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 upsize a hard drive with one of greater capacity at your convenience. A red indicator
means you need to take action as soon as possible, you are critically low on space or not protected against a 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:

What It Means
Healthy system.
Drobo is getting full.
Protected space is critically low, or data
protection against a single drive failure is
no longer possible.
Do not remove drives. Drobo is
protecting your data by duplicating and
spreading it across all of the available
hard drives.
A hard drive has failed.
Drobo is starting up, there have been too
many hard drives removed, or too many
hard drives have been replaced at the
same time.
Action to Take
None
Add a hard drive or upsize the
existing one with a larger capacity
hard drive.
Add a hard drive or upsize the
existing one with a larger capacity
hard drive ASAP.
Don't remove any hard drives or
power down Drobo.
Warning: Removing a hard drive
while green and yellow lights are
blinking may cause data loss.
Tip: You can continue to access
your data while Drobo is protecting
your data. Just don't remove a hard
drive!
Replace this hard drive ASAP.
Wait a minute to make sure Drobo
is done rebooting. If the indicators
don't change to green, then you
may have removed or replaced too
many hard drives from your Drobo
at the same time. Identify the hard
drives removed and re-insert them
into Drobo. If you need further
assistance, refer to the User's
Guide.
Tip: When removing or replacing
hard drives, make sure you remove
or replace them one at a time.
Never remove a drive when the
data bay indicators are blinking
green and yellow.
