The following table shows the meanings of the information displayed.

Title	Explanation
LV No	Displays the logical volume number in hexadecimal.
LV Name	Displays the alias for the logical volume (0 to 32 characters). (Only be displayed when used with an ETERNUS Disk storage system that supports logical volume alias name.)
LV Size	Displays the size of the logical volume in Megabytes.
LV Type	Displays the logical volume type. Open: This refers to an "Open Volume", which means a normal volume that can be used with open systems. FTV: This refers to a "Flexible Tier Volume", which means a hierarchy target volume that can be used with open systems. SDV: This refers to a "Snap Data Volume", which means a volume that can be used as the copy destination for SnapOPC/SnapOPC+. The volume of this type cannot be used as the copy destination for OPC/QuickOPC/EC/REC. TPV: This refers to a "Thin Provisioning Volume", which means a virtual volume that can be used with open systems. WSV: This refers to a "Wide Striping Volume", which means a volume that concatenates multiple RAID groups by striping.
RG No	Displays the RAID group number. The hyphen (-) is displayed, when "TPV" is displayed in LV Type column. When the LV Type column is "WSV", the displayed items are delimited by commas (",").
Encrypt	Displays the encryption status of the logical volume. -: Indicates an unencrypted volume. Yes: Indicates an encrypted volume.
Virtual Size	Displays the virtual size of the Snap data volume in MB if the -l option is specified. If the logical volume type is other than "SDV", a hyphen (-) is displayed.
Copy Inhibit	Displays the volume protection status. The status is displayed only if the -l option is specified. -: The volume is not protected. Yes: The volume is protected. If the logical volume type is "SDV" or the device does not support the volume protection function, a hyphen (-) is displayed.

NOTES

This command is not available for ETERNUS Disk storage system registered as a remote device.
