Hello all,
I have a problem with an upgrade, from OpenSuSE 11.3 to 12.1. On the old version of the distro, the hard disk devices are listed as /dev/cciss/etc., into the new release are listed as /dev/sd[x]. The problem is the upgrade don't see the older partition (Install from DVD), and don't see any SuSE to Upgrade.
What can be the right manner to solve this situation, and upgrade to OpenSuSE 12.1 without re-installing all?
Cordially,
Claudio Prono.
I agree with Carl - I think you will have more problems going from 11.3 to
12.1. Strongly recommend 11.3 > 11.4 > 12.1.
Next, you are mixing apples with oranges about the disks. /dev/sdx is a
single physical disk, /dev/cciss is a raid device. I'm only guessing here but
I suspect the reason the DVD doesn't see the arrays is because the
installation kernel does not have the kernel module/driver it needs to see the
raid controller. Look at your 11.3 system with lsmod and modinfo for the
module; it's likely it is in the initrd and so defined in /etc/sysconfig/kernel
(which you can view with YaST /etc/sysconfig Editor).
If my guess is correct, the question becomes how to get the installation
kernel to load that module. Long ago I would use linuxrc to do that, either
by getting into its gui screen where you can specify modules or by using the
insmod argument. But I'm not sure that is even possible anymore.
