I'm using FW 2.00.09.1, but the problem is in FW 2.00.08 as well. When running the up_ps and ut_top tools from the UTILS modules it reports CPU on 2-5%. The led on the disks are flashing and from the sound of it the disks are working. The RAID is degraded at the moment, because of a faulty disk.
Anybody struggling with the same wrong reporting in the GUI?
