The exact error message will be similar to this:

HSCLA27C The operation to get the physical device location for adapter U9119.FHB.1234AB1-V2-C435 on the virtual I/O server partition myvio10 has failed.


This error message can occur for many reasons. Things to check:

a - If this is an inactive migration of an NPIV client LPAR that has not had at least one successful active migration, an inactive LPM will fail as the client wwpns will not have been propagated.

b - All Adapters in the VIO server profile properties tab must be created in a "desired" state (no).

c - ALL adapters assigned to the mobile LPAR MUST be logged in or LPM will fail.

d - LPM requires that all fcs ports that are mapped to the mobile LPAR MUST have a SAN storage device presented to the fcs port. LPM requires that all virtual fcs adapters on the mobile LPAR MUST have at least one SAN disk zoned to the fcs port's primary AND secondary WWPN.

e - SAN Zoning issue, check that the second WWPN is zoned correctly or check that it has logged in correctly. Both of the WWPNs from the virtual fiber channel adapter in the client LPAR's profile properties MUST be zoned the same.
