DASD 63AA FR63AA , DASD 63AB FR63AB
► Attach the volumes to MAINT using the * wildcard:
==> att 63aa-63ab *
63AA-63AB ATTACHED TO MAINT
► Invoke the CPFORMAT command against these volumes using the parameter as perm:
==> cpformat 63aa-63ab as perm
...
DASD status after:
TargetID Tdev OwnerID Odev Dtype Vol-ID Rdev StartLoc Size
MAINT 63AA MAINT 63AA 3390 UM63AA 63AA 0 10017
MAINT 63AB MAINT 63AB 3390 UM63AB 63AB 0 10017
► Detach the seven volumes from MAINT with the DETACH command:
==> det 63aa-63ab
63AA-63AB DETACHED
► Attach the newly formatted DASD to SYSTEM so they can be used for minidisks:
==> att 63aa-63ab system
DASD 63AA ATTACHED TO SYSTEM UM63AA
DASD 63AB ATTACHED TO SYSTEM UM63AB
The volumes will now be available to be used for minidisks in the USER DIRECT file. They will
also be available after the next IPL because their new labels match the pattern specified by
the User_Volume_Include UM* statement in the SYSTEM CONFIG file.
9.2 Defining a new user ID for a virtual server
In this section you will define a new user ID, LINUX01, in z/VM and clone the golden image to
it. To do so, perform the following steps:
► Logon to MAINT and edit the USER DIRECT file to add more Linux ID’s.
==> x user direct c
► Go to the bottom of the file and add the following five lines. In this example the user ID will
be LINUX01 with a password of LNX4VM. It will default to have 256MB of memory but can be
set up to 1GB. It will have only G permission (General user) It will have two 3338 cylinder
(about 2.2 GB each) minidisks. In this example, they are located at device addresses 63A9
which was formatted and given a label of UM63A9:
USER LINUX01 LNX4VM 256M 1G G
INCLUDE LNXDFLT
OPTION APPLMON
MDISK 100 3390 3339 3338 UM63A9 MR LNX4VM LNX4VM LNX4VM
MDISK 101 3390 6677 3338 UM63A9 MR LNX4VM LNX4VM LNX4VM
► You may need to add the new volumes to the $ALLOC$ user ID so cylinder 0 won’t show up
in the disk map as a gap.
► Again check for gaps and overlaps. You can use the ALL subcommand with the logical OR
operator “|” to check for both strings. You should see only one 501 cylinder gap.
==> diskmap user
==> x user diskmap
====> all /gap/|/overlap/
