reset disk status flag from failed to OK or Pred. failure

Just bad luck ... 2 failing disks in one raid5 array. The system reported 2 failed disks during a reboot. After a power cycle and "F2" we were able to get the array back online and the system started to rebuild 1 disk. I don't know how it selected that one, but during the rebuilding the second bad disk gave a ton of read errors and rebuilding stopped... 2 disk marked failed.

Is there a way to reset that failure flag on the disk and trigger the rebuilding of the 1st disk? Accepting some read errors/failures.

I know it's an older box and it will be replaced, but I just like to know if I can reset/force that.

And when can I use this command ... seems just not to work as expected
