Drobo 5N with All 5 red solid lights

I had the Drobo working fine until last night. I have four WD Red NAS Hard Drives filling bays one through four. Then all of a sudden all five drive lights went red. I tried resetting things but it after the Drobo tries to reinitialize it just goes back to all red. Can you tell me how to fix this? Thanks.

Do you know that resetting or pin-hole reset on a Drobo with Drives will wipe-out and formatted all the drives and all existing data will be formatted and lost???!

When you first encountered the problem with all drives RED… does the Dashboard detects the Drobo unit?? Did the Dashboard prompted any error message such as “Too many Drives removed… etc…”??
