HP XP Array Manager Software - Manual (Page 55)

Migrating data from an SMI-S Enabled storage system to another storage system
Tasks that must be completed beforehand:
• The Device Manager CLI is set up.
• The Tiered Storage Manager CLI is set up (if necessary).
• The port of the SMI-S Enabled storage system is connected to the External port of the storage system
via Fibre Channel.
• The volumes of the SMI-S Enabled storage system are assigned to the External port (performed by
the management tool of the SMI-S Enabled storage system).
Information that should be obtained beforehand:
• Name or IP address of the allocation target host.
• The WWN and LUN associated with the migration source SMI-S Enabled storage system that was
assigned to the External port.
For details about the values specified for the parameters and syntax of each CLI command of Device
Manager and Tiered Storage Manager to be used for operations, see the HP P9000 Command View
Advanced Edition Suite Software CLI Reference Guide and the HP P9000 Tiered Storage Manager
Software CLI Reference Guide.
To migrate data from an SMI-S Enabled storage system to another storage system:
1. Register the migration target storage system and the migration source SMI-S Enabled storage
system in P9000 Command View AE Suite. Use the GUI to register the storage systems, or execute
the AddStorageArray command (Device Manager CLI).
WARNING!
Note that 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.
Note that 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.
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.
