How could the L2 machine bring them up if it does not have access to the
DASD that they require?
Your 2nd level machine should have very few R/W DASD linked, attached, or
dedicated.
Usually just the res/spool/page and very select DASD that it needs for its
own use (not shared R/W with L1).
We install Program Products on DASD labeled VMPP## (where "VM" DASD is L1
production).
The test system Program Product DASD is labeled VTPP##.
The 2nd level system may have some R/O links/Dedicates of VMPP## DASD, but
none of it is available R/W.
Those R/O Program Product DASD permit easy copying of MDISKs to the L2
system right from the L2 system ("CP DEFINE MDISK" is terrific for that).
The only DASD L2 has R/W is what it needs for its own use to IPL (not
shared R/W with L1), and its own DASD where its own userid MDISKs are
allocated.
You might find it valuable to suggest to your management that you really
should plan to attend SHARE in Anaheim this coming March.

IPL VM/VM Issues
L2 is a cloned L1 directory except for the volsers in the Directory and CF
Parm files which have all been made unique, ie 540 becoming 54X.
I plan to ipl as follows:
system reset
term conmode 3270
set mach esa
I 125b clear loadparm 009
START COLD DRAIN
To be safe, I suppose I should also add NOAUTO.
L1 runs 5 z/OS machines and 3 Linuxes.
They could be corrupted at L1 if I tried to bring them up in L2 at the
same time without GRS, MIM, or some other serialization product.
I doubt TCPIP will work at L2 without some reconfiguring.
So I should define some GRAFs and dial them.
Not sure if my L2 entry in the L1 Directory needs 54XRES, 54XPAG, 54XSPL,
54XW01, 54XW02 or whether I can just specify the IPL vplume, 54XRES, and
CP finds the rest from the Parm disk.
