Sample Fibre Channel Disk Configuration
In Figure 2-4, 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.

This type of configuration uses native HP-UX or other multipathing
software; see “About Multipathing” on page 47.
