AW: [ADSM-L] Forcing certain nodes to use selective tape drives?
2005-10-07 05:37:15
Hi,
the 3584 tape library can be configured in several logical libraries.The 4 SCSI
LTO1 drives can be configured
in the first logical library with the control path defined on the first SCSI
LTO1 drive. The 4 FC LTO2 drives
can be configured in the second logical library with the control path defined
on the first FC LTO2 drive.
It is possible to configure two libraries within one TSM Server. For each
logical library a deviceclass
and a storagepool has to be defined.
best regards,

Betreff: [ADSM-L] Forcing certain nodes to use selective tape drives?
Can anybody help with the following problem?
I have a customer that currently has a 3584 tape library with 4 SCSI LTO1 tape
drives configured to a AIX TSM 5.1.9 server. They have asked me to add an
additional 4 LTO2 SAN attached drives to the same TSM server / library
configuration. So in essence the one TSM server will now have 8 drives.
The question that I need to answer is this. Is it possible within the one TSM
server to control which client backs up to which drive? The reason that I am
asking this is that the customer wants to split their production backups to go
to the new SAN drives, and their development backups to go to the SCSI drives.
My thoughts are that this is not possible from the one TSM server as TSM will
pick a drive at random if all 8 drives are configured within the same library.
I believe that the only way that this would be possible is to configure two TSM
servers to share the same physical library (once it has been partitioned). Each
TSM server will then be configured with a library a piece, each accessing 4
drives. Backup nodes can then be assigned to the relevant TSM server.
Your comments / experience would be very much appreciated.
Regards
