OK it's Friday I have to ask you Gordon: What's an IBM SE?

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.

yes you can, no you shouldn't.
how are you going to ensure the integrity of your data if two SLES zLinux
are going after the same data?
even if you mount read only, you'll never know what is being handled in
cache versus on disk.

Hi,all
I'm very in troubled.
Please teach me.
I want to use shared DASD.
The DASD(ADDRESS:1000) is used by two SLES9s.
SLES9s are running on different z/VMs.
(One SLES9-A is running on z/VM-A, the other SLES9-B is
running on z/VM-B.)
Firstly, can I do above scenario?
Thank you
