MSA Controller Replacement – Hewlett Packard Enterprise Community
May I ask what problem you are seeing? You dont need to worry about swapping the cache module. You can see the messages at the display. Contact Email us Tell us what you think.
We are currently on firmware version 7. You lost read cache but write cache is mirrored to Controller B.
Do I need to worry about swapping out the cache module if I shut down all the systems and wait 10 minutes for the cache to write to disk? Controller A reboots after Mda1000 sync.
The SAN configuration is locate on the disk drives so we should not lose our configuration during this process. We are planning on replacing the controler this weekend and wanted to see if anyone had some advice or insight to give. From my understanding the controller replacement is hot swappable and should not affect production.

If there is a firmware mismatch, controller B will synch his FW to controller A because he is the master controller at this moment. We are conyroller problems with our MSA controller redundancy, which HP support thinks is due to a bad controller controller A. Is the controller replacement really that easy? MSA was retired 5 years ago, it’s time to look forward.
Check twice your redundancy is set for all systems. Why not upgrade firmware before to be in more control? The new controller A is suppose to have the new FW version 7. If you shut down your servers then you can wait 5 minutes to change Controller A.
