Viewing Migration Status

Viewing all Migrations

To view all migrations, use the showmigration command from the HP 3PAR Online Import Utility.

Viewing Migrations for a Selected Source Storage System

To view all migrations for a selected source EMC Storage system, use the showmigration command with the source option from the HP 3PAR Online Import Utility. All migrations for the storage system are displayed.

Viewing a Selected Migration

To view a selected migration, use the showmigration command with the migrationid option from the HP 3PAR Online Import Utility.

Viewing Selected Migration Progress by Volume

To view details for a selected migration by source storage system volume, use the showmigrationdetails command with the migrationid option from the HP 3PAR Online Import Utility.

Aborting a Migration

A migration can be aborted before it has started by using the removemigration command from the HP 3PAR Online Import Utility. Once a migration has started, it cannot be aborted. To completely remove a migration, the removemigration command must be executed a second time. See “removemigration” (page 80).

Performing Subsequent Migrations

The source EMC Storage system and destination HP 3PAR StoreServ Storage system that have been defined using the HP 3PAR Online Import Utility: addsource/adddestination commands, can remain defined for subsequent migrations. You only need to run the HP 3PAR Online Import Utility addsource and adddestination commands if a subsequent migration will be using a new source or destination storage system.
