Saved Systems Saved Systems Saved systems are described in detail in the VftLJ70 2Y§tem Programmer's If you plan to save core-image copies of virtual machine
operating systems you should do the following when you generate Vft/370. • Create an entry in the system name table for each system you wish to
save. • Reserve space on a CP-owned volume for each system you wish to save. You create entries in the system name table by coding NAftESYS and NAMENCP macros and assembling the system name table (DMKSNT) file during
system generation. You specify which volumes are to be owned by CP by
coding the SYSOWN macro and assembling the CP system control (DMKSYS) file during system generation. These macros and files are described in Part 2.
If you decide to add entries to the system name table after you have
installed Vft/370, you must code the appropriate NAMESYS or NAMENCP macros, reassemble the system name table module (DftKSNT), and reload the CP nucleus. Likewise, if you must add a CP-owned volume after system
generation, you must recode the SYSOWN macro, reassemble the CP system
control module (DMKSYS), and reload the CP nucleus. Use the GENERATE EXEC procedure to reassemble DMKSNT and/or DftKSYS and to reload the CP nucleus. GENERATE is described in "Part 5. Updating VM/370." Part 1. Planning for System Generation 79
