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 5 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.
For reference, following are the entries in the USER DIRECT file:
...
USER $PAGE$ NOLOG
MDISK A03 3390 000 END 610PAG R
..
MDISK 122 3390 000 END 610SPL MR
MDISK 123 3390 000 END 610RES MR
MDISK 124 3390 000 END 610W01 MR
MDISK 125 3390 000 END 610W02 MR
...
Perform the following steps:
► Use the CPFMTXA command to relabel the 5 system volumes (you will only need the first
three if you installed onto 3390-9s). Be sure to watch for a return code of 0 on each
command:
==> cpfmtxa 123 mvd850 label
...
==> cpfmtxa 122 mvd851 label
