Figure 30. Allocation of the Starter System Volume (CPRnLO) When the 3350 Starter System Directory Is Used Step 20. Back Up the Newly Generated VM/370
At this time, back up your new system residence volume. If your real
machine has at least 448K bytes of real storage, the tape created in Step 1A is sufficient backup. However, that tape is not sufficient
backup for real systems with less than 448K of real storage because that
tape cannot be loaded on such systems. It may also be inadequate if you
have a large V=R area. V!!/370 systems that run on a real machine with less than 448K bytes
of storage should use the DASD Dump Restore (DDm service program
to create a backup tape similar to the one created in step 18. The DASD Dump Restore program is described in the !M/310 If
your system residence volume is at address 131 and you labeled it V!!RELn, you could use the following DDR control statements to back it
up:
input 131 device type V!!RELn output 181 device type (tape drive)
dump cpvol
The DUMP CPVOL statement causes cylinder 0 and those disk cylinders
allocated as PERM or DRCT in Step 2 to be dumped onto the tape.
