No such device or address

[Jonathan Caplette]

Hi all,

I got a little problem here, I have a magneto optical disk drive on an HP J5000 Vizualise workstation with HP-UX 10.20 and when I'm trying to mount the drive the system report thi to me:

/dev/dsk/c0t2d0: No such device or address

I looked to the /dev/dsk and /dev/rdsk directories and the device is in... I've powered off the drive and powered it on without success...

Can somebody help me... Thanx...

Hi,

check at first the corresponding device files and the SW/HW state with
ioscan -fn

Issue an "insf -e" and try again mounting the drive.

Regards,
Martin

Martin, I've tried the ioscan -fn command, but I can't see my device... have any clue?

Hello,

well if ioscan does not show the device than either it is blown up or disconnected from the system. You need to do a physical check first.
BTW if its not shown up in ioscan, where did you get the device file. Also check for id clash.

Goodluck

Jonathan,
I agree with Ajitkumar, looks a bit like a hardware or connection problem. You could use another set of SCSI cables and connectors and check for correct termination.
Does any other device show up in the ioscan output on the hardware path of the drive?
Another thing you can try is to assign the drive a different SCSI id. If any, you could connect the drive to another SCSI controller.
Check the device files of the drive with the lssf command.
Hope this helps,
Martin

Insert the driver in the kernel.

Thanx all... It seems that it's an hardware problem... so I'm gonna get it fixed...
