Yeah, the amber LED on that first drive means it's failed. No lights on the 4th drive is weird... if it weren't assigned to an array or if it was a spare, that would make sense (or simply broken and the system didn't know it was there). But since it shows up in the drive list as being assigned to the ADG array, that's odd. Could just be a broken LED or the light tube isn't aligned, so you can't see the light. With the system powered off, you could remove that drive and take a look to see if anything is strange. Don't do it with the power on since you're in recovery mode!
The flashing of the other drives is just normal activity... the different flashing of one of them could just be based on how the ADG is recovering things at any given time.
Replacing the failed drive should get the array rebuilding, although the other message about the drive having an error during a previous rebuild is concerning... hopefully you have a backup of the data in case something got corrupted.
The 1716 error means that it encountered a problem on one of the drives during the recovery mode you're in now.
And you should update to the latest P410 firmware. 2.74 is ancient, as in 2010. 6.40 is the latest. I don't know for sure that anything specific in the newer firmware would make a difference, but it can't hurt. When you upgrade to that latest firmware, on the next boot it may tell you that one or more drives needs a firmware update. I have a pretty good feeling that if the P410 firmware is that old, the drives need updates too.
If that error is related to one of the drives having older firmware, the tech advisory says that it might not actually be a problem with the drive, which would be good news for you.

It says it only happens in zero memory mode (the controller doesn't have any cache installed). It looks like yours has 512MB so it might not be the case for you, but it's worth updating the drive firmware.
Best case, you replace the failed drive, get all the firmware updates in place, and the RAID 6 rebuilds itself and that 1716 error message goes away on it's own.
