Persistent FCID

[Joseph D. Gifford]

What is HP's official position on LUN failover utilizing Persistent FCID with HP-UX 11i v1 or HP-UX 11i v2? This is a function of the FC switch fabric but I cannot find any documentation from HP on it.

Persistent FCID mode (default setting) is required on all C-series Fibre Channel switches in fabrics or VSANs that include HP-UX or IBM AIX servers, when implementing port-based fabric zoning.
