hi,

it does not look good. your disk may crash or about to.

do this:

# lvdisplay -v /dev/vgXX/lvolXX|grep -i stale
if any output is shown, that is bad news.

keep me updated.

regards.

[Mohammad Kaleem]

Thanks a lot, I would update you shortly.

The device causing the problem is b_dev: cb000000

0xCB=203dec

Just do a lsdev

I think it should point to sctl.
the device is 0x000000

I am not sure whether this points to a media changer.

SCSI resets can occur

1.When the SCSI termination is not OK.It can also happen when you reset your device or remove the cables.

2.check with proper SCSI patches for your OS

3.Also check whether the device is responding.

hi,

sorry for the false alarm. did not go through your syslog thoroughly. Manikandra is right, it should be the media device

# lsdev -C ctl
to check if the character is 203 which is cb000000 in hexdecimal.

regards.

DEAR,

This is a symptom of SCSI RESET. It may occur due to termination problem in any of your hard disks or scsi devices( external or Internal )
