Phil is right. The PATA drives are connected to the main board IDE channels.
There are two expansion cards in the PCI daughter board (riser): an Ethernet card and a two-channel IDE card. Channel 1 of the IDE expansion card is connected to the DVD drive.
Phil and I wanted to boot from the original DVD drive to inspect and possibly edit the Grub menu list. The BIOS was not reporting the original optical drive so we replaced it. The BIOS continues to report the FD and the two PATA HDs, both connected to the main board, but still does not report the optical drive.
Last night I reseated the PCI riser bus, the IDE expansion card and the data and power cables to the optical drive. The BIOS still wouldn't report it although the LED in the optical drive lights up during bootstrap. Oddly, the Linux kernel detects and reports the optical drive. But, because the BIOS doesn't "see" the optical drive, it is not in the Boot Order menu, and the BIOS won't boot from it.
My options seem to be: 1. Replace the IDE/optical drive data cable. 2. Move the IDE/optical drive to channel 2 on the PCI expansion card. 3. Replace the DVD optical drive with a simpler CDROM drive.4. Connect the optical drive to the slave data connector on one of the onboard PATA HD cables.
5. Replace the PCI IDE expansion card. Tom -- Mike Cook wrote:
It sounds like the raid card isn't being used for raid which would seem to indicate that either no raid is being used for the hard drives or that the server is running software raid and using the raid card for additional ide channel(s). I have seen. some ide raid cards (Promise) that use the onboard ide channels though. I would proceed carefully if we wish to salvage data. -----Original Message-----From: Imre <imreb321@xxxxxxxxx> Sent: Jan 5, 2012 12:06 PM To: frgeek-michiana@xxxxxxxxxxxxx Subject: [frgeek-michiana] Re: Server update gone bad Then it seems to me that's the problem. The motherboard bios is not seeing the optical drive, therefore it cannot boot from it. The optical is probably being recognized by the raid card bios only. But the system will not be able to boot from the optical. You have to connect the optical to the onboard ide.

The goal was to find, copy and edit the GRUB conf file. btw, the contents of the Grub conf file are displayed on the console for about 1-2 seconds, too fast for me to pause the console output. The server wouldn't boot off the optical drive even though we set it as the first boot device. The BIOS continued to boot off the hard drive. Phil and I disconnected and reconnected cables with no improvement. Assuming the BIOS doesn't see the optical drive or the drive is broken, we installed a DVD ROM from inventory. We must have disconnected the floppy drive because the server won't boot and throws the type of error you'd expect from a bad or disconnected FD. We ran out of time and will pick it up again tonight, starting with reconnecting the FD. Here is what I transcribed from the end of the console on booting. It appears the BIOS is not using UUID.

It makes sense to use it there when you have multiple drives because it guarantees that your mounts will all work even if boot order changes for some reason. Each file system is assigned a UUID upon creation. You can use the basic tools for that file system to find out what the UUID is. It will never change, even if you move the drive to a different server. It will also not change if you clone the partition. If you are able to boot from a cd, I think you can use tune2fs -l /dev/<hdxx> to see the UUID for the file system on a given partition (assuming it is ext2/3/4.) This page also lists some other ways (I haven't tried them) to get the UUID http://liquidat.wordpress.com/2007/10/15/short-tip-get-uuid-of-hard-disks/ The ls -l /dev/disk/by-uuid way looks pretty cool.

I've been very busy over the holiday and out of town for a few days. I ran 'apt-get update' using the default 'stable' sources, but that listed a lot of unverified packages which turned out to be Squeeze packages so I never started the upgrade. After some research I realized I needed to stay at Lenny by changing the sources from 'stable' to 'Lenny' as stable now means 'squeeze'. That seemed to work as the number of unverified packages were very few. I don't know UUID. I'll research it at the workshop tonight. afaik, there is no data backup. I'll try booting with a rescue disk and poke around. As a last resort, I will pull the drives and try to read them on another system. I don't know yet whether the drives are SCSI, SATA, PATA or some combination. I believe the drives were in some sort of RAID config.

When the server first tried to boot it died trying to load drivers for hdc or the next item after that; I couldn't tell which.

The source lists for apt-get were set to "stable" repositories. Since Debian advanced to v6.x 'Squeeze', stable was resulting in v6 packages which wouldn't verify. So I changed 'stable' to 'Lenny' (Debian v5.x) in the sources list, and the update/upgrade sequence went much better (until I rebooted). I'm not sure if there was a kernel update or not. The server is running RAID and possibly LVM. I seldom use either so I'm not well versed on either. Also, Debian uses Grub (possibly several versions of Grub). Grub runs on my Ubuntu 10.04 LTS netbook install, but I never touch it. Any ideas?
