2. Now that the five volumes have been relabeled (this is sometimes called “clipping the
volumes”, which is derived from a contraction (clp) of the z/OS term change label
program), you can run the DIRECTXA command to update the directory:
==> directxa user
z/VM USER DIRECTORY CREATION PROGRAM - VERSION 5 RELEASE 4.0
EOJ DIRECTORY UPDATED
HCPDIR494I User directory occupies 43 disk pages
Ready(00005); T=0.01/0.01 15:45:51
A return code of 5 is expected because the labels in the USER DIRECT file are different from
the spool data in the currently running system.
Finally, you are ready to issue a SHUTDOWN command.
4.11.4 Shutting down your system and restarting it
You will need an HMC console session for this step, if you are not already running from there.
To test the changes, you must shut your system down and then restart it. You cannot do a
SHUTDOWN REIPL in this situation because you will have to do a FORCE start
==> shutdown
SYSTEM SHUTDOWN STARTED
HCPSHU960I System shutdown may be delayed for up to 210 seconds
Perform the following steps to bring the system back up:
1. Open an HMC session.
2. Select your LPAR.
3. Use the circular arrow racetrack buttons to get to the CPC Recovery (or just Recovery)
menu.
4. Double-click the Integrated 3270 Console menu item. A new window should appear.
5. Double-click the LOAD menu item. The Load Address (D850, in this example) and Load
Parameter (SYSG) fields should be correct from the previous IPL.
6. Select the Clear radio button. The Load Address and Load Parameter fields should be
correct from the previous IPL. Click OK.
7. Click Yes on the Load Task Confirmation window.
For 3390-9s: The LBL540-9 EXEC should be used for systems installed onto 3390-9s.
For example, if the system volumes are 9300-9302, the command to relabel the system
volumes would be as follows:
==> lbl540-9 <9300 9301 9302>
The volumes are:
DASD 9300 CP OWNED 540RES 142
DASD 9301 CP OWNED 540SPL 2
DASD 9302 CP OWNED 540PAG 0
The system volume labels will become:
MV9300 MV9301 MV9302
ARE YOU SURE you want to relabel the DASD (y/n)?
