I finally had a chance to do some digging and this is
what I came up with for taroon BETA (RHEL3) to
add/change device addresses and also to
make it ipl in an LPAR (the dasd_eckd_mod is missing -
I have an open problem on this with redhat and I don't
know how this will play out in the released
version.)
1) you specify the dasd devices in /etc/modules.conf,
i.e.
alias qeth0 qeth
options dasd_mod dasd=xxxx,yyyy,zzzz
2) Then you need to run mkinitrd:
a) do an "ls" on /lib/modules. The subdirectory name
is what you need for the mkinitrd.
For example, /lib/modules/this-release
b) mkinitrd --preload dasd_eckd_mod new-initrd \
this-release
3) change /etc/zipl so that
...
ramdisk=/boot/new-initrd
parameters="root=/dev/dasda1"
(also, other parameters, such as cio_ignore have
to be coded here)
4) do a zipl
