Topic: can't mount new hdd

[zipp]

I have setup in my server 6.01 a new harddrive.
On the second IDE = /dev/hdc.
It looks fine in BIOS but when I start the server and,
fdisk /dev/hdc then the reply is "Unable to open /dev/hdc" What can be wrong?

[BobWilliams]

How is the drive selected? Master or Cable select? It needs to be selected as either Master or slave not cable select. Does it show up in pico /etc/fstab?

In /var/log/messeges I can find something like

looks like hdc is busy?

I have tryed to all settings cables..
cable select, and master/slave both the same. BIOS detect is fine but not the server

[BobWilliams]

It looks like the drive you are trying to install has surface damage. I would if you can, attach it to a Windows PC and have Windows create a partition with fdisk, format it and fix the bad sectors if possible.

[BobWilliams]

This is a 160GB hard drive. Maybe thats the problem. I haven't tried to install that large a drive in SME 6.

Bob...

[zipp]

I have now 2 160 hardrive, /dev/hda and /dev/hdb
The drives are new I have also tried to setup in other pc with windows. And the drives works fine there. So still I can't use /dev/hdc but all others are fine.

[BobWilliams]

Could you try to see if one of the drives hda or hdb will work in the hdc position? Have you tried using a different cable for the IDE secondary drive? Is the BIOS setting for type of drive "MODE"(LBA,Large, Auto, Normal)set to Normal? Normal is preferred.

I could find this in, /boot/grub/grun.conf

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hda3
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title SME Server (2.4.20-18.7smp)
   root (hd0,0)
   kernel /vmlinuz-2.4.20-18.7smp ro root=/dev/hda3 hdc=ide-scsi
   initrd /initrd-2.4.20-18.7smp.img
title SME Server-up (2.4.20-18.7)
   root (hd0,0)
   kernel /vmlinuz-2.4.20-18.7 ro root=/dev/hda3 hdc=ide-scsi
   initrd /initrd-2.4.20-18.7.img

There it tells hdc=ide-scsi....
Can this be a problem?

[zipp]

I solved the problem.
This is my lilo.conf

linear
image=/boot/vmlinuz-2.4.20-18.7smp
   label=SMEServer-smp
   initrd=/boot/initrd-2.4.20-18.7smp.img
   read-only
   root=/dev/hda3
   append="hdc=ide-scsi"
image=/boot/vmlinuz-2.4.20-18.7
   label=SMEServer-up
   initrd=/boot/initrd-2.4.20-18.7.img
   read-only
   root=/dev/hda3
   append="hdc=ide-scsi"

I removed the last line: append="hdc=ide-scsi"

[BobWilliams]

Glad you got it working. I'm not sure you solved the actual problem as that same hdx=ide-scsi statement provides SCSI host adapter emulation for IDE ATAPI devices for the other drives on your server and they work OK. Have a look at this How-TO and see if it shed's any light on the actual problem.
