We successfully used the dedicate command to assign the entire z/OS volume
an LPAR to a device under VM.
So if you had A200, A201, A202 and A203 under LPAR you would dedicate
those volumes as the same device number under VM and then your Linux would
be able to IPL and see the devices where it expects to find them.
With VM, wherever possible we used the same device numbers for each guest.
For instance, 200 is always /dev/dasda1 and is a 1 gig swap volume. 201 is
always a mod 9 and is also the IPL volume, 8000,8001,8002 are always the
hipersocket interface. 9000,9001,9002 is always the GBE.
This makes it possible to have consistency across servers, regardless of
the fact that on guest 1, dev 201 is on VM volume abcdef and guest 2, dev
201 is on volume mnopqrs.

Our z/VM environment includes the vols we genned into our Linux LPAR. I am
assuming that after the VM install, we can create a guest and map the
minidisks to the vols currently used by the Linux LPAR and bring it up as
a guest. Will this work?
I presume that I would have to change some config files on the Linux
(/etc/chandev.conf and the like).
TIA
