Oy.
Well then, how would you recommend this be done? I have no decent facility
at disaster recovery to IPL a recovery CD and mount the disk images to
that. The vendor is reluctant to load anything from CD at the HMC. I'm
basically trying to take the file system images on the CDL volumes and back
them up using OS/390 tools and then restore them with the same tools, to
diff volumes, map those volumes to the same device addresses as they were
on the original system in VM and IPL.

Jim,
I don't think those two statements are either necessarily correct, or
incorrect. I would say that the "trick" is that the first cylinder to be
dumped to tape (and restored to disk at real cylinder 0) needs to be what
the Linux/390 system thinks is cylinder 0. That's where the IPL record
information is going to be. So, depending on how the minidisk is set up
(if
using z/VM), and how you dump it, etc., etc., etc.

Subject: CDL backup and copying the IPL record
If I understand things correctly, a DD dump of a linux volume will not copy
the IPL record, whereas a disk copy of the CDL image on the OS/390 side,
will? Is that a true statement?
Would this allow you to restore say a slightly pregnant mod-9 device (our
dasd person gave me an approximately correct size mod-9 and our disaster
recovery vendor uses real mod-9 geometry 1014 tracks too small) to a mod
27, and be able to read an IPL record off that device?
