2. Edit the USER DIRECT file and create three new sections, that is, LINUX02, LINUX03, and
LINUX04. You need to use the DASD volumes you just formatted, with two for each virtual
server. You can repeat the definition of LINUX01 three times with the block copy ""3 prefix
command. For example:
==> x user direct
====> /user linux01
...
""3 *
02142 USER LINUX01 LNX4VM 256M 1G G
02143 INCLUDE LNXDFLT
02144 OPTION APPLMON
02145 MDISK 100 3390 0001 3338 <UM63A9> MR LNX4VM LNX4VM LNX4VM
"" MDISK 101 3390 0001 3338 <UM3F09> MR LNX4VM LNX4VM LNX4VM
3. This will create three more copies of the LINUX01 user definition. Modify them to have a
user ID of LINUX02, LINUX03, and LINUX04, and give each one the correct DASD labels:
USER LINUX02 LNX4VM 256M 1G G
INCLUDE LNXDFLT
OPTION APPLMON
MDISK 100 3390 0001 3338 UM63AA MR LNX4VM LNX4VM LNX4VM
MDISK 101 3390 3339 3338 UM63AA MR LNX4VM LNX4VM LNX4VM
*
USER LINUX03 LNX4VM 256M 1G G
INCLUDE LNXDFLT
OPTION APPLMON
MDISK 100 3390 6677 3338 UM63AA MR LNX4VM LNX4VM LNX4VM
MDISK 101 3390 0001 3338 UM63AB MR LNX4VM LNX4VM LNX4VM
*
USER LINUX04 LNX4VM 256M 1G G
INCLUDE LNXDFLT
OPTION APPLMON
MDISK 100 3390 3339 3338 UM63AB MR LNX4VM LNX4VM LNX4VM
MDISK 101 3390 6677 3338 UM63AB MR LNX4VM LNX4VM LNX4VM

4. Go to the top of the file and find the definition for the $ALLOC$ user. Add dummy
definitions for cylinder 0 of each of the new volumes and save the changes. In this
example, two volumes are added, UM63AA and UM63AB:
====> top
====> /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
MDISK A05 3390 000 001 UM6290 R
MDISK A06 3390 000 001 UM6293 R
MDISK A07 3390 000 001 UM6294 R
MDISK A08 3390 000 001 UM63A2 R
MDISK A09 3390 000 001 UM63A9 R
MDISK A0A 3390 000 001 UM63AA R
MDISK A0B 3390 000 001 UM63AB R
