Monitoring Disk Space
DISCFREE is a utility that you can use to determine the amount of free
space on a disk. You can enter any of the following commands to invoke
the DISCFREE utility:
* DISCFREE
* RUN DISCFREE.PUB.SYS;INFO="[format][,ldev]"
* DISCFREE [format]
Format values include the following:
A Shows 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.
The DISCFREE utility provides five types of reports:
* Histogram
* Allocation
* Allocation format 2
* Summary
* Summary format 2
To monitor your disk space
Enter:

To skip the copyright statement and the above prompt, enter a format
value with the command as follows:
DISCFREE A
To see distribution of disk space
To see the distribution of disk space with blocks of contiguous space
(blank sectors that are adjacent to each other), use format value A. The
resulting histogram groups these blank sectors according to size.

To free disk space by creating a tape
If there is not enough free space on the disks, you create space as
follows. Create a tape of the existing spoolfiles and delete the
spoolfiles from the system.
1. Enter:
FILE BACKUP;DEV=TAPE Return
STORE @;OUT.HPSPOOL;*BACKUP;PURGE;SHOW Return
FILE BACKUP;DEV=TAPE defines a file named "BACKUP" in class
"TAPE". STORE @.@ outputs files for all users and accounts, and
PURGE removes the spoolfiles from the system once each has been
copied to the tape.
2. Mount the tape and reply to the tape request.
The system displays the data for each file as it is written to the
tape:
________________________________________________________________________
| |
| |
| #FILE #JOB DEV/CL SECTORS OWNER |
| |
| #0379 #J9 LP 100 MANAGER.SALES |
| #0451 #J2 LP 40 MANAGER.SALES |
| #0453 #J3 LP 40 MANAGER.SALES |
| #0454 #J4 LP 40 MANAGER.SALES |
| #0455 #J5 LP 40 MANAGER.SALES |
| #0456 #J6 LP 144 MGR.TEMPACCT |
| |
________________________________________________________________________
3. Verify that all files were purged from the system by entering:
LISTSPF @ Return
If no spoolfiles are listed, all the files were purged. Remove
the tape from the tape drive and label it.
