starter Systems Step 22. Format the MAINT User's Virtual 191 Disk
Initialize the 191 disk belonging to "lINT, in the same way you
initialized the operator's virtual 191. Log off the system and log on
again as userid "lINT, using the password CPC"S. Define your virtual
storage to be larger than the location of any discontiguous saved
segments that C"S may try to use at this time. (In this example, if you
used the D"KSNT provided with the starter system, define your virtual
storage as 2048K, or 2M). Then IPL C"S as follows:
define storage 2m
ipl 190 parm seg=null When the CMS Ready message is displayed, issue:
access (nodisk
and continue to format M1INT's 191, using the same procedure you used to
format OPR191. Step 23. Complete the Application of Service
Now that the M1INT 191 minidisk is formatted, you (as the "lINT user)
can complete the application of service with the changes supplied on the
system program Update Tape (PUT). Mount the system PUT if it is not
already mounted. You must attach the real tape drive to your CMS virtual
machine ("AINT); for example:
attach 280 to maint as 181
and, with the 191 minidisk that belongs to "AINT accessed as your
A-disk, rewind and load the tape:

A1 11 A1 END-OF-TAPE To resume the application of service started in Step 13, issue the
commands:

256 IBM VM/370 Planning and System Generation Guide

Starter Systems VMSERV remaps the PUT because the 191 disk of MAINT is new and does not
contain the previously created map. You are prompted for various
information concerning your system (including staging area addresses and
the service that you want applied). Respond 'NO' when asked if you want
service for RSCS. Service for RSCS is applied when RSCS is installed.
The "Memo to Users" and the PUT document should be referenced concerning
the application of service with the VMSERV EXEC.
Any further SCP service not applied in Step 13 is applied at this
time (including service for CMS and IPCS). VMSERV prompts you with: DO YOU WISH TO CONTINUE APPLYING SERVICE? (YESINO) Respond "No". The following messages are displayed:
hh:mm:ss NO FILES PURGED SYSTEM LOAD DECK COMPLETE hh:mm:ss PUN FILE nnnn TO MAINT COpy 01 NOHOLD hh:mm:ss REWIND COMPLETE WHEN THE NEW CMS SYSTEM IS BUILT ISSUE: I CLOSE PRT' ...... (PRINTS THE LOAD MAP) At this point, the CMS nucleus is loaded via IPL from your virtual
card reader. When the new CMS nucleus is loaded, control passes to
module DMSINI, which then prompts you to specify where to save the
nucleus, what your CMS system residence address is to be, and so forth.
In the following example, the 190 you enter is the 190 minidisk that
belongs to the user MAINT; it is equivalent to the 190 minidisk that
belongs to CPGEN on the starter system. For instance, you specify
cylinder 108 as the nucleus cylinder address for a 23141 when responding
to message DMSINI609R. The 19E you enter is the address of a user disk that may contain any
user-written programs that run under CMS. If you enter a null line when prompted for version identification and
installation heading, CMS uses its own defaults.

volume is updated with the most current object modules (text decks) and
load modules, and the new CMS nucleus is written on the CMS system
residence volume.
If there are any updates for the system assembler on the PUT, the
procedure updates that program and creates the corresponding new
auxiliary directory.
1The nucleus will reside on the last cylinder(s) of the minidisk 190. See the notes in the figures showing the allocation of the starter
system volumes when the starter system directory is used to determine
which nucleus cylinder address to specify. Part 3. Generating VM/370 (CP, CMS, RSCS, and IPCS) 251
