Return to the ISL prompt. Enter the following to start the system
from the disk:
ISL> START NORECOVERY
When the system is up, log on as MANAGER.SYS:
:HELLO MANAGER.SYS
Run the VOLUTIL utility to gain access to the
SHOWUSAGE command:
:VOLUTIL
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:
VOLUTIL> EXIT
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."
