Secondary Control Module redundancy has failed - PS6510
Hi all,
I'm hoping someone could possibly help.
We recently had the secondary controller replaced in our EOL PS6510 by third party support. Ever since the controller was replaced we get an email alert every 24hrs. I am now unable to fail back to the primary controller from the group manager.

Secondary Control Module redundancy has failed. Please contact a senior support representative (Ref: QNA42261 / CEMI0.0).
-----------------------------------------
When i attempt to perform a restart, a fail alert appears and I get the same error as i listed above.
No errors or alerts are present in the CLi.

Hello Brendan,
There are a couple possibilities I can think of right off the bat.
One, they didn't swap out the compact flash card from the old controller, and put it in the replacement controller. So the controller isn't booting up and connecting to the primary controller.
Two, they didn't swap out the CF card and the one in the replacement doesn't match the primary so failover cannot occur.
Three, the replacement controller is defective.
If you do a member select Member02 show controllers That will give you more information.
Regards,
Don

Hi Don,
Cheers for the information that was useful.
I personally do not have faith in the EOL support we are receiving (Non-dell support). They are advising we need to shut down the SAN which is not possible and I dont believe it's the solution.
Here's the output
member select Member02 show controllers

Hello Brendan,
Well I looked into that error and they are correct. The only resolution is a complete shutdown. Shtudown the servers. Power off the array for at least two minutes and bring it back up. That should resolve the issue.
Also, just FYI: Dell is now offering extended H/W only support up to 12 years from original ship date on arrays like the PS SANs.
Regards,
Don
