Maybe not from 2 separate VGs but they add an additional level to group
PVs together. With HP-UX you can use "lvcreate -m -s g" to use different
PV-groups for the mirror. With Tru64 as far as I know you can use a Plex
to create a PV-group (should be similar with Veritas)

That's an idea, but when I'm adding 4 more disks (eg. disk1 and disk2
from fabric1, disk3 and disk4 from fabric2), how can I tell LVM to
mirror Disk1,2 to Disk3,4 and not to mirror Disk1 to Disk2?
