HP 3PAR Online Import for EMC Storage Data Migration Guide

Create the Data Migration Task
The data migration task identifies the details on the source and destination storage system required
to perform a migration and does the initial preparation required for the data migration:
• On the source storage system, the HP 3PAR initiator is added into a storage group where
host/volumes being migrated are located. The Host Name of the 3PAR initiator is
“UNKNOWN”. The Initiator Name appears as the WWN of the peer port on the 3PAR.
• Volumes are admitted to the destination storage system but are not exported to the Windows
host.
• Creating the migration task does not initiate the data transfer.
To create the data migration task:
1. From the HP 3PAR Online Import Utility, execute the createmigration command.
The command performs the following pre-checks before creating the migration:
• No existing migration task for specified source storage system:
◦ There can only be one migration provisioned at a time per source EMC Storage
system.
• The source storage system group configuration is valid.
◦ The volume(s) or host specified in the createmigration command are mapped
to a storage group on the associated source EMC Storage system. All LUNs and all
hosts in the mapped storage group will be migrated even if only a subset are entered
in the createmigration command. Refer to “Supported and Unsupported
Migrations by HP 3PAR Online Import Utility for EMC Storage” (page 17) to determine
if your configuration is valid.
• EMC SMI-S Provider version.
• Source storage system version.
NOTE: Refer to the Single Point of Connectivity Knowledge (SPOCK) website for the
latest supported versions http://www.hp.com/storage/spock
• LUN migration eligibility:
◦ Protocol must be Fibre Channel.
◦ Replication LUN cannot be migrated.
Example 5 createmigration command
>createmigration -sourceuid 50067890C6E059EE -srchost "HPDL585-01" -destcpg "FC_r5" -destprov thin -migtype
MDM
>SUCCESS: Migration job submitted successfully. Please check status/details using showmigration command.
Migration id: 1395864499741
NOTE: Be aware, the createmigration command may take several minutes to complete.
TIP: Make a note of the Migration ID as it will be used in commands to track migration
progress.
2. Enter 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%) .
