Chapter 4. Installing and configuring z/VM 69

7. Release and detach the F disk, CPACCESS the A disk, and verify with the QUERY

CPDISK command:

==> rel f (det

DASD 0CF1 DETACHED

==> cpacc * cf1 a

CPACCESS request for mode A scheduled.

Ready; T=0.01/0.01 09:19:57

HCPZAC6732I CPACCESS request for MAINT's 0CF1 in mode A completed.

==> q cpdisk

Label Userid Vdev Mode Stat Vol-ID Rdev Type StartLoc EndLoc

MNTCF1 MAINT 0CF1 A R/O 610RES D850 CKD 39 158

MNTCF2 MAINT 0CF2 B R/O 610RES D850 CKD 159 278

MNTCF3 MAINT 0CF3 C R/O 610RES D850 CKD 279 398

You have now changed the labels of the system volumes in the SYSTEM CONFIG file. It is critical

that you proceed as your system is now in a state where it will not IPL cleanly.

4.11.2 Modifying labels in the USER DIRECT file

In this section, you will modify the system volume labels in the USER DIRECT file.

Modify the labels in the USER DIRECT file. If you installed z/VM onto 3390-9s, you will need

only the first three CHANGE subcommands:

==> copy user direct c = direwrks = (oldd rep

==> x user direct c

====> c/610RES/MVD850/*

DMSXCG517I 94 occurrence(s) changed on 94 line(s)

====> top

====> c/610SPL/MVD851/*

DMSXCG517I 78 occurrence(s) changed on 78 line(s)

====> top

====> c/610PAG/MVD852/*

DMSXCG517I 117 occurrence(s) changed on 117 line(s)

====> top

====> c/610W01/MVD853/*

DMSXCG517I 2 occurrence(s) changed on 2 line(s)

====> top

====> c/610W02/MVD854/*

DMSXCG517I 1 occurrence(s) changed on 1 line(s)

Traverse the file to view the changes before saving the changes with the FILE subcommand:

====> file

You have now changed the labels of the system volumes in the USER DIRECT and SYSTEM

CONFIG files. Again, it is critical that you proceed with the remaining steps.

4.11.3 Changing the labels on the five volumes

In this section, you will change the labels on the five volumes using the CPFMTXA command.

Four of the five system disks are defined as full-pack minidisks to MAINT as virtual devices

122-124 (610RES, 610SPL, 610W01, and 610W02). If you installed z/VM onto 3390-9s, you

will not need to use 124 and 125. The fifth volume, 610PAG, is defined as the virtual device

$PAGE$ A03. To modify the system volumes’ labels, you will use these virtual addresses.
