Data Bay Indicators
Drobo utilizes status indicators found to the right of each Data Bay. These
indicators will always let you know the status of your Drobo. When all lights are
green "everything is okay." If there is a yellow light, you are running low on
protected capacity and you should add or replace a hard drive with one of greater
capacity at your convenience. A red indicator means you need to take action as
soon as possible, because you are critically low on space or not protected
against single drive failure. A blinking red indicator means that a hard drive has
failed.
Reference the following chart to best understand what your Drobo is telling you:
