Volumes are units of data assigned to storage devices such as the IBM TotalStorage Enterprise Storage and the IBM FAStT Storage Server. Multiple Device Manager (MDM) provides volume management functions, such as creating and deleting volumes and assigning volumes to a host.
Logical volumes are identified in the MDM interface by a volume ID, which is also known as a logical unit number (LUN).
![]() | Note:
The identification number is consistent with whatever convention is used in the native application. For example, an IBM TotalStorage Enterprise Storage Server volume ID is identified by four hex characters (0 - 9 or uppercase A - F). For an IBM FAStT Storage Server, the volume ID is identified as LUN number.
