How I can identify wich disk is dying?

Re: SCSI Error in Syslog

Berd — Mon, 19 Feb 2007 09:41:57 GMT

Run a ioscan against your disks to see if any are at fault. ioscan -fnC disk

Regards,
Berd

Re: SCSI Error in Syslog

James George_1 — Mon, 19 Feb 2007 09:42:31 GMT

To fine your disk :

# ll /dev/* | grep 0x160000

and also do
# ioscan -fnC disk | grep NO_HW
