Help needed with error message on K220 / HP-UX 11.00

[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. :)

It is fine here, are you getting any errors where trying to access the DLT.

Please post an ioscan -Fnc.

Hi,
if you think that the problem is the tape try it:

ll /dev/rmt |grep 0x48000

for the special file.

Hi

The first two hex digits (48) refer is the major device number. 48 = 72 (dec).

Do as lsdev and look for the matching driver.

Hi,

tape 2 10/4/8.0.0 tape2 CLAIMED DEVICE HP 7980S
/dev/diag/rmt/c2t0d0 /dev/rmt/2mb /dev/rmt/2mnb /dev/rmt/c2t0d0BESTb /dev/rmt/c2t0d0BESTnb
/dev/rmt/2m /dev/rmt/2mn /dev/rmt/c2t0d0BEST /dev/rmt/c2t0d0BESTn

If ??'m not mistaken, the above is the adres for the tape unit.

What kind of software are you using (Legato??)

Check from the command line

# mt -f /dev/rmt/2mnb status

# tapeinfo -f /dev/rmt/2mnb

Try writing something to the tape with tar/cpio

# cd /tmp
# tar cvf /dev/rmt/2mnb .

Hope it helps,

Robert-Jan.

Thanks for all the help folks.

Finally traced the fault to a disk in one of the HASS Arrays at H/W path 10/8.8.0

Reported it to our H/W vendor and the disk has now been replaced and the errors have stopped.

Once again, thanks. This was my first post on these Forums and I am mighty impressed with all the helpful suggestions.

Hope you all have a hassle free day.

Cheers,
Steve
