Hello,

I was told that this could work If I have 2 backup disk pools.

Like I have backup diskpool, then I can have like say a DB2 backup diskpool
then I can have the next storage pool setting for the db backup pool so I
can migrate to the one Library then for the other backup disk pool
I can have it migrate to the other Library.

I think I can have simultaneous write to two different libraries
this way. Still not sure if this would work.

   TSM Library setup

  TSM  SERVER  LTO_LIB  LIBRARY

  TSM  SERVER  RMT1  DRIVE  LTO_LIB
  TSM  SERVER  RMT2  DRIVE  LTO_LIB
  TSM  SERVER  RMT3  DRIVE  LTO_LIB
  TSM  SERVER  RMT4  DRIVE  LTO_LIB

  TSM  SERVER  RMT_LTO  LIBRARY

  TSM  SERVER  RMT5  DRIVE  RMT_LTO
  TSM  SERVER  RMT6  DRIVE  RMT_LTO
  TSM  SERVER  RMT7  DRIVE  RMT_LTO
  TSM  SERVER  RMT8  DRIVE  RMT_LTO

Any other ideas comments are welcome!

Thanks
