Return to the
ISL prompt. Enter the following to start the system from the disk:
When the system is up, log on as MANAGER.SYS:
Run the VOLUTIL
utility to gain access to the SHOWUSAGE
command:
Enter the following SHOWUSAGE
command to identify files with extents on LDEV 1:
VOLUTIL> SHOWUSAGE 1 60000 NONRESTRICT SUMMARY;PERM;FREE |
This command displays the groups of files that can be removed
from LDEV1 and the total amount of contiguous disk space you can
reserve by removing those files.
In the command, the 1 indicates the logical device on which
the volume to be examined is mounted. The value 60000 is the amount
of contiguous disk space that is needed (in sectors). You can use
the estimated amount or run CHECKSLT
to determine how much contiguous disk space is required to update
your system. Refer to "Estimating Disk Space"
in Chapter 3 “Planning for Your Task”
The NONRESTRICT option displays
only those files that are not restricted to this volume. The SUMMARY
option displays that are associated with permanent space.

 | NOTE: SHOWUSAGE may list
more than one group of files that can be purged. Select one group
in the list and store then purge
that group to locate the required number of sectors. |
|
| |
|
Exit VOLUTIL:
Store and purge the selected group of files:
:FILE T;DEV=TAPE
:STORE file.group.account,file1.group.account;*T;PURGE;SHOW |
|
| |
|
| NOTE: If you used SHOWUSAGE
and still have trouble creating this disk space, contact your support
representative. |
|
| |
|
When you have the required amount of contiguous
disk space, build an empty file in PUB.SYS
to reserve the space:
:BUILD AXLDEV1.PUB.SYS;DISC=n,1,1;DEV=1 |
Where n is the amount of contiguous
disk space required on your system.
Refer to "Determining Available Disk Space"
earlier in this Appendix to determine if you have enough disk space
to continue with your task.
If you do have enough disk space, return to the procedure
you were working on and continue with the instructions.
If you do not have enough disk space, proceed to "Using
the ALTERVOL Command."
