Rajeev,

the line May 5 05:54:32 germany vmunix: bp->b_dev: 1f04c000

from your syslog output will point you to the problem device. its a disk.

ll /dev/dsk | grep 1f04c000

May 5 05:54:32 germany vmunix: lsp->state: 5
most of the time state 5 refers to device offline.

please chck the diskinfo, dd etc to check if the disk is OK.

Good Luck.

Ajit

Hi,

Try

ioscan -fCdisk ( if you find a disk UNCLIMBED) better raise a call with HP to get it replaced

I guess one of the SCSI disk is down or a cable not connected properly.

Hi Rajeev,

That device maps to c4t12d0
But it could be a transient condition.
Make sure it doesn't resolve as UNCLAIMED on an ioscan.

Rgds,
