These errors might mean you have a disk that is breaking down, or a flaky SCSI cable, or if you use an external disk cabinet, a problem in that cabinet, like a flaky power supply.

What you should do is check the syslog.log file for more messages like these ('grep "SCSI: Read" /var/adm/syslog/syslog.log') and if there are many, start checking your backups and looking for a new disk if the values between dev: and errno: are the same (they can be translated to the device: block device with major number 31 and minor number 0xa000, to translate that to the human readable form, go to /dev/dsk and do:
ls -l | grep '31.*a000')

Hi,

Error is coming from SCSI Subsystem.
go to /dev/dsk directory and find out device which has major number 31 and minor number 0xa000

problem is related to this disk.

the
0x00a000 Jun 10 1996 c0t10d0

and

0x03a000 Jun 10 1996 c3t10d0

which disk can have err?

[Sunil Sharma_1]

Hi,

I think it is c0t10d0

Hi,

Could you attach your syslog.log file.

Sunil

[Elmar P. Kolkman]

Please only attach it if it's not too large, otherwise attach the last days in the file...

Have you checked if the error is occurring just once or if it is a frequent error?
