Re: Duel tape write to LTO's

You should be able to create a PRIMARY STGPOOL named TAPEPOOL and a
COPY STGPOOL named COPYPOOL with both of them having a sequential access
(tape) DEVICE CLASS such as DLT or LTO. Both stgpools can be in the
same library. On the stgpool TAPEPOOL definition you set the
COPYSTGPOOLS parameter to COPYPOOL. Then when your client backs up to
TAPEPOOL, TSM will simultaneously write to COPYPOOL. Of course having
an adequate number of tape drives is required.

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
