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:

a.Issue the following command:

symaccess -sid <vmax id> list logins

b.Check the Identifier listed for each HP 3PAR peer port and make sure they are logged in (Yes).

C:\Users\Administrator>symaccess -sid 1212 list logins

•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 -rescanoption, 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.
