I've been assigned to take over administration of our Tivoli environment, and the biggest problem I see is that we only have 4 tape drives in our tape vault. I'm trying to make tape usage as efficient as possible, since its the most scarce resource in the system, so I'm examining how much dead time the drives are experiencing. So here's my question: when Tivoli finishes a tape operation, does it force the tape drive to keep the tape mounted until the end of the mount retention period, or will it release the drive for another process if there's one waiting for a tape drive? I'm concerned that our tape drives are always in high demand, but are spending 5 minutes sitting idle between jobs ( our mount retention time is 5 minutes). Any help would be great.
