Hi.
I've used ghost for change the ide disk for an array of scsi in raid using an adaptec controller 2110s.
Now when I boot it didn't boot correctly. Looking for in Internet (http://kbase.redhat.com/faq/FAQ_46_4969.shtm) I guest that I have to rebuild the initial ramdisk to contain the proper kernel modules for the adaptec controller. But what is the kernel module for 2110s in kernel 2.6.x? I also have to adding a line in /etc/modprobe.conf, but I don't know the format for that.
Thanks in advance.
Iago.

I don't know the details about that controller, but you should be able to boot the Centos install CD with linux rescue at the boot prompt and see what it loads. Follow the instructions to 'chroot /mnt/sysinstall' when it tells you to. Then if you missed the 'loading ...' during bootup you can probably find the module name with 'lsmod'. Add a line like: alias scsi_hostadapter aic7xxx to /etc/modprobe.conf but with the correct module for your adapter. Then run /sbin/mkinitrd with path and kernel version numbers to replace your existing on.

I'll try that. Thanks.

Newer Adaptec RAID controllers usually use either aacraid or i2o_block driver (the DPT I2O based controllers). If your's is using aacraid, you'll see the volumes as /dev/sd*. If it's using i2o_block, than you'll see the volumes under /dev/i2o/hd*. Try booting off installation CD into rescue mode and see what modules get loaded into the kernel.
Word of warning, i2o_block device driver seems to numerate drives in different order than BIOS, and depending how it is loaded it might numerate them differently (for example, I always get different order in rescue mode than when system is booted normally). In some cases, you'll need to instruct your boot loader what the BIOS thinks is the first drive (for example, I had trouble with LILO and this controller in the past because of that).
