Bought a new Drobo FS yesterday to go with my FW800 Drobo 2.
Got the device home, slapped in a few disks (1x WD Green 2TB, 1x Seagate Barracuda LP 2TB, 2x WD Caviar 250GB) and started up the machine.
Response was 5 disturbing red lights on the face of the FS and an odd message from Drobo Dashboard: Unknown Disk Set Version. The system prompted me to check for new Dashboard software and device firmware, which I permitted, but no change in status.
Filed a support request with Data Robotics through their notoriously secretive process (unlike the public forums that every other tech company on the planet uses) and got a call from a tech support guy today. Although he professed to having no idea what the problem actually was, he proposed the following procedure to try to solve the issue:
1. Power down the FS using the back switch (hold in the off position for a few seconds); 2. Disconnect the power and ethernet cables from the back of the FS; 3a. Insert and hold a paper clip in the little reset hole; 3b. Reinsert the power lead; 3c. Power up the FS; 3d. Wait for all lights to turn green (note that "green" on the FS is a proper bright green while the "green" on a regular Drobo is more similar to "yellow" on the FS). Startup should take a minute or 2 and the little blue capacity lights will dance about a bit; 4. Remove the paperclip; 5. Power down the FS using the back switch (I actually forgot to do this part, but probably best to follow all instructions to be on the safe side); 6. Insert ethernet; 7. Power on.
