cant mount external scsi drive
 
I have an AMI Megaraid SCSI card that I put in a RedHat 8.0 machine. On boot up redhat found the card and installed the driver. When i try to mount the system i get the following error:

mount: wrong fs type, bad option, bad superblock on /dev/sda1, or too many mounted file systems.

this is the command i used to try and mount the drive:

mount -t ext3 /dev/sda1 /mnt/external

in /proc/scsi/scsi i have the following:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun:00
Vendor: MegaRAID Model: LD 0 RAID5 210G Rev: G170
Type: Direct-Access

Can somebody help me with how to mount my drive? thanks alot

Are you sure you're mounting the right partition and with the right type? Do an fdisk -l /dev/sda1 to see what partitions are available on the device. Also, the dmesg output may provide useful information. Use dmesg | less to be able to scroll up and down (it's too big to fit in a terminal).

Does the SCSI card recognize the hard drive? (That is if the controller scans the bus at boot).

SCSI isn't hotplugable unless you have a chassis designed for it. If you plugged in the drive after bootup the controller will not detect the drive.

Is the SCSI bus terminiated correctly?

Has the drive been partitioned and formated? And does it contain an ext3 paritition?

Look at the output mesages of dmesg. Do you see any errors pertaining to the drive?
