We have recently installed CentOS Linux on our test Linux LPAR. We would like to migrate it to our production LPAR without having to do a new install. CentOS is intalled on a single dasd volume. We would like to simply copy the volume and IPL to the new volume on the new LPAR. The problem is that after we IPL on the new volume, Linux is still pointing to the file system on the old volume. This is the process that we followed to try to change the dasd volume that Linux uses.
- change /etc/modprode.conf o changed "options dasd_mod dasd=322B" to "options dasd_mod dasd=322C" - run mkinitrd to pick up the changes to modprobe.conf o mkinitrd -v initrd-2.6.9-42.0.2.EL.img 2.6.9-42.0.2.EL o this showed the line "Loading module dasd_mod with options dasd=322C" so it seemed like changes were picked up. - run zipl command o zipl -V o contents of zipl.conf looks like this: * [defaultboot] * default=linux * target=/boot/ * [linux] * image=/boot/vmlinuz-2.6.9-42.0.2.EL * ramdisk=/boot/initrd-2.6.9-42.0.2.EL.img * parameters="root=/dev/VolGroup00/LogVol00" Output from zipl contained the following messages: DASD device number..............: 322b Preparing boot device: dasda (322b). Those messages lead me to believe that it is still pointing to the old dasd address. The plan was to make the dasd address changes, copy the volume, and then set the dasd address back to the original address on the old system, and IPL the new volume in the new LPAR. Is there something that I am missing? Is there and easier way to clone a linux system in a different LPAR? I appreciate any suggestions.
