Another possibility to separate the 3590 and 3592 (in 3590 mode) media is to use a "Manual Tape Library". When you do that, you assign your manual drives to a different SMS Tape Library based on drive type. You then create a Storage Group which refers to the Library Name. In you Storage Group ACS member, you assign (somehow, but could be on UNIT=....) the tape allocation to a Storage Class which then assigns to the Storage Group (and thus to the Tape Library). This restricts the eligible devices to those in that specific Tape Library. And, when the tape is to be mounted again, SMS again restricts the eligible devices to those in that specific Tape Library. In this way, you can have two Manual Tape Libraries to separate your 3952 drives from the 3590 drives. The concept of a Manual Tape Library can also be used if somebody has two separate sets of drives at different locations. Each location would be a separate Tape Library and so tapes created at one location would not be mounted on drives at the other location. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
