About virtual storage machinesGlobal storage virtualization provides an abstraction layer between opensystems hosts and storage systems. This layer enables non-disruptive
storage management, such as:
• Non-disruptive host access to global-active device volumes which consist of a P-VOL and an S-VOL that reside on different storage systems.
• Non-disruptive host volume data migration from a source volume on an existing storage system to a target volume on a new storage system.
The features described above...

In the example configuration, the virtual storage machine is created usingthe model type and serial number of the Virtual Storage Platform G1000. Resources from the resource pool of the default virtual storage machine are
added to the user-defined virtual storage machine. The resources are added to the VSP-11111-Pool resource pool. When Resource Group B is created on
the virtual storage machine, resources from the VSP-11111-Pool are added.
Identify the target resources by verifying the correlation...

1.Hosts use the SCSI Inquiry command to determine storage and device
information for accessing volumes.
2. Host I/O is performed with this information.
3. During global-active device setup, the default virtual storage machine of
the Primary storage is edited to include secondary storage system
resources.
4. During volume allocation global-active device copy pairs are created and
the virtual LDEV ID is mapped to the LDEV ID of the S-VOL. The virtual
storage machine information is used to support data...

During the three stages of data migration, accessing the information changesfrom using physical to virtual information.
• Before data migration (using physical information) Before data migration, a host uses physical information to access the
migration-source resources.
• During data migration The path from the host to the storage system is changed from themigration source to the migration destination. Configure virtual
information on the migration-destination resource, and then migrate the data from the...

• To manage copy pairs, such as global-active device pairs by using theresources of a virtual storage machine, review the prerequisites for systemconfiguration. For details, see the  Hitachi Command Suite Administrator
Guide .

• If a DP pool volume is registered to a virtual storage machine, othervolumes that compose the DP pool are automatically registered to the
same virtual storage machine.
