I was working on an HP P4300 Lefthand SAN solution and trying to create a management group when I got an error about an nvram card that is not normal, see screenshot.

When I run the All Tests at the diagnostics Tasks, the Cache Status was Corrupt.

I searched the internet for a solution and I didn’t find anything. I contacted HP about this problem and they send me an e-mail with the solution.

The solution is as follows. Go to the Storage tab on the node with the problem. Select Reconfigure RAID…

Note! This was a new HP P4300 device, brand new out of the box with no data on it. If there is data on it, please contact HP for another solution.

Select the correct RAID configuration, in my case RAID 5. Acknowledge the warning. This takes a few minutes, and when it finishes, go to the diagnostics again. Do the same diagnostic test and now the corrupt cache error message is gone. Problem solved.
