Problem with 2nd HDD

muah · 01-12-2004, 10:41 AM

Hi,

i want to add an additional hard drive to my file server but i have a few problems I d like u to help me with

I installed the new hard drive into the computer (as secondary master) without problems, BIOS can see it, Red Hat 9.0 can see it during its boot as well.

But the problem is that when i want to use fdisk to remove existing partitions and create new i get following error:

Quote:

[root@Server /]# fdisk /dev/hdc

Unable to open /dev/hdc

1) Any ideas what the problem could be?

There are only two IDE devices in the PC, this one and hdd with RedHat (Primary Master)

2) Is there any command which could be used for displaying HDDs and their partitions Linux can see?

Thx in advance

Muah

...... this one and hdd with RedHat (Primary Master)

are you sure about this ...

naming is as follows :
hda = primary master
hdb = primary slave
hdc = secondary master
hdd = secondary slave

Thx

I m sure about the fact that hdd with linux is primary master and 2nd hdd i want to add is connected as secondary master, no other ide devices.

'dmesg|more', look for errors involving hdc. I saw a hd that was detected by bios, but not by an os. It was installed improperly.

Just throwing out some ideas.
Make sure the master/slave jumper is configured correctly.

Was there every a CDROM as hdc? Make sure there isn't a hdc=ide-scsi line the the grub or lilo config file.

muah · 01-12-2004, 12:46 PM

Yes, there was CD-ROM connected as secondary master when I installed the system a few months ago, then i removed it bc it wasnt necessary to have it there.

Content of my grub.conf:
---

default=0
timeout=2
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-8)
root (hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.20-8.img

---

Do u think that this could cause the problem?

muah · 01-12-2004, 01:00 PM

Oh yeah, it helped.
Thanks a lot to all of u.
