Add. hard disk drive on hdc did not work

Hi there!

I've upgraded my e-smith server from 5.5 to 6.0 beta3, which caused me some puzzles, I would like to share - and hopefully someone can tell me, where I failed... I'm still fairly new to this, so please bear with me... I have a sneaking suspicion that I just made a beginner's mistake...

My setup is 3 HDDs - one for the OS, and two additional HDDs for i-bays. I initially set them up as hda for e-smith, and hdc/hdd for i-bays. Well, actually first I only physically connected the hda to the motherboard and installed e-smith, and after successful installation, I connected the two other hard disks, to be exact.
I didn't have any problems with mounting the hdd (i.e. the slave on the sec. ide-controller), but the hdc could not be mounted (and I did check the jumper settings more than once). I tried to run a fdisk /dev/hdc (and fdisk /dev/hdcx for that matter), but I kept receiving Unable to open /dev/hdc. The hdd appeared correctly in the bios setting, and it also appeared when I executed ls /proc/ide.
Then I found some directions pointing me to look at the grub.conf. Here I found hdc=ide-scsi, which I guessed was wrong, and I first tried to delete it and secondly to replace it with hdc=ide-disk, but this didn't help me either. Going through a lot of different Linux posts on the Internet, I sort of reasoned that maybe it didn't accept a hard disk drive on the hdc, but only a CD-ROM or another IDE-controller, so I changed the hard disk drive to appear as slave on the primary IDE by changing jumper settings and cable connections to the MoBo - and then it worked with no problems...

So, I guess my question is: What did I do wrong, since I could not mount (/access) the hard disk drive, when it was installed as the Master on the secondary IDE (hdc)? Or is it really true that you cannot use hdc for a hard disk drive?

Thanks for any input...

Regards,
Klaus

grub.conf  is not used. You would need to change /etc/lilo.conf, and then run the command "/sbin/lilo -v". Just remove "hdc=ide-scsi".
