Question, what is the value of using diag for swapping to vdisk? Even if it is a more efficient driver, you're swapping to memory. How much does it save? And how much swapping would you need to be doing for any savings to be worthwhile? Wouldn't it be simpler to just increase the VM size to an amount that minimizes swapping? Or are there servers you *want* swapping a lot for some reason and if so why?

No, I would have expected it to be transparent. Email me your new initrd off list and I'll take a look at it. I'm suspecting that for whatever reason, dasd_diag_mod isn't being included in it. If that's the case, adding it to /etc/sysconfig/kernels will fix it, but I'd like to see the initrd.
