i'm having trouble accessing some hard drives attached to a PCI IDE card.

the server is is used primarily as a backup machine, running Debian 3.0. there is a hard drive (hda) and cdrom (hdb) drive attached to the primary IDE channel on the motherboard. the secondary IDE channel is connected to 1 of the 5 swappable drives (hdc). IDE channel 1 & 2, on the PCI IDE card, connect to the remaining 4 swappable hard drives.

problem is, i can't find the 4 drives that are attached to the PCI IDE card. the drives that are attached to the mobo's IDE channels are 'hda' and 'hdc.'

dmesg output:

PIIX4: IDE controller on PCI bus 00 dev 39

$ e2fsck /dev/hdd
e2fsck 1.27 (8-Mar-2002)
e2fsck: No such device or address while trying to open /dev/hdd
Possibly non-existent or swap device?

# e2fsck /dev/hde
e2fsck 1.27 (8-Mar-2002)
e2fsck: No such device while trying to open /dev/hde

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

BENTBACKUP:/proc/ide# ls
drivers hda hdb hdc ide0 ide1

BENTBACKUP:/proc/ide# ls ide0
channel config hda hdb mate model

what are the drives named that are on the PCI IDE card? i assumed they would be hdd, hde, hdf, & hdg. guess not...

Make sure that you have compiled support for the card's IDE chipset into the kernel.

do:
lspci

to figure out what the card is, and a google search should turn up the appropriate driver.

Also, you should compile PIIX4 support in the IDE section of the kernel, so that you can get your mobo drives using UDMA.

thanks.

it is supported. now, how do i find the drives that are attached to this?

So... you compiled the Promise drivers into the kernel?
Sorry, not sure if you meant the kernel supports it, or you compiled yours to.

If you've got the proper modules/kernel support, then I'm at a loss. It should just.... work.
