Sharing devices

[Gary Coffin_2]

I'm looking for a solution to a seemingly simple problem. I want to be able
to share disks and/or tape drives between two HP9000 systems. I currently use
an MS ServiceGuard configuration that allows exclusive access to one machine at
a time. I would like to have both machines be able to read from the same set
of disks at the same time. Any ideas?

Thanks in advance,
Gary

Well it depends on WHY you want to share the discs. Is it for an Oracle
Databse?
If so then consider MC/ServiceGuard OPS Edition.
If not, then I would not recommend activating a VG on two systes at the same
time, and in fact MC/SG specifically prevents this.
As for the tapes, take a look at the Advanced Tape Services that now come with
MC/ServiceGuard.
Allows for sharing specific tape devices between two nodes, using FC/SCSI/MUX
units.
