Appendix C 205
Managing Disk Space
Using the ALTERVOL Command
Using the ALTERVOL Command
Use ALTERVOL to clear additional disk space for use during the modification (patch, add-on,
update, or install) process. The ALTERVOL command sets the percentage of allowable use
for each disk.
CAUTION If you use the ALTERVOL command to increase the allowable percentage of use
for LDEV 1, you MUST return the disk usage percentage back to its original
settings after you perform the system modification. If you do not do this, you
will not be able to reserve contiguous disk space in the future.
1. Log on to MANAGER.SYS.
:HELLO MANAGER.SYS
2. Start VOLUTIL.
:VOLUTIL
3. Show how much of the disk is currently in use. The following is a sample command and
return output.
VOLUTIL>SHOWVOL MPEXL_SYSTEM_VOLUME_SET:MEMBER1 VOLINFO
Volume set index: 1
Maximum permanent space: 75% (3970608 sectors).
Maximum transient space: 75% (3970608 sectors).
Record the values listed in your output. You will need these values later to reset the
disk usage percentage.
4. Set the usage percentage to maximum for LDEV 1, 90%.
VOLUTIL>ALTERVOL mpexl_SYSTEM_VOLUME_SET: MEMBER1 90 10
5. Confirm the change with the system response.
Verify: Set maximum PERMANENT to 90% and maximum TRANSIENT to
10%? [Y/N] _
6. Check the percentage usage again.
VOLUTIL>SHOWVOL mpexl_SYSTEM_VOLUME_SET:MEMBER1 VOLINFO
A typical system response is:
Volume set index: 1
Maximum permanent space: 90% (4764730 sectors).
Maximum transient space: 10% (529414 sectors).
7. Return to the procedure you were working on and continue with the instructions.
8. After completing the system modification, reset the disk space usage percentage back to
the levels found in Step 3. Repeat the steps in this section using the original
percentages.
