A on the EMC, and zone the peer port on node 1 on the HP 3PAR StoreServ Storage system
to controller B on the EMC Storage system.
3. Verify that the EMC Storage system can detect both ports on the HP 3PAR StoreServ Storage
system.
Ensure that the peer port WWNs appear in the discovered port list.
• To check peer port connections using VMAX, follow these steps:
Issue the following command:
symaccess -sid <vmax id> list logins
a.
b. Check the Identifier listed for each HP 3PAR peer port and make sure they are
logged in (Yes).

• To check the HP 3PAR peer port using VNX or CLARiiON CX4, open the Host tab, open
the Initiator tab, and verify that the initiators are logged in.
Alternatively, verify that the EMC is shown as a connected device on both peer ports of the
destination HP 3PAR StoreServ Storage system.
• To check peer port connections from the HP 3PAR StoreServ Storage, issue the
showtarget command with the -rescan option, and then issue the showtarget
command.
In this example, Node_WWN is the WWN of the source array
# showtarget -rescan
#
# showtarget

Preparing the Host for MDM
NOTE: This section describes preparing the host for MDM. If you are performing a Linux online
migration, see “Performing Online Data Migration Using Linux” (page 40). If you are performing
an offline migration, see “Performing Offline Data Migration” (page 66).
To prepare for a successful migration:
• Stop all applications on the host that may be accessing the LUNs to be migrated. This also
includes any replication and backup applications on the LUNs.
• Set the LUNs to be migrated to an offline/unmounted state.
