CDL backup and copying the IPL record

[James Melin]

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?
