8. IMPORTANT:
• Re-run a scan on the host systems to discover the new volume.
• Verify that the host paths to the destination system are active.
• On fabric, remove zone Z3 and add zone Z4 upon successful preparation completion.
9. startmigration –migrationid <migrationid>
10. showmigrationdetails –migrationid <migrationid>.
This completes the successful flow of the migration.
The following optional commands are to be used to remove the added source and destination
storage systems:
1. removesource -uid <uid> -type 3par
2. removedestination -uid <uid>
NOTE: Removing a source/destination storage system also removes the migration history for the
respective source/destination storage system.
Single VV Migration
The –singlevv option can be used to migrate a subset of volumes provisioned to a host. In this
case, there is no need to unzone the source array from the host that is being migrated.
In order to use single vv migration, the following conditions must be met:
• Both the source and destination arrays must be running at least HP 3PAR OS 3.1.3.
• The host(s) to which the volumes are exported to must be defined using an ALUA persona on
both source and destination storage systems.
To perform SingleVV migration, follow the steps and execute the commands in the following order:
1. addsource -mgmtip <ipaddress> -user <username> -password <password>
-type 3PAR
2. showsource
3. adddestination -mgmtip <ipaddress> <username> -password <password>
-type 3PAR
4. showdestination
5. showconnection
6. createmigration -sourceuid <sourceuid> -srcvolmap
[{"<volumename>","<destinationprovisioning>","<destinationCPG>"}]
-migtype online -singlevv
7. showmigration -migrationid <migrationid>
NOTE: In case there is a need to abort the prepared migration, use the removemigration
command for the same: removemigration -migrationid <migrationid>.
8. startmigration –migrationid <migrationid>
9. showmigrationdetails –migrationid <migrationid>.
This completes the successful flow of the migration.
The following optional commands are to be used to remove the added source and destination
storage systems:
1. removesource -uid <uid> -type 3par
2. removedestination -uid <uid>
