Add the device to the option line for the dasd_mod in
the new device at the end of the list, otherwise it changes the
mapping and file systems are not on the devices they used to be on.
# vi /etc/modprobe.conf
# cat /etc/modprobe.conf
alias eth0 qeth
options dasd_mod dasd=201,4B2E
Rerun to pick up the changes to
mkinitrd
mountable after the next IPL:
Note that the example below has been modified slightly for readability and for printing purposes.
Each line that ends with "(elf64-s390)" should be treated as one line with no spaces, such as
/tmp/initrd.AR1182/lib/dasd_mod.ko(elf64-s390)
# cd /boot
# mv initrd-2.6.7-1.451.2.3.img initrd-2.6.7-1.451.2.3.img.old
# mkinitrd -v initrd-2.6.7-1.451.2.3.img 2.6.7-1.451.2.3
