Use NPIV to define virtual HBAs that can then be migrated between
servers. This also makes overall configuration more secure as you can
zone only those servers that need access to these virtual HBAs, so they
can see only own resources.

See documentation for virtual ports in QLogic CLI (scli -vp). Your
switch needs NPIV support too.
