Does the EXTENT: specified relate to the order of the PARM on the SYSRES
disk? (i.e. 1 will always be the earliest PARM allocation on the disk)
CYLINDER ALLOCATION CURRENTLY IS AS FOLLOWS:
TYPE START ENDTOTAL
- ----
PERM 0
Yes it does. PARM 39 is CF1 PARM 159 is CF2 and PARM 279 is CF3, unless you
relocate the PARM allocations.
BTW, if you would press enter on the SAPL screen, it will show the CYL or
MDISK OFFSET of each PARM disk.

Yes - and you can have more than up to 9. Oddly enough - this is
documented in HELP CP SHUTDOWN -- see the EXTENT option...

Oh, if you change the extent and hit enter, it will show you the offset
of that PARM disk. And if you enter an undefined EXTENT:

The allocation map of the PARM disks and the MDISKS: CF1, CF2 and CF3 in the
MAINT VM directory must all match.
Pressing enter on the SAPL screen will replace the zeroes with the CYL in the
MINIDISK OFFSET.
You can also change the EXTENT to 1 2 or 3 ... whichever PARM disk you want to

Shutdown z/VM.
Reboot.
IF, repeat, IF I did it correctly and or there are no other
problems then fine.
BUT, if there are problems, I may need to return to the original
system config. THAT's where I want to make sure I understand this
right. I can at z/VM load time, change the parm disk from CF1
the starting cylinder, you can specify the extent
number of the parm disk on the IPL volume that you want to use. If you
are using the CF1, CF2, and CF3 disks that are built when you install
z/VM, CF1 is extent 1, CF2 is extent 2, and CF3 is extent 3 on the
installed IPL volume.
You can also have multiple

Booting of a different parm disk
Folks,
I've been informed that we're moving to new physical dasd probably next
week. So, I think this will work but was looking for verification
Backup current System config to from cf1 to cf2.
Change system config to new CUA's
Yes indeed, that's enough.
And, if CF1 and CF2 are allocated as PARM, no need to remember the cylinder
numbers, just say the n'th PARM disk in the EXTENT field
