Three GAPs should be listed on the right side:
• 501 cylinders on the $$$$$$ volume
• 1 cylinder on the $$$LNX volume
• 1 cylinder on volume used for LNXMAINT 191 and 192 disks (UM6289 in this example)
You don’t have to worry about the first two gaps as they are expected given the layout of
the default USER DIRECT file. To avoid a 1 cylinder gap being reported on each user
volume, it is recommended to use the user ID $ALLOC$. This user is set to NOLOG which
means it can never be logged onto. Thus it is not a conventional user ID, rather, it is a
convenient place to put dummy minidisk definitions for cylinder 0 of all PERM volumes.
► Get out of the file USER DISKMAP with the QUIT command or by pressing F3.
► Edit the USER DIRECT file again and add a new minidisk definition at virtual address A04 for
the first cylinder of the DASD you added (the label is UM6289 in this example):
==> x user direct
====> /user $alloc
USER $ALLOC$ NOLOG
MDISK A01 3390 000 001 610RES R
MDISK A02 3390 000 001 UV6283 R
MDISK A03 3390 000 001 UV6284 R
MDISK A04 3390 000 001 UM6289 R
► Save your changes with the FILE subcommand and run DISKMAP again. Edit the USER
DISKMAP file. This time you should see just two gaps for volumes with labels $$$$$$ and
$$$LNX. If you search for $ALLOC$ user ID, you should see the disk map of the volume you
added for LNXMAINT:
==> diskmap user
The minidisks with the END option specified in this directory will not be includ
ed in the following DISKMAP file.
File USER DISKMAP A has been created.
==> x user diskmap

► When you are done you can quit by pressing F3.

► Now that you are sure the minidisk layout is correct, the changes to the USER DIRECT file
can be brought online using the DIRECTXA command:
==> directxa user
z/VM USER DIRECTORY CREATION PROGRAM - VERSION 6 RELEASE 1.0
EOJ DIRECTORY UPDATED AND ON LINE
HCPDIR494I User directory occupies 43 disk pages
If the DIRECTXA command fails, correct the problem before proceeding.
You have now defined your first z/VM user ID named LNXMAINT.
