HPVOLINFO
When the specifier is 1 or 4, the total MPE overhead consists of the MPE
overhead on the volume whose LDEV or volume name was specified. These
are subsets of items 16 and 17.
When the specifier is 2 or 3, the MPE overhead on the volumes that make
up the set or class is returned.
18 & 19 MPE/iX transient space overhead
Returns the MPE/iX transient space overhead. This item is valid only on
MPE/iX.
These are subsets of items 16 and 17.
Item 18 returns a 64-bit signed integer containing the transient space
overhead in sectors. Item 19 returns this overhead as a 64-bit real.
Transient space overhead consists of volume space that is used for
temporary processes, such as stacks, heaps, and the operating system data
structure.
When the specifier is 1 or 4, the transient space consists of the transient
space on the volume whose LDEV or volume name was specified.
When the specifier is 2 or 3, the transient space on the volumes that make
up the set or class is returned.
20 & 21 Configured maximum MPE/iX transient space
Function = MPE/iX: VOLUTIL command
Returns the configured maximum MPE/iX transient space.
These are subsets of items 16 and 17.
Item 20 returns a 64-bit signed integer containing the maximum transient
space overhead in sectors. Item 21 returns this overhead as a 64-bit real.
This is volume overhead that is configured for transient space use. It is not
necessarily used. This is space configured for stacks, heaps, and operating
system structures.
Refer to Items 18 and 19 above.
When the specifier is 1 or 4, the configured maximum transient space
consists of the configured transient space on the volume whose LDEV or
volume name was specified.
When the specifier is 2 or 3, the configured transient space on the volumes
that make up the volume set or class is returned.
22 & 23 MPE V virtual memory overhead
Function = MPE V: SYSDUMP virtual memory device allocation portion (SM
capability required to use SYSDUMP).
Returns the MPE virtual memory overhead. This is valid only on MPE V.
These are subsets of items 16 and 17.
Item 22 returns a 64-bit signed integer containing the virtual memory
