5.1.3 Creating a new MAINT minidisk
If you have adequate space to extract the files on the MAINT 500 disk, you can skip this
section. If you received the error
DMSERD107S Disk C(500) is full on the previous step,
creating a new minidisk for MAINT will be necessary. If so, perform the following steps:
1. Create a new MAINT 501 disk for temporary storage of the uncompressed RSU by using
400 cylinders of space taken from the end of the W02 disk (volser is UV6284 in this
example). Verify that the disk layout is good, then bring the changes online with the
DIRECTXA command:
==> acc 2cc c
DMSACC724I 2CC replaces C (500)
==> x user direct c
...
USER MAINT LNX4VM 128M 1000M ABCDEFG
AUTOLOG AUTOLOG1 OP1 MAINT
ACCOUNT 1 SYSPROG
...
* add a new MAINT 501 disk for additional space for service files
MDISK 501 3390 2371 400 UV6284 MR LNX4VM LNX4VM LNX4VM
...
==> diskmap user
...
==> x user diskmap
... // check the report file for gaps or overlaps
==> directxa user
z/VM USER DIRECTORY CREATION PROGRAM - VERSION 6 RELEASE 1.0
EOJ DIRECTORY UPDATED AND ON LINE
HCPDIR494I User directory occupies 45 disk pages
2. Log off MAINT and log back on to load the new directory entry. An attempt is made to
access the MAINT 500 and 501 disks as file mode C and F, respectively. However, the
new 501 disk has never been formatted. Format it and access it as file mode F:
==> log
... // log back on
==> acc 500 c
DMSACC724I 500 replaces C (2CC)
==> acc 501 f
DMSACP112S F(501) device error
==> format 501 f
DMSFOR603R FORMAT will erase all files on disk F(501). Do you wish to continue?
Enter 1 (YES) or 0 (NO).

DMSFOR605R Enter disk label:
mnt501
DMSFOR733I Formatting disk F
Now that a new MAINT 501 disk is available, it can be used to stage the RSU file.
Important: Normally, this step is not necessary. Some RSUs can be so large that they will
not fit on the MAINT 500 minidisk. This is the case with the stacked RSU 5405 for
z/VM V5.4.
