LVM High Availability

Does anybody have any experience to contribute about what other LVM systems do in these situations? They don't have the dynamic scan/assignment stuff in Solaris or AIX, right? (Showing my ignorance here).
The logical volume manager in Tru64 (aka Digital Unix, aka OSF/1) from the Q (compaQ) handles high availability by packaging the volumes in disk groups. A given disk group may only be imported into one of the machines on the shared bus. Since this is basically a relicensed Veritas (I think), I expect similar strategies in other environments.

Veritas fails miserable if you are using FCAL, since SCSI reserve is not working on our FCAL. It messed up a 20GB mail spool partion. it's not problem using veritas importing a disk group on 2 machines if you are _not_ using SCSI.
