Bypass Equallogic PS4210 battery end of life check
The batteries on both controllers in my PS4210 have failed. I will order replacements, but in the meantime are there any early-boot serial terminal commands or environment variables (the ctrl-P interface) I can use to boot regardless? Some sort of bypass for the controller's battery health checks? My understanding is the battery is only used to perform write-back in the event that both power sources fail simultaneously. My PS4210 has its power supplies on two different PDUs on two different phases, with UPS, so that's a very low likelihood risk. It's much more important to me that I can run the unit in the meantime than keep it off until the replacement batteries arrive in a few days. Thanks!

Hi,
Unfortunately, I do not see a way to bypass the messages and to continue to boot.
Let us know if you have any additional questions.

Hello,
Josh is correct. There is no by-pass for the failed battery state. Since they also preserve any unwritten cache. I.e. on a controller failure or power loss. This is why the warning threshold is at least 3 months before they expire.
Regards,
Don

Ok, thanks for looking into it! I'm expecting replacements tomorrow so we'll just sit tight.

Is there a way to read the cache battery expiration date from the CLI?
I have a batch of replacement batteries I purchased that all timed out after a month and the provider doesn't believe the batteries (or at least the circuit modules) are old.
The batteries were marked by a recent manufacture date, but I don't believe that
My understanding is that the expiration date is set on the battery module at the time of manufacture.
Thanks in advance

Hello,
No, I am sorry there is not. You can see the status, good, warning, bad.
