Hi,
I am using FreeBSD-4.10 with isp driver on HP EVA-8k SAN box.
The description of the problem is as follows:
1. Two machines are using HP EVA-8k with only single controller active.
2. Both of these machines are doing heavy IO on the their individual LUNs.
3. Now if any one of the machine is rebooted, the other machine's OS
panics
and reboots. Both the machines are using FreeBSD-4.10.
Here is the debug info attached.

I am confused at why these "inquiry changed" messages are getting logged.
This seems to work with SAN boxes other than HP EVA-8k and EVA-6k.
Any ideas on why these "inquiry changed" messages are getting created and
are they cause of this kernel panic?
Thanks,
Rajesh
