today i experienced the following with my DroboPro.
After Mac start, the drobo showed a blinking PowerLED and all drive bay acitvations leds were off. The capacity leds showed up correctly and the drobo pro was accessible
by the mac. Even a restart of the mac could not solve this. I had to shutdown and restart the Drobo. In the documentation i could not found anything about a blinking power led. I am working with the newest firmware and the newest dashboard version over iScisi. Did anyone else experienced such behaviour?
My first step troubleshooting this would be to connect the DroboPro differently, maybe via USB instead of Firewire etc.
If the unit would still show that indication I would check if the unit also does that while it’s empty:
in other words - I would start the unit without any drive seated to check if Drobo Dashboard picks it up.
