Symptom:

Power light is yellow. All other lights are off. 

Drobo automatically goes into Standby if your computer is in sleep mode or if your computer is powered off. 

Other reasons for your Drobo going into sleep mode include

  • The cable connection from your computer to Drobo has become lose or dislodged 
  • The cable you are using is no longer working
  • If using hub/adapter between Drobo and your computer, remove the hub/adapter and directly connect to the computer
  • The data port on your computer is bad. Try an alternative connection type (USB, Thunderbolt)
  • If your Drobo has an ISCSI connection and you are using a Mac, you will need the ATTO ISCSI initiator.

To resolve, try the following

  • Check the cable connection from your Drobo to your computer. Disconnect and then reconnect the data cable.
  • If on Mac, uncheck Power Nap in System Preferences, Energy Saver, Power Nap 
  • Try another port on the computer, another cable, and if possible another port on the Drobo storage device.
  • If in daisy chain configuration, remove Drobo from daisy chain and directly connect Drobo to computer.
  • Try another port on the computer, another cable, and if possible another port on the Drobo storage device. Especially if using an adapter or Drobo is in a daisy chain configuration. 
NOTE:

The fan will continue to spin on all DAS products while the Drobo is in Standby, this is to keep the drives cool. 

The Drobo NAS products do not go into Standby since they are connected to the internet and kept awake.
