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.

ENTER FORMAT OR ALLOCATE: Step 3. Label the Starter System Volume Use the Format/Allocate program to label the scratch volume that is to
contain the CP starter system. This label must be CPRnLO. You can
format and label this volume, or just label it. Formatting is
unnecessary (unless the pack has never been initialized before) because
you are going to restore the starter system to this volume. If you get
an I/O error trying to label the pack, format only cylinder zero and
then try to label the pack again. In the following example, the
responses (format, 130, device type, label, and CPRnLO) to the prompting
messages put the label CPRnLO on the real disk at address 130. ENTER FORMAT OR ALLOCATE: format FORMAT FUNCTION SELECTED

ENTER DEVICE LABEL: CPRnLO LABEL IS NOW CPRnLO - When the Format/Allocate program is complete, it responds:
ENTER FORMAT OR ALLOCATE: You need not respond to this message. Press the PAl key twice to return
to CP mode.
Now the starter system volume is available and ready for the data
that is to be placed on it by the DASD Dump Restore service program
(module DMKDDR). The DASD Dump Restore program is the second file on the
starter system tape. Step 4. Load the DASD Dump Restore Program from
the Starter System Tape IPL the starter system tape a second time to load the DASD Dump Restore
(DDR) program. It is the second file on the starter system tape. Do
not rewind the tape, because the next file is needed in Step 5. Step 5. Restore the Starter System to Disk
Respond to the DDR prompting messages to restore the starter system.
