how TSM will treat
that operation.. , try starting multiple restore sessions. and don't use GUI
to start multiple restore sessions , and
It boost performance.. See page 62 of redbook using backup/Archive client
version 4 release 1
For more details..
Let me know what exactly you are doing so that i can help you , can write me on
