Re: SCSI Reset Errors
In most cases you will find that this particular error relates to actual timeouts between your server and the disk array that is servicing. To fix this problem have a look at increasing the SCSI timeout for that LUN or even all of your LUN's in your disk array. The use of the 'pvchange -t' will look after this. There is a man page for this as well.
As an example I would look at increasing this value to 180.
pvchange -t 180 /dev/dsk/c2t0d2

Re: SCSI Reset Errors
Thanx for your help. I identified the disk and ran dd to find for errors. It got terminated with I/O error. Now I am planning to replace the disk.
Thanx & Regards,

Re: SCSI Reset Errors
IO error does not necessarily mean a faulty harddisk. It could be a faulty SCSI cable or terminator. It could be the SCSI card.
