Hi,
We are in the progress of migrating a 3PAR T400 to a Storserv 7400 using peer motion. In this particular case we saw LUN retry messages on the host and wondered as this is a retry of 3x times that we can be assured no data is affected.
This seemed to occur just as the migration on the storage side was hanging up.
The server is running Solaris 10, the HBA and MPXIO driver stack has been advised as supported.
The host side config has proven to work with the T400.
