Performing Routine Disk Operations
A list of all existing subvolumes on the disk of your default subvolume is
displayed. This list can help you determine the names of subvolumes that might
need to be purged.
c. Generate a DSAP report showing all subvolumes owned by a given user:
> DSAP $disk, BYSUBVOL, USER group-id,user-id
d. Determine the ages of files in a given subvolume:
> VOLUME subvolume-name
> FILEINFO
A listing of all files contained within the given subvolume is displayed on your
home terminal. The date of the most recent change to each file is shown in the
column named "Last Modification."
e. Consult with the user's manager to determine whether you should purge any
files. Your ability to purge files depends on file security settings; you might
need to change file security if you are authorized to do so, or you might need to
contact your operations manager or database administrator.
2. Purge the files or subvolumes you have determined are old.
To purge a single file within a given subvolume, enter:
> PURGE subvolume.file
To purge an entire subvolume, enter:
> FUP PURGE subvolume-name.*
Example
1. Generate a DSAP report that lists all the subvolumes on $DATA1 owned by the user
SALES.BONNIE, the amount of disk space they occupy, and the number of days
since the subvolumes have been modified and opened:
> DSAP $DATA1, BYSUBVOL, USER SALES.BONNIE
