Details on logical volume configuration for Serviceguard, including PV

Sample Fibre Channel Disk Configuration
In Figure 2-7 below, the root disks are shown with simple mirroring, but
the shared storage is now accessed via redundant Fibre Channel
switches attached to a disk array. The cabling is set up so that each node
is attached to both switches, and both switches are attached to the disk
array with redundant links.
