Appendix C. Adding VM page space
This appendix explains how to dynamically add page space to z/VM without
system interruption. Note that the process is the same for adding spool space.
This appendix covers the following steps:
Verifying the current space allocation
Formatting a volume for CP
Allocating the page area
Adding the volume to the list of CP-owned DASD
Validating the CP-owned addition
Verifying that the page space was detected by CP
Making the dynamic change permanent in the SYSTEM CONFIG file
Optional:
– Adding new page volume to MAINT’s directory as a full pack minidisk
– Adding cylinder zero of the new page volume to the $ALLOC$ directory
– Adding the new page area to the $PAGE$ directory
