[linux-lvm] alternate pathing with lvm?

[Jos Visser]

The Linux LVM does not currently support alternate pathing (or, as HP
calls it, alternate PV links). LinuxCare did some work on a generic SCSI
alternate pathing feature for the Sun S3 StorEdge arrays (see the
LinuxCare web site for more info on this). I have been giving some
thought to implementing alternate pathing on the "md" level. Basically,
the lower it is implemented in the driver stack, the more generic and
useful it is. I do not know whether alternate pathing is in Sistina's
(or anyone's) roadmap, but it sure would be a cool feature!

We are using several HP MC/SG-Cluster and want to implement an Linux-Cluster with the RadHat Cluster Software too. In the backend there is a HP XP512 and a SAN; the Linuxserver shell be connected to the Storagebox via two FC-HBAs (like the HP servers are). We do not need an online load balancing, all we want is to have a feature for continous work during firmwareupdates, configuration works on FC-switches and so on.
