HP Online Import Software manual Example 11 Updating path configuration on the host

11.HP recommends that you change the HP 3PAR host persona/host OS to the appropriate setting before enabling access to the HP 3PAR array.

NOTE: EMC Storage arrays do not implement specific OS settings when registering host initiators on the EMC Storage array. During migration, online import cannot determine the host OS when migrating the hosts to the HP 3PAR StoreServ Storage. All hosts that are being created on the HP 3PAR StoreServ Storage during EMC migration are set by default to host persona 2.

12.Update path configuration on the host. Multipath now recognizes extra paths to the HP 3PAR StoreServ Storage, but all are still managed as source array devices.

a.Rescan.

b.Reload the multipath.conf file.
