Morning all

Running TSM 5.1.6.2 on Solaris.

At present I am running the TSM server on a Sun E250 server with 4 internal
17GB disks. Two of them are used for the OS ( software mirrored ) and the
other two are used to house the TSM database and log volumes ( using TSM
mirroring ). At the moment the database is 75% utilised and I don't have
much free space to expand it if necessary. However, I do have a couple of
free disks in an attached A1000 array ( which also houses our 50GB RAID5
backup pool) and I was thinking of creating a new db volume and mirror on
these. Is there any reason why this may be a bad idea i.e. having some
parts of the db on internal disks and some on the array. Will I see
degraded performance because of this etc?

Thanks in advance for any advice
