raid 6 can't foreign & undetected disk fail

I have a PERC H710 Mini with RAID 6 virtual drive configuration that is offline. The virtual drive has a configuration of 8 disks, but there is 1 disk that is damaged and cannot be detected, and 2 disks have a foreign status. I cannot "import foreign" because the virtual drive is offline, and I cannot "replace member" the damaged disk.

Is there any advice for the situation described above?
