NOTE: Having multiple paths to an NPIV device through the same physical HBA port on the VSP

does not fetch the benefits of multi-pathing because all paths will be using the same physical port

for IO traffic and thereby not provide any redundancy.

All aspects of native multi-pathing for regular FC device on a physical host is applicable to an

NPIV device seen in the guest. For more information about native multi-pathing on HP-UX, see

Native Multi-Pathing for Mass Storage technical white paper at

http://www.hp.com/go/hpux-hpvm-docs.

7.5 Migrating VM guests with NPIV HBAs

vPars and Integrity VM 6.1.5 and later versions support online migration of VM guests and offline

migration of vPars and VM guests with NPIV HBAs across an FC fabric. After the migration, the

NPIV HBAs of a particular guest might not always be spread across different pFCs ports or adapters

on the target host. For more information about the modified behavior, see Section 12.3.4.4

(page 213).
