Re: dmesg

A. Clay Stephenson — Fri, 24 Feb 2006 11:31:18 GMT

dev: cd023000

This decodes to /dev/rmt/c2t3d0BEST. The major and minor device numbers will also match the shorter versions of the tape device nodes. In any event, you have a problem with the tape drive. Try cleaning the drive and using another tape. Check cabling and termination. If that fails then you have a failing drive.

Hi,

I agree w/Clay.
This is a tape drive problem.
Could be as simple as a bad tape or the drive needs to be cleaned.
So clean it & try another tape.
If it persists you probably have a bad drive.

Jeff

Oh _ I forgot to add that it could also be that the write-protect tab is set on the tape.
Do a
mt status
with the tape in to verify.

Rgds,
Jeff

How is the tape device being accessed? Are you using the raw, no-rewind Berkley style tape device file e.g. /dev/rmt/0mnb.

Most likely cause of such an error is when the above convention for the device file is not used for manipulating the tape.

cheers!

Re: dmesg

Kent Ostby — Fri, 24 Feb 2006 14:35:43 GMT

ll /dev/rmt/* | grep 023000

will give you the device file for the device in question.

lssf /dev/rmt/[whatever] will give you the path code.

hi,

also use STM to query your hardware.

what is the output of the following command giving?:
ioscan -fknC tape

kind regards

Hi,
This seems to be a problem with the tape drive. May be the problem can be solved by using a cleaning cartridge. What's the LED(Color) indications on the drive, I mean clean.

Whatâ s the status of the drive in ioscan -fnC tape, is it showing â CLAIMEDâ

If clean LED indication is orange, use a good cleaning cartridge to clean the drive. Still the clean LED indication doesn't go off, replace the drive. Never attempt to open the drive and clean manually..

How about connectivity, check the connectivity and scsi terminations etc

Regards,
Sunil
