Figure 1-1 Flow of Migration Operations

1. Map volumes (LDEVs)

Use the External Storage XP from StorageWorks XP12000/XP10000 to map the volumes (LDEVs) on

external storage subsystems to StorageWorks XP12000/XP10000. Mapping involves determining the

controller LDEV numbers on the domain control storage subsystem, for volumes (LDEVs) on external

storage subsystems. Mapping enables volumes on external storage subsystems to be handled in the

same manner as those on StorageWorks XP12000/XP10000.

2. Create a storage domain

Use the CreateStorageDomain command to create a storage domain. Creating a storage domain

involves registering, as a storage domain in Tiered Storage Manager, a domain control storage

subsystem or a domain control storage subsystem to which external storage subsystems are connected.

Migration (relocation of volume data) can be performed within the storage area consisting of the domain

control storage subsystem and the external storage subsystems that are connected to it.

3. Create a storage tier

Use the CreateStorageTier command to create a storage tier in the created storage domain. A

storage tier is a collection of volumes that are migration target volume candidates. A storage tier is

determined by the filter condition specified for the filtercondition parameter of the

CreateStorageTier command.
