Peter, Try IPLing without the paging device and see what happens. If it still hangs at the first DASD device detection, then try running a CP instruction trace. You can compare the addresses to what in the /boot/System.map file to get an idea of what kernel routines are running.

I cannot find anything to suggest why they are not working. I can boot my install system, mount the disks and look around, but all the boots from October 3 on do not appear to be writing any log files. Following is the VM console log for one of the Linux guests. I would appreciate any help you can give. *********************************************** * Welcome to user LINUX03 at TTCVM01 * *********************************************** ************************************** * * * Today is Sunday, 30 Oct 2005. * * The Julian format date is 05303. * * The current time is 01:43:17. * * * ************************************** HCPDTV040E Device 0201 does not exist DASD 0201 DEFINED DMSACP112S L(201) device error DMSFOR603R FORMAT will erase all files on disk L(201).
