You should now have newly formatted volumes that can be used for minidisks.
4.6.3 Updating the SYSTEM CONFIG file
Now that the PAGE and PERM volumes are ready for use, they must be added to the SYSTEM
CONFIG file so that z/VM can use them. Follow these steps to update the SYSTEM CONFIG file:
1. Log on to MAINT.
2. The following example uses the same steps to access the MAINT CF1 disk read-write that
you used earlier:
==> q cpdisk
Label Userid Vdev Mode Stat Vol-ID Rdev Type StartLoc EndLoc
MNTCF1 MAINT 0CF1 A R/O 610RES 61A2 CKD 39 158
MNTCF2 MAINT 0CF2 B R/O 610RES 61A2 CKD 159 278
MNTCF3 MAINT 0CF3 C R/O 610RES 61A2 CKD 279 398
==> cprel a
CPRELEASE request for disk A scheduled.
HCPZAC6730I CPRELEASE request for disk A completed.
==> link * cf1 cf1 mr
==> acc cf1 f
It is good to remember this sequence of steps.
3. Make a copy of the working SYSTEM CONFIG file using the “WRKS” (it works!) suffix
convention:
==> copy system config f = confwrks =
4. Edit the SYSTEM CONFIG file and specify each of the new page volumes (PAGE) by name as
CP_Owned. When your system performs an IPL, it will pick these up as paging volumes.
==> x system config f
====> /cp_owned
