aac support for Adaptec 2020SA ZCR

Mon Apr 11 00:30:49 PDT 2005

We have a motherboard (Supermicro X6DHT-G) with an Adaptec 2020SA SATA 
RAID controller. We have been unable to get any drives recognised by 
the FreeBSD 5.3 release installation CD, and we've been unable to find 
much discussion about the status of the AAC device and support for this 
chipset. Several other Adaptec SATA RAID controllers seem to be 
supported: 2410SA, 2810SA, 21610SA. The logical drive configured in the 
RAID controller is detected successfully in a Gentoo Linux 2004.3 
environment.

Has anyone had success with this controller? Any alternative you would 
recommend or will support be available in 5.4? I believe from the 
source code that the driver is maintained by Scott Long and that recent 
changes have been taking place.

Thanks for any assistance.
