linux doesn't see my other 2 hard disks

tr6boy · 07-19-2004, 02:13 PM

I have a system running SuSE 9.1, which has 3 18 GB drives on an Adaptec scsi adapter.

I've been trying to figure out if the system recognizes the other 2 drives, and I don't think it does.

I found this command in researching the topic:

# ls /proc/ide

This returns the following:

drivers hda ide0 svwks

From this, I think only a single drive (hda) has been recognized. If that's correct, what should I do to be able to access the other two?

Thanks

If there are no partitions on the other disks Linux will not see anything.
Use an ap like QtParted to create partitions and then you'll be able to mount and see them

Hi Mr.,
the sub-directory /proc/ide, as the name implies is for ide disks. You have scsi disks. Try /proc/scsi.

that returns:

aic7xxx device_info scsi

That's just my adapter, not the disks that the adapter manages, right?

Sorry...still confused.

The /proc file system is a virtual fs. All you see on it are informations your kernel shows to you.. In the directory /proc/scsi you will see a directory which is your controller and one file named scsi with length "0¨. Enter

Code:

cat /proc/scsi/scsi

to see the configuration your kernel found.

You can try running cdrecord with the scanbus option. For example,
cdrecord -scanbus

If you do not have cdrecord, you can install the sg utilities.

As su or root, type fdisk -l /dev/sd[a-z]

With SCSI devices, you have to worry about adding terminating resistors to the end of the device chain. If you do not, you will get problems like a strange capacity on the end drive or devices after the terminating resistor will not be recognized.

I have not worked with SCSI devices but read a lot of problems and fixes about them.
