General Information
Generating CP and CMS Using the Starter
Systems
Except where otherwise noted, you can sUbstitute other values in place
of the device addresses, volume labels, and allocations shown. Note
that if you use the sample DMKSNT and DMKSYS files provided with the
starter system, and the sample allocations shown in Steps 2 and 3, you
can save your CMS system at the end of the procedure.
It is recommended that you use the sample allocations given
in Step 2 and the label VMRELn for the new system residence volume, to
ensure that you have sufficient TEMP space to complete the system
generation. (The TEMP space provided on the starter system volume may
not be sufficient for large systems.)
The examples of messages and responses assume that you are performing
the system generation at a typewriter terminal, such as a 3210, 2141, or
3767 (operating as a 2141). If you are using a display device, such as
the 3277, when you type the response to a prompting message, that
response appears in the user input area. When you enter that response,
it is redisplayed in the output area on the line below the prompting
message. Also, if the standalone service programs (such as the DASD Dump
Restore program or Format/Allocate program) send output to a terminal
display screen, the output is wrapped around immediately, when the
screen becomes full, to continue displaying. While you are generating the system, you may see some extraneous
messages as the starter system is processing. These are not shown in
the examples below. Only those messages that you should take note of,
or respond to, are shown. Step 1. load the Format Program from the Starter System Tape
Mount the CP starter system tape and IPL the tape. The CP Format/Allocate service program is the first file on the tape; it is now
loaded. Do not rewind the tape because the next file is needed later in
the system generation procedure (Step 4). Step 2. Format, label, and Allocate the System Residence Volume Use the CP Format/Allocate program to format, label, and allocate space
on the new system residence volume. This label must be VKRELn; where n
is the release level of the VM/370 System control program. VMRELn is
used in the starter system's system control file - SYSOWN marco -to
allow the volume to be used for paging, spooling, and TDSK allocations.
First, identify the system console by pressing the Request key (or
equivalent); if the console address is either 009 or 01F, you do not
have to press the Request key. Then, to execute the Format/Allocate
service program, respond to the prompting messages. Part 3. Generating VM/370 (CP, CMS, RSCS, and IPCS) 229

In the followinq example, the responses (format, 131, device type, 000, end cylinder, and VMRELn) format the real disk at address 131 and
label it VMRELn. The label you specify must match what you specified in
the SYSVOL operand of the SYSRES macro statement when you defined the
system in your DMKSYS module. In any case, do not use CPRnLO because
that is the label of the starter system disk. The console output looks
like: VM/370 FORMAT/ALLOCATE PROGRAM RELEASE n

is displayed. Now that the system residence volume is formatted and
labeled, you must allocate the disk space. Again, you must respond to
the promptinq messages. In the following example, the space on the
various device types at address 131, with the label VMRELn, are
indicated. You can use the formulas given in the "Creating Your VM/370 Directory" section of Part 2 to ensure enough space is allocated for
your VH/370 directory. If you do not allocate your DASD space as shown
in this example, you are responsible for ensuring that you have enough TDSK space to perform the assemblies associated with VM/370 system
generation.
