So here’s a little issue you might run into with an HP C7000 BladeSystem. In this scenario you have two Onboard Administrators which manage the Blade enclosure and all of it’s components. One is an active OA (Onboard Administrator) and one is passive.
You try to power on one of the blades and you get a power error and the red light flashes on front of the blade. You login to the OA and you see that everything is not good. There is a critical error with the power subsystem. You then check the enclosure info on the LCD and it tells you the other OA is the active one. Now that’s strange because the one you’re connected to thinks it’s the active one. How do you fix this?
Pull the bad OA, and call HP support and have it replaced. When you put the new OA in everything should go back to normal. Basically I had a bad OA that thought the power subsystem was not working but that wasn’t the case, it was the OA that was the issue.
Once the OA was replaced, all the blades powered up fine. Hope this helps!
