Problem with DD and mounting drives


Basically I'm trying to mount two IBM 6605 68 pin scsi drives. They are detected and I can find them in dmesg. The problem is that I can't mount them (funny naming scheme), and I can't run DD on them to at least get a copy of the data. Is there any way to look through to find out what is going wrong. I have looked for kern.log and that file is not present in /var/log. Is there anywhere else I should check, the dd has been stuck at 0+0 records since I started. I just checked for the first time it is 26000 seconds elapsed using the kill -SRC1 (pid) method. Any suggestions, these are from an AS400 running SSP (system support program) version 7.1, and when I try to mount them it says they are not a block drive. I've been googling to no avail, mainly because this is a very obscure problem. Any suggestions would be great. I'm not new to linux but I'm not an expert by any means.

Do you mean that the SCSI disks originated from an AS400 and you're now trying to use them on a Linux system?
If so, I'd reckon that you need to format the disks first. I'm not used to AS400s but I had to reformat disks reclaimed from IBM RS6000 systems before I could use them with Linux. Which Linux Distribution are you runing?

Not exactly

I'm trying to mount the drives, and pull information off of them. There was a system crash and I am attempting a recovery now, but so far I have had no luck. I am trying to do a DD but it gets stuck at 0+0 records in. I was under the impression that I did not have to mount the drive in order to pull information off. I'm going to try some new tactics to see if maybe the first few sectors can't be read. Outside of that I'm out of ideas, if anyone has any suggestions that would be great.

Try looking at /var/log/messages. If there are devices for them, there should be a log message when they were detected.
Could you post how the devices are named in /dev/? Also use "file -s <dev>" to get information on those devices.

Were the drives part of a raid 1 array?

You didn't answer my question. Do the drives come from an AS400? If so, was it the AS400 which crashed? Connecting AS400 formatted drives to a Linux system and hoping to read them may be a bit optimistic. Again, What Linux distribution are you running?

Guess is a termination issue. Go to scsi firmware and see if you can run diags on the drives and make sure they are in correct numbers.

dd works on almost everything that can work.
