LP9802 with RHEL3 update4

[miaojian lin]

I have installed the LP9802 with RHEL3 update4 based on the document in emulex website. The SAN storage array present 3 luns to the box, and I see the 3 luns. But I always see error in my /var/log/message with "kernel: SCSI disk error: host 0 channel 0 id 2 lun 0 return code=4000) It didn't impact all the luns that I am seeing but it is arroying. In my /proc/scsi/scsi it shows
Attached devices:

the first 6 is correct because I have 3 luns with SPA and SPB. But I don't know why it also has the last one. Any help will be appreciated.

I've been looking at this thread on and off for days trying to figure out the issue. I also hoped one of the many people smarter than me would be of assistance. To no avail.

So don't look for a lot of helpful info from me.

It appears to me that one of your LUN's may not be set up correctly with its World Wide Name(WWN).

In genreal this is done by the SAN administrator. Perhaps that will get things started on this issue.
