PV Links (Alternate Paths)
Physical Volume Links (PV Links or Alternate Links) are a High Availability Feature of
LVM which allows to configure multiple links (HW paths) to the same PV for
redundancy. One of them is considered as the primary link while the others act as
alternate links. If LVM detects the primary link beeing unavailable as a consequence of
a failure (e.g. of a SCSI/FC card/cable) it re-routes IO traffic to the first available
alternate link.
