Advanced Edition Suite Software CLI Reference Guide and the HP P9000 Tiered Storage Manager
CLI Reference Guide.
1. Register the migration target storage system and the migration source SMI-S Enabled storage
system in HP StorageWorks P9000 Command View Advanced Edition Suite. Use the GUI to re-
gister the storage systems, or execute the AddStorageArray command (Device Manager CLI).
NOTE:
Registering or updating a storage system might take a long time depending on its configuration
or scale, so you need to perform these operations systematically.
NOTE:
If the migration target or source storage system has already been registered, you need to update
the migration target or source storage system in order to obtain the latest configuration
information.
2. Stop the hosts to which the storage systems are connected.
Note that steps 3 - 4 below need to be performed while the host is stopped, so you need to make
a plan in consideration of host operations.
3. Map the volumes of the migration source SMI-S Enabled storage system to the migration target
storage system as external volumes.
Execute the AddExternalArrayGroup command (Device Manager CLI).
4. Allocate the external volumes mapped to the migration target storage system to the host.
Use the GUI to allocate the volumes, or execute the AddLun command (Device Manager CLI).
5. Start the host, and then change the target that the host (applications) accesses from the migration
source storage system to the migration target storage system.
Perform this step by using the configuration tools of the host while applications are stopped.
6. Migrate data in the external volumes (migration source) to an internal volume of the migration
target storage system (data migration). Use the GUI to migrate data, or execute the following
commands (Tiered Storage Manager CLI):
•
CreateStorageTier command
• CreateMigrationGroup command
• CreateMigrationPlan command
• CreateMigrationTask command
• ExecuteTask command
7. Unmap the external volumes (migration source) from the migration target storage system.
Execute the DeleteExternalArrayGroup command (Device Manager CLI).
8. Delete the migration source SMI-S Enabled storage system from the management targets of HP
StorageWorks P9000 Command View Advanced Edition Suite.
Use the GUI to delete a storage system, or execute the DeleteStorageArray command (Device
Manager CLI).
The data of the migration source SMI-S Enabled storage system can be used as an internal volume
of the migration target storage system. The migration source SMI-S Enabled storage system can be
removed.
