HP Stage/iX Commands

DISKUSE (DU)
The DISKUSE command can be used to determine how much disk space is currently being used by an HP
Stage/iX staging area.
When a staging area is currently in use, the files that are normally in that staging area have been renamed
into their natural locations. As a result, a staging area is virtually empty when it in use (only a few HP
Stage/iX specific files remain). The DISKUSE command is misleading when a staging area is currently in use,
since it cannot account for the disk space used by the files which have been renamed. The DISKUSE command
prints a warning if you do a DISKUSE on the currently active staging area.
The DISKUSE command in STAGEMAN is really just an interface into the MPE/iX DISKUSE command. The
output is therefore identical to the MPE/iX DISKUSE command. For additional information on the MPE/iX
DISKUSE command, use the MPE/iX help facility. This can be done with STAGEMAN by typing:
:HELP DISKUSE
The DISKUSE command can be abbreviated DU.
Syntax
DISKUSE [STAGE=]stage_name
Parameters
[STAGE=]stage_name (required)
This parameter designates which staging area will be displayed. The staging area name must be a valid HP
Stage/iX staging area name. STAGEMAN will use this name to construct the full path name for the directory
where the staging area is kept.
Example
To determine the disk space used by staging area “stage_area_5”:
STAGEMAN> DISKUSE stage_area_5
SECTORS
TREE LEVEL DIRECTORY
147888 147856 /SYS/hpstage/stage_area_5/
DO
The DO command is used to re-execute a command from the command history stack.
Syntax
DO [COMMAND=]command_id
Parameters
command_id:
The command from the redo stack which we want to re-execute. The command may be specified by its relative
or absolute order in the command line history stack, or by name (as a string), in whole or in part. The default
-1 is the most recent command. This parameter is optional.
Example
To re-execute a command by its absolute order in the command line history stack, enter:
STAGEMAN> DO 5
