I have a CKD file, created with the Hercules dasdinit program.
It's a (hercules) 3350 uncompressed file.
I've put a small "hello world" IPL program on it, and it works fine with
Hercules
When I try to run it with qemu-system-s390x I get :
LOADPARM=[ ]
Using virtio-blk.
Using guessed DASD geometry.
Using ECKD scheme (block size 4096), CDL
No zIPL section in IPL2 record. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
zIPL load failed.
Could not find a suitable boot device (none specified)
Failed to load OS from hard disk
The qemu script is :
qemu-system-s390x -m 16 -drive format=raw,file=test-ipl.3350.un,if=virtio
-nographic
I found this link re: the zipl command.
https://www.ibm.com/docs/en/linux-on-systems?topic=u-modes-syntax-overview
Where is that command and / or its source ?
Mike
