Migrating data from an SMI-S enabled storage system to another storage system
You can migrate data from an SMI-S enabled storage system to another storage system.
Prerequisites
• Register Tiered Storage Manager license.
• Set up Tiered Storage Manager CLI (if necessary).
• Set up Device Manager CLI (if necessary)
• Connect port on the SMI-S enabled storage system to External port of the storage system via Fibre
Channel.
• Assign the volumes on the SMI-S enabled storage system to External port (performed by the man-
agement tool of the SMI-S enabled storage system).
• Gather the following information:
• Name or IP address of the allocation target host.
• WWN and LUN associated with the migration source SMI-S enabled storage system that was
assigned to the External port.
For details about the specified values specified for parameters and syntax of each CLI command of
Device Manager and Tiered Storage Manager to be used in tasks, see the HP XP7 Command View
Advanced Edition CLI Reference Guide and the Tiered Storage Manager CLI Reference Guide.
1. Register the migration target storage system and the migration source SMI-S enabled storage
system in HP XP7 Command View Advanced Edition. Use the GUI to register the storage systems,
or run 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.
Observe that the following steps (3 - 4) need to be performed while the host is stopped, so you
need a plan that considers host operations.
3. Map the volumes of the migration source SMI-S enabled storage system to the migration target
storage system as external volumes.
Use the GUI to map the volumes or run 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 run the AddLun command (Device Manager CLI).
