Suddenly things went wrong. After an Apple OS update to 10.11.6 on my iMac, my Drobo Gen 2 showed a full disk failure: 4 vertical red lights on the right side of the box, blue lights all along the bottom, and a non-blinking red power light. It stays like that for a while, then reboots, and the process starts over again.
All 4 of the installed hard disks are brand new w/in the last 4 months.
This is going to be a long description of what has happened since, but please understand that I bought this Drobo used, therefore have no warranty support from Drobo (which is fine, I understand that), but I need to get this Drobo back up and working again.
Drobo Dashboard did not recognize a mounted Drobo unit.
First step: I panicked a bit and thought that perhaps a software upgrade was needed, so I installed Drobo Dashboard 2.8.3. [color=#FF0000]That was a mistake: Drobo Dashboard 2.8.3 seems to be incompatible with Apple OS 10.11.6. At least is prevented my iMac startup from happening,[/color] so I uninstalled 2.8.3 and reinstalled v2.6.4, which seems to be working fine.
I cannot upgrade the Drobo firmware, because I can’t get Drobo to mount w/in Dashboard. But am not sure that would fix the problem anyway. I believe that I am running firmware v1.4.2 for Mac.
Current state: when I power up my Drobo Gen 2, it recycles the lights then ends up at the configuration mentioned above: 4 red lights down the right side, all blue lights on along the bottom, and a non-blinking red power light.
I have followed the troubleshooting advice at https://myproducts.drobo.com/article/AA-01649 : “What should I do if my Drobo storage device keeps rebooting?”
And I have followed the instructions from there to test the power supply.
The last part of the “reboot” issue instruction states: “Without drives installed the Drobo device should boot to the following condition: Top (or left) drive light is solid red, power light is Green, all other lights off. Drobo Dashboard should see your Drobo device.”
It get to that point for about 10 seconds, with the “Top (or left) drive light is solid red, power light is Green, all other lights off.” During this time, Drobo Dashboard still does not see my unit. And then it reboots and the cycle starts all over again.
The final bit of advice based on the above scenario is “If Drobo continues to reboot without drives installed, contact Support.” Which I did, supplying all the diagnostics info. But since I purchased this unit used…well, I’m SOL, unless one of you folks on this forum can help in some way.
Thanks in advance for any suggestions you might have.
