This is what I would like to do: boot from a mirrored DASD as part of a "catastrophe scenario" when DASDs fail or crash or whatever. I have no idea how to accomplish this. zLinux does take the mirror-load-adress, but as the log messages and lsdasd show, it uses the original DASD and not the mirrored one.
Look at options for the boot menu. You could create 2 entries in your boot menu, one where dasd= lists your primaries and one where it has your alternate addresses. All reference inside Linux are to the symbolic names. That mapping is established by the dasd= kernel option. I believe the ramdisk startup in SuSE properly picks up that option from the zipl.conf. If it does not, then you'll have to create an extra initrd and go through that way. I trust z/OS will already have broken your mirror before you try to IPL the Linux LPAR.
