SYSRES Macro SYSVOt=serial is the volume identification of the system residence disk. The
volume serial number, serial, is a character string with a maximum
length of 6 characters. SYSRES=address designates the device address of the DASD to contain the
newly-generated system. This address is used only when the VM/370 nucleus is generated and written on the disk. Thereafter, you can IPt the system from any addressable disk device. The address is a
3-digit hexadecimal device address. 2314
2319 \3350} is the device type of the system residence device.
For a 3350 device in native mode, specify 3350 as the device type.
For a 3350 being used in 3330 compatibility mode, specify 3330. Specify a 3344 disk as a 3340, and a 3333 as a 3330. 2305 applies
to both 2305-1 and 2305-2. SYSNUC=strtcyl is the number of the real starting cylinder where the CP nucleus
resides.
The cylinder strtcyl is a 1-to 3-digit decimal number.
Normally, a 2314 or 2319 device requires five contiguous cylinders,
a 2305 or 3340 device also requires five contiguous cylinders, a 3330/3333 device requires three contiguous cylinders, and a 3350 device requires two cylinders, to contain the CP nucleus. Systems being generated with the virtual=real option require
additional space. For information about how much space to allocate
for virtual=real configurations: see "Specifying the Amount of Virtual=Real Space" in Part 1.

is the number of the real starting cylinder where the error records
are written, and optionally the number of cylinders required for
error recording. The strtcyl is a 1-to 3-digit decimal number designating the
starting cylinder of the error recording area.
The cylcount is a 1-digit decimal
designating the number of cylinders.

SYSRES Macro The strtcyl is a 1-to 3-digit decimal number designating the first
real cylinder where CP checkpoint start information is to be saved.
The cylcount value is a 1-digit decimal number (1 through 9) that
defines the maximum number of cylinders to contain checkpoint start
data. If cylcount is not specified, 1 is the default value.
The cylcount operand is optional; if included, the strtcyl and
cylcount operands must be separated by a comma and enclosed in
parentheses. Parentheses are optional when only the strtcyl
operand is specified.
The number of cylinders required for the checkpoint start data is
dependent upon the device type. They are as follows: 2305 2314 2319 3330 No. of Cl:linders 3 ,j ,j 4U 3350 r , SYSWRM=[ (]strtcyll , cylcount I [ ) ] I , 1 I L

is the number of the real starting cylinder, and optionally the
maximum number of cylinders, to contain the warm start data.
The strtcyl is a 1-to 3-digit decimal number designating the first
real cylinder where CP warm start information is to be saved.
The cylcount value is a 1-digit decimal number (1 through 9) that
defines the maX1mum number of cylinders to contain warm start data.
If cylcount is not specified, 1 is the default value.
The cylcount operand is optional; if included, the strtcyl and
cylcount operands must be separated by a comma and enclosed in
parentheses. Parentheses are optional when only the strtcyl
operand is specified. The following are valid entries for one
cylinder warm start areas: SYSWRM= (202, 1) SYSWRM= (202) SYSWRM=202 Use the following formulas to calculate the number of warm start
cylinders required. When you use the formulas, disregard all
remainders. For example, for a 3330 system residence volume plus: • A maximum of 40 spool files in the system at one time • A maximum of 170 cylinders available for spool files • A maximum of 50 active users at one time the calculation is
[59 + 40/40 + 170/170 + 200/50] 65
