Media Management 4.11 Volumes 4.10.2 Default Users 4.10.3 Threshold 4.11 Volumes Default users are authorized like the authorized users, but in addition are assigned this pool as their default pool. In this case, if they attempt to allocate a volume and don’t specify a pool, they will allocate a volume from this pool. A particular user need only appear in one list: they do not need to be listed in both lists to be an authorized user to their default pool. Pools are useful for dividing volumes between groups or organizations, but they are only useful is there are free volumes in the pool. MDMS provides the capability of monitoring the number of free volumes in a pool. A free volume is one that is available for allocation and writing new data. Many users would like to maintain a minimum number of free volumes in a pool to handle tape writing needs for some period of time. You can specify a threshold value of free volumes, below which an OPCOM message is issued that asks an operator add some more free volumes to the pool. In addition, the color status of the pool in MDMSView changes to yellow if the number of free volumes falls below the threshold, and to red if there are no free volumes in the pool. If you wish to disable threshold OPCOM messages and color status, set the threshold value to 0. A volume is a physical piece of tape media that contains (or will contain) data written by MDMS applications (ABS or HSM), or user applications. Volumes have many attributes concerning their placement, allocation status, life-cycle dates, protection attributes and many other things. Volume records can be created manually with a “Create Volume” operation, or automatically be MDMS with “Inventory Jukebox” and “Load Drive” operations. The MDMS$CONFIGURE command procedure can also be used to create volumes. Once a volume is created it acquires a state. This state determines how the volume may be used at any time, and to an extent where the volume should be placed. The following figure illustrates the life cycle of volumes, and the following table indicates how a volume transitions from one state to another. 4-18 Media Management
