I thought there was a question about HW vs. SW as the cause - as I  
understood it the HW was powered down fine, sat idle for 2 months,  
then you put Solaris 10 on and saw problems with SCSI controller and  
were uncertain about the nic.

Seeing Solaris 9 running fine on same hardware would confirm a  
software issue, the same symptoms as you are seeing under Solaris 10  
would confirm a hardware issue.
