Starter Systems Step 8. Set the Terminal Mode and Spool the Console If the system console you are is a display device, you should at
this point spool your console output so that you have a record of what
you do. To spool the console input and output, issue the command:
spool console start
to save a copy of the system generation.
Because the default terminal environment for the primary system
operator is CP, you should also issue the command:
terminal mode vm
The virtual machine terminal mode lets you remain in the CMS environment
when you enter data on the display device. Step 9. Define or Attach the System Residence
Device
The CPGEN virtual machine assumes that the system residence volume is
labeled VMRELn, and that it is a device type like that of the starter
system volume and resides at virtual address 350. Device types unlike
that of tbe starter system reside at virtual address 351, 352, and 353.
If you labeled your system residence volume VMRELn in Step 2, your
system residence device is already available; now you, as the operator
of CPGEN, must define it. Use Procedure 1 to define it.
To see which virtual device was defined as your system residence
volume, issue:
query virtual dasd If you are using a
volume, it will appear to Model 1 devices can ignore
be aware that this permits
residence. 3330 device for your new system residence CPGEN to have 808 cylinders. Users of 3330 this. Users of 3330 Model 11 devices should
them to use any part of the volume for system
If you did not label your system residence device VMRELn, you must
now attach it to your virtual machine, CPGEN. Use Procedure 2 to attach
your system residence device.
For example, if you used the values shown in Step 7, you designated
the 131 drive, labeled VMRELn, as your system residence device. You must your virtual device 350 so that it corresponds to the real
disk 131. Use one of the following procedures to define or attach your system
residence volume: • Procedure 1
If you are creating a system residence with label VMRELn, see the
following table to determine which virtual device must be defined as
131.

• Starter Systems Enter the following command:
define nnn as 131 Where nnn is 350, 351, 352, or 353. Starter System Residence Device Type System Device Type 2314 3330 3340 3350 2314 350 351 352 3.53 3330 351 350 352 353 33LJO 351 352 350 J...., 3350 351 352 353 350 Procedure 2
If you did not label your system residence volume as VMRELn, you must
attach the volume to your virtual machine now. Enter:
attach 131 to cpgen as 131
Note: The first device address you specify in the ATTACH command is
for the real device; the second device address is for the virtual
device. The real 131 is the system residence volume you formatted in Step 2. The virtual 131 is the system residence device you defined
in DftKSYS (using the SYSRES macro instruction). The system residence
device was also entered in response to the message:
ENTER DEVICE ADDRESS WHERE SYSTEM RESIDENCE WILL BE BUILT (CUU): Step 10. Make Other Devices Available You must attach your tape drives and designate the printer to receive
abnormal termination dumps if they occur. Use the explanation that
follows to decide how to do this. Press the Request key before entering
each command, for example:
attach 280 to cpgen as 181
attach 281 to cpgen as 182
set dump OOe In the first command, the real tape drive (280) attached must be the
same real address you entered in Step 7 in response to the message: ENTER ADDRESS WHERE STARTER SYSTEe TAPE IS (CUU): This real device must be attached to CPGEN as 181, because the VMSERV EXEC procedure (which is used later) expects it to be 181. Mount your
system PUT on this tape drive for Step 13. Part 3. Generating V"/370 (CP, CftS, RSCS, and IPCS) 239
