DISCFREE
Operation

Operation
To invoke DISCFREE enter:
DISCFREE
or
RUN DISCFREE.PUB.SYS;INFO="[format][,ldev]"
or
DISCFREE "[format][,ldev]"
where
format is the specified display type. The format default is A.
ldev specifies a particular system volume. The ldev default is no ldev, causing all volumes to be
displayed.
If you do not specify either of the parameters, DISCFREE prompts for them. If you enter format but not ldev,
DISCFREE reports on all logical disk devices. To report on a particular volume, enter the name of the volume
set. For example, to display information about the volume USER_VOL_SET, you would enter:
RUN DISCFREE.PUB.SYS;INFO=",,USER_VOL_SET"
The format values you can specify are:
Displaying the histogram
To display a histogram for ldev 1 only enter:
DISCFREE "A,1"
To display the histogram for all disk devices enter:
DISCFREE "A"
Or, you may enter the DISCFREE command (without any options) and, at the prompt, enter only the format
and ldev or only the format. For example:
Enter [<format>][,<ldev>] : "A,1"
Enter [<format>][,<ldev>] : "A"
Displaying the allocation summary
To display the allocation summary as a percent of total space on all logical disk devices, enter:
AA histogram showing numbers of blocks by size categories.
B Shows transient and free space allocations in sectors.
C Shows transient and free space allocations in percentage of total device capacity.
D Shows disk allocation summary in sectors.
E Shows disk allocation summary in percentage of total space.
