TIP: Make a note of the Migration ID as it will be used in commands to track migration
progress.
2. Execute the showmigration command to verify the data migration task preparation has
completed successfully. This may take some time. On the successful creation of the task the
STATUS column will indicate preparationcomplete(100%).
Example 53 showmigration command
>showmigration -migrationid 1395864499741
MIGRATION_ID TYPE SOURCE_NAME DESTINATION_NAME START_TIME END_TIME
STATUS(PROGRESS)(MESSAGE)

3. Execute the showmigrationdetails command to verify the volumes being migrated. In
the preparation stage, PROGRESS for each volume will be 0% and the TASK_ID will be
unknown.
Example 54 showmigrationdetails command
>showmigrationdetails -migrationid 1395864499741
SOURCE_VOLUME DESTINATION_VOLUME TASK_ID PROGRESS
OIU_Test_Lun_01 OIU_Test_Lun_01 |unknown| 0%
4. 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.

HP 3PAR StoreServ Storage System
To start the migration from the Source EMC Storage system to the destination HP 3PAR Storage
system, follow these steps:
1. From the HP 3PAR Online Import Utility, execute the startmigration command.
Example 55 startmigration command
>startmigration –migrationid 1395864499741
>SUCCESS: Data transfer started successfully
2. To view the status of the migration, execute the showmigration command.
