The server is able to identify multiple storage systems as a single virtual storage machine when the resources listed below are virtualized and the virtual identification (virtual ID) information is set. You can set virtual IDs on resource groups and on individual volumes, as described in the following table.

Virtual information required by the server

Resource on which virtual IDs are set

Serial number

Resource group

Product

Resource group

LDEV ID*

Volume

Emulation type

Number of concatenated LUs of LUN Expansion (LUSE)

SSID

Volume

* A volume whose virtual LDEV ID has been deleted cannot accept I/O from a server. The virtual LDEV ID is temporarily deleted on a volume to be used as a GAD S-VOL because, when the pair is created, the P-VOL's physical LDEV ID is set as the S-VOL's virtual LDEV ID.

When using global storage virtualization you can set the following:

  • The same serial number or product as the virtual ID for more than one resource group
  • Up to 15 virtual IDs for resource groups in a single storage system (VSP 5000 series, VSP E series, VSP F1500, and VSP G1x00)
  • Up to seven types of virtual IDs for resource groups in a single storage system (VSP G/F350, G/F370, G/F700, G/F900)
  • Virtual IDs for a maximum of 1,023 resource groups (excluding resource group #0)
  • Virtual IDs for a maximum of 65,279 volumes

For instructions on setting virtual IDs, see the Command Control Interface Command Reference.
