Note that adding kernel/module parameter dasd=autodetect should achieve
the same result.
That's really weird. We always specify dasd=autodetect. I even just
double checked to make sure. All of the disks are certainly detected,
they just don't come up online.
But, you've got me curious, so I'm going to modify an initrd and see if
the devices are online prior to any initrd processing. Mayhap something
in boot is putting them offline before udev is getting his mitts on 'em.
Probably not, but I just HAVE to know. :-)
Definitely detected but offline no matter if I specify dasd=autodetect
or a device range like dasd=0.0.0000-0.0.ffff. Even tried
dasd=0.0.0000-0.0.ffff,autodetect for the heck of it.
I just added:
grep -ir '.*' /sys/bus/ccw/devices/*/online
as the second line of the "init" script in the initrd. The only device
at this point that shows as being online is the console device (0009).
