K220 error message, Need help with identifying hardware address

[Stephen Cowie]

I keep getting the following error on my K220 and I suspect it may be with an external DLT4000s but the device address in the error doesn't seem to conform to the normal format for working out a device path. eg (0x041000 would relate to device path C4T1D0) Could someone have a look at the error and possibly explain how to convert it correctly.

SCSI: Write error -- dev: b 31 0x48000, errno: 5, resid: 8192,blkno: 386376, sectno: 772752, offset: 395649024, bcount: 8192.
Retry count exceeded!

As you can see the address is 0x48000 so i'm not sure how this converts to a CxTxDx device name? Any help gratefully recieved. :)

c4t8d0
Check SCSI bus cables and termination. Also remember then SCSI Id8 has the lowest priority

Hi,
to decode:
b 31 -> block device 31 -> lsdev | grep 31 -> disk driver.
0x48000 -> 0xXYZ00 -> cXtYdZ
In your case it is the disk on c4t8d0.
You must check the scsi path, but in your case I bet for an media error, check by doing:
dd if=/dev/rdsk/c4t8d0 of=/dev/null bs=1024k
You will probably have an IO error -> I hope you have a good backup.

Cheers.

Thanks for that guys, It was the fact that there wasn't a "0" in front of the "4" that was confusing me.
