Linux does not do reserve/release, so you need to be very, very sure that the devices never come online to more than one LPAR at a time.
I'd suggest a simpler solution: designate one LPAR as a NFS file server and use NFS to mount the volumes on the various other LPARs. It's a lot simpler to manage, and it's a ideal use for hipersockets if you have them. -- db David Boyes Sine Nomine Associates > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Froberg, David C > Sent: Friday, January 09, 2004 11:55 AM > To: [EMAIL PROTECTED] > Subject: LVM usage between lpars > > > Folks, > > Sanity check. > > I've defined two LVM physical volume groups.
