OK it's Friday I have to ask you Gordon: What's an IBM SE? David Wolfe, Gordon W wrote: >In certain circumstances, sharing a limited amount of dasd read-write among LPARs is possible using hardware reserve/release. We do this with our shared tape catalog in VM:Tape (which is on its own real 3390 with its own controller separate from our regular DASD.) However, it is NOT useful if there is more than just a little I/O to the volume. It will lock up the volume(s) in question faster than anything if there is lots of I/O. It also opens up a can of worms and I do not recommend it unless you really really know what you're doing. We had lots of help from IBM, STK and Systems Center (before it was Sterling, before it was CA) in setting it up for VM:Tape and our STK tape silos. I'm not going to stick my neck out and advise you on how to do it in an e-mail without knowing your system or what you're trying to accomplish. If you're really interested, seek help from your IBM SE. > >"A statesman is a dead politician.
