HPVOLINFO - New Volume Intrinsic 

by Lalitha Pejavar--Commercial Systems Division 

The new volume intrinsic HPVOLINFO provides a way to retrieve volume
information about both system and nonsystem volumes (on MPE V/E,
nonsystem volumes are equivalent to private volumes).  The volume
information that is returned can be used to track volume space usage.
More specifically, the information that is returned describes how the
space on volumes is allocated i.e., how much is used for operating system
purposes, how much space is free space, how much space is used for spool
files, etc.  Also, with this information, volume fragmentation and lost
disc space information can be determined.  With this intrinsic, the trend
of volume usage can be observed so that future disc needs can be
predicted.  This intrinsic is supported on both MPE V/E Version G.03.10
and MPE XL Release 2.2 and later.  No special capabilities are required
in order to use the HPVOLINFO intrinsic.

The term volume used throughout this article refers to any disc that is
logically mounted on the system.  For example, a disc pack that is
mounted on a disc drive.

This intrinsic can be used to retrieve any of the following information:

 *  Drive type
 *  Capacity of a volume
 *  Sector size of a drive
 *  Amount of volume space used by MPE
 *  Spool file space usage
 *  Permanent and temporary file space usage
 *  Volume type
 *  Volume set name
 *  Number of volume classes
 *  List of volume classes
 *  Ldev that a volume is configured on
 *  Free space information
 *  Number of member volumes
 *  List of member volume names
 *  Number of volume sets
 *  List of volume sets
