Volume On an XP array, a volume is a uniquely identified virtual storage device
composed of a control unit (CU) component and a logical device (LDEV)
component separated by a colon. For example 00:00 and 01:00 are two
uniquely identified volumes; one is identified as CU = 00 and LDEV = 00,
and the other as CU = 01 and LDEV = 00; they are two unique separate
virtual storage devices within the XP array.
VSC Volume size customization. Synonymous with CVS. A feature that
defines custom volumes (CVS volumes) that are smaller than normal fixed-
sized logical disk devices (OPEN-x volumes).
XDF Extended distance feature (for ExSA channels).
WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
