I was always under the impression that a single volume group can only be
made available to a single system. This is where the import volume group
and export volume group features of Veritas and other LVM tools come from.
I know that disks can be made visiable to more than one system, this is
where HA comes in. However, in the event of a failure most HA solutions
will perform the necessary force import functions on a volume group before
fully taking advantage of them.
Am I mistaken here?

Subject: LVM usage between lpars
Folks,
Sanity check.
I've defined two LVM physical volume groups. I plan to share these two
volume groups between three lpars running Linux (SLES 8). The physical
volume groups will provide two pools of space from which logical volumes
can
be allocated and mounted to the various Linux images. (Any given logical
volume will be mounted exclusively to only one Linux image.)
This should not be a problem sharing physical volume groups, correct? I
should be able to share the physical volume groups, right? Are there any
obvious problems with this?
Thanks in advance for any input.
Dave
