Adaptec 2020SA sata raid controller doesn't see his RAID5 anymore. At boot the controllor says:
Configuration change has been detected in the system, if you reject the config change, you'll not be able to modify current configuration. If you accept, it will be updated to the current configuration.
If I accept the RAID5 is gone, but I can still see the disks. And they are in OPTIMAL state. If I reject he knows of the RAID5, but can't do anything.
If I boot with an extra disk to windows and install the ASM, it too sees that those disks are 'linked' and even sees the hotspare but he does't recognize it as a RAID5 anymore. If I select them and ask for status it says: Logical Device: Failed. (and still all disks are in OPTIMAL condition)...
Any advice how to get the raid back online?
