Hello Mark,

I meant fast in a way that the / is copied and then changes the hostname and IP 
address. No other fancy things, just a default environment for our support 
staff to play around with.

The cloning process is loosly based on the cloning scripts from redp4322. The 
dasd is copied using DASDFMT and dd. Both source (installation machine) and 
targets are identical, other than the obvious different location of the 
minidisk extents. The / is a 3338 cylinder minidisk so there it even uses the 
same minidisk extents but on different DASD volumes. There is one thing I now 
see, I first regarded as an error due to new disks, but it is still present 
even when the disks were in use for the guest before. When the copy is done 
there are some IO errors.

The disk is linked, then DASDFMT and dd. It looks like the IO errors appear 
within the dd part of the copy process. But how to fix that? Should the guest 
have some mdisk option to avoid errors?

Thanks, Berry.
