HP MSA2312fc replace defect controller (dual-controller setup) with 2nd hand controller

chupkes — Wed, 25 Jun 2014 10:06:56 GMT

We have a HP MSA2312fc setup, with two controllers. Controller A is malfunctioning. Since the MSA is out of warranty, we've bought a 2nd hand controller (AJ798A) from Ebay.

We do not know whether this 'new' controller still has a previous configuration on it. We certainly do not want a previous configuration to overwrite the configuration of our controller B, obviously.

I have two questions:

- Is there a possibility that the configuration of our 'new' controller will overwrite the configuration of our current active controller (B)?

- How can we flush the configuration of the 'new' controller? We don't have a spare MSA laying around..

Thanks in advance!

Configuration is saved in hard disk drives. Hence, there should not be issue of replacing with a used controller. But, replacement controller should have same spare part number.

Make sure you replace it online while the array is running. Since some settings are stored in the controller, the active will clone the config to the second.
