SCSI trouble...

[OLIVA_1]

Hello,

On a D390 server with HPUX 10.20.
It seems I have a disk or a SCSI issue...

Just before rebooting I had this HW issue:

Someone can help me ? What is the issue ?
Now when I launch "dmesg" I have this message:
# dmesg

Jul 6 12:05
Can't get kernel namelist
#

???

Thanks,

"SCSI: Request Timeout" is caused by the kernel driver thinking that the request to the device did not complete.

Check the hardware connection/cabling. It could be more severe, and be a bad root disk as well.

The device is dev: 1f008000
# ll /dev/dsk |grep 008000

hi,

device 0x1f008000 refers to c0t8d0 and i think you have a failing disk.

check it with dd

dd if=/dev/rdsk/c0t8d0 of=null bs=1024

do it three to four times and check the values of records in and records out..both should match..

If you have STM bundle installed, do a non destructive check with cstm or mstm

with best wishes

The problem is c0t8d0.

Note that in the ioscan, it says "NO_HW". This means that you either have an old device file for a device that you meant to disconnect (and did) but its still in the kernel.

If this is the case then you need to use rmsf to get rid of the device file information.

OR it means that you have a broke disk drive at that location and need to open a HW call.

Best regards,
