Once the Drobo fully boots up, it immediately goes into standby mode.
The Dashboard (3.5.2) never recognizes it and it never mounts to the desktop. It has the latest firmware too. The computers do not recognize it in system report or disk utility.
I’ve tried it on 2 Macs
an iMac running 10.15.7 (which the 5D3 was running fine until recently)
a Macbook Pro running 10.14
and both with the same result.
All lights are green (without any blinking) on the power supply & drives & drobo power button.
I tested the cables and they are good.
I have Gen3 which has no problems.
I’ve uninstalled dashboard and reinstalled it.
