What I didn't realize is that the hostid is apparently written right on the chip
itself! I just received a couple of emails from folks telling me that. Thanks!
That's exactly what I need to make sure the system is using the correct one.

>>The machine is a 4500, with 2 system boards, 3 i/o boards, Solaris 2.6. Two

>>We recovered our nvram settings by copying them from one of the i/o boards,
>which from what I'm
>>seeing in testing today should have brought the original hostid back onto the
>clock board. But
>>when we booted the problem system after replacing the clock board, we had a
new
>hostid and have
>>been living with that ever since. After last night's shutdown however, I find
>we are back to
>>using the original hostid! What am I missing here? I don't really care what
>the hostid is, as
>>long as it doesn't keep switching on us because of license software.
>>
>>I spoke with Sun this morning and they are stumped. Any insight into how or
>where hostid
>>information is stored would be greatly appreciated.

>>TIA
