Do you have a SAN/fiber/iSCSI environment with multiple paths to the
storage? If so, then you can configure multipathing and filtering to
allow LVM to take advantage of the redundant paths to the storage.

If you don't have a multipath environment then you need to figure out
why these two devices seem to have the same content. Could they have
been copied (dd, some clever storage mirroring thingamy? broken (split)
RAID1 mirror?).

Bryn.
