Resource Group Name (ID)

Resource group name and identifier of the LDEV.

Expanded Space Used¹

Displays the information that LDEV is allocated in the expanded area or the physical area. If the accelerated compression is enabled, LDEVs are initially allocated in the physical area, then LDEVs are allocated in the expanded area.

This item displays whether the LDEV area is allocated in the expanded or physical area.

Yes: LDEV is allocated in the expanded area.

No: LDEV is allocated in the physical area.

Virtual Storage Machine¹

Information about the virtual storage machine.

• Model / Serial Number¹: Model name and serial number of the virtual storage machine that has LDEV.
• LDEV ID¹: Virtual LDEV ID. If a Virtual LDEV ID is not assigned to the LDEV, this column is blank.
• Device Name¹: Virtual device name, which is a combination of the virtual emulation type, virtual LUSE volume number, and the virtual CVS attribute. Values of the virtual emulation type, virtual LUSE volume number, and virtual CVS attribute appear only for items that have been set. This column is blank when the virtual emulation type, virtual LUSE volume number, and virtual CVS attribute are not set. If the virtual CVS attribute is set, CVS is attached as the suffix to the device name.
• SSID¹: Virtual SSID. If Virtual SSID is not set for LDEV, this column is blank.
• Attribute¹: Virtual LDEV attribute. If the attribute is not set for LDEV, this column is blank.
