RAID Controller Battery Failure and Corruption

[ITGURU]

Twice now i've had an issue whereby when a RAID Controller battery has failed it has caused minor issues. The first time it messed up SQL server and had data corruption so had to restore from a previous backup.

 

Now, i recently had issues with SOLUS 3 not working properly saying it hadn't downloaded all the files and did i want to download them again, ending up in a constant loop.

 

Capita determined the issue (for whatever reason) was because solus didn't like the repository share on the data drive - bearing in mind i downloaded other updates and deployed on the same day which were fine, they moved the solus repository to the C drive and then it worked.

 

It seems when the raid controller batteries fail it causes weird issues like this. I'm guessing if the server suddenly decides the battery has failed then any data in the cache that hasn't been written will cause corruption?

 

Should this happen? All servers are up to date with raid controller firmware/driver and all disks on latest firmware too.

How old are the servers? I've never had a controller battery fail and I've always run my servers for no less than 5 years.

This one is 6.5 years old and first time battery swap, i've had HPs run until 10 years before decommissioning and always swapped the battery at least once.

Interestingly I have 3 HP severs where 2 of they are reporting battery issues - I'm guessing these are approx 8 years old as i have been here 5 years and they in place when I arrived.

 

Thankfully I am replacing the batteries either tonight or tomorrow in all 3 HP servers.

I have had battery fails on a few servers over the years, funnily enough I have one with the error message now, but it has never caused me an issue. Our servers are all DELL, and I normally get a message on the screen that the RAID card has switched to write through or something similar.

 

Generally get the error after about 7 years but have had it on much newer servers.

I’ve had battery failures on HP servers, but they’ve handled it smartly and not lost data, just popped up an alert in the Storage Manager.
