Figure 4-16 <strong>The</strong> problem with two z/<strong>VM</strong> systems with identical volume labels<br />
In previous books a REXX EXEC and an XEDIT macro were provided to help in the process<br />
of relabeling system volumes. However, if you followed the previous steps, you will have only<br />
one standard label, 6<strong>10</strong>RES. <strong>The</strong> EXEC and macro are no longer provided because they relied<br />
on standard labels. However, high level steps are still included. If you modified all labels<br />
except <strong>for</strong> the first one at install time, it is usually not necessary to per<strong>for</strong>m the steps<br />
in this section.<br />
If you do need to relabel the system volumes, per<strong>for</strong>m the following steps:<br />
► “Modifying labels in the SYSTEM CONFIG file” on page 65<br />
► “Modifying labels in the USER DIRECT file” on page 67<br />
► “Changing the labels on the five volumes” on page 67<br />
► “Shutting down your system and restarting it” on page 68<br />
Important: This process must be done as documented. Making a mistake in one of the<br />
steps can easily result in an unusable system. Check your steps carefully and your system<br />
will come back with no problems. Try to do all steps in succession in a short amount of<br />
time. Close your door, don’t answer your phone or e-mail, turn off instant messaging :))<br />
4.11.1 Modifying labels in the SYSTEM CONFIG file<br />
An HMC Integrated 3270 Console session will be needed in this section because z/<strong>VM</strong> will<br />
have to be restarted with a FORCE option.<br />
► Start a 3270 session. It can be an 3270 emulator session <strong>for</strong> now, or all of the steps can<br />
be done from the HMC.<br />
► Note the first five CP-owned volumes using the QUERY CPOWNED command. In this example<br />
they are D850-D854:<br />

► To modify the labels in the SYSTEM CONFIG file, begin by releasing the A CP-disk and<br />
access it read-write. Back up the SYSTEM CONFIG file:<br />
