Just setup my first server. Using Adaptec ASR-7805 and can’t get it into HBA mode. When I change the controller to HBA in the bios I get and error that states mode switch failed, please delete all arrays and uninitialize disks and try again.
I haven’t set up an array or initialized anything. I just put everything together for the first time and trying to switch to HBA mode.
Unraid and the adaptec bios are detecting the drives fine.
You may not have configured a RAID array on the card, but the last guy did. It won’t be usable as an HBA as long as it thinks there is a problem with the thing it’s supposed to manage.
Not sure what happened between last night and today but it switched over fine.
I started a format in the Adaptec bios last night because I thought there may have been data in the refurbished drive. I cancelled it today cause it was over 24 hours and wasn’t complete. Went into controller settings to make the switch from raid to HBA so I can snap a photo of the error and voila, switched right over. The drives have the correct serial numbers in unRaid now.
