Well after years of good service I unplugged Areca raid card and installed Adaptec RAID 71605Q.
Ouch! It's not recognized by DSS7.
In hardware setting is just " Adaptec Unknown device 028c (rev 01) ".
According this webcast http://vimeo.com/37887260 I assumed it could be working.
Unsupported or bios misconfiguration ? Ideas ?
Help appreciated.
