When I go to status -> hardware I see the following message:
Adaptec Unknown device 028b

Solution:

Unknown device means that pci ID label of device is not recognized by system, but driver is working properly.

 In order to resolve that problem please update you Adaptec Storage Manager to version 7.30.b.18837.
