This verifies that we have recovered one logical partition, which is two physical

partitions (8MB) from the hd6 logical volume, so we can now remove the

temporary paging00 logical volume.

How to Remove a Paging Logical Volume

Now that the smaller hd6 logical volume has been returned to its original

operating conditions, we can follow the process described in the article

Changing or Removing a Paging Space

to remove our temporary logical volume.

To remove the paging device paging00:

1. Follow the procedure given in “How to Change the Attributes of a Paging

Logical Volume” on page 306 to change paging00 so that it will not be active

after a reboot.

2. Reboot the RISC System/6000 by executing the

shutdown -Fr command.

3. When the system is up, login in as root and execute the fast path

smitty rmps

to get to the menu with the title Remove a Paging Space. Alternatively, you

can go through the smit hierarchy by:

a. Executing

smitty.

b. Selecting System Storage Management (Physical & Logical Storage).

c. Selecting Logical Volume Manager.

d. Selecting Paging Space.

e. Selecting Remove a Paging Space to get to the same menu.

4. Press the F4=List to generate a list of paging logical volumes.

5. Use the Arrow keys to highlight the

paging00 logical volume name, and then

press the Enter=Do key three times (once to enter the name in the field,

once to get the warning, and the third time to execute the command).

6. When smit returns an

OK prompt, press the F10=Exit to return to the

command line.

8.8 Common Disk Management and Error Recovery Procedures

This section will show examples of the use of the migratepv and the rgrecover

command and shell script respectively. We also include the contents of the

dsksyn script that many people have used in AIX Version 3, although we did

not

test this script in AIX Version 4.

For further examples of recovery procedures, see Appendix C, “General Volume

Group Recovery” on page 345.
