Hello, on January 10th, i got a disk 3 disabled drive error and none of the files were accessible.

The logs (attached) were showing disk read errors across all disks.

I shut down the server, replugged all SATA cables, rebooted and did not see any additional errors.

I removed Disk 3 --> Readded it and rebuilt the drive.

Everything seems to have worked fine,

Today, i noticed similar errors (in log).

I noticed this when i got a UPS error with "power failure" although we didn't have a power outage and for some reason a parity check kicked in. (don't worry auto correct is not enabled)

There is no apparent issue with the server right now, all drives are green, files seem to be accessible. I suspect may be this is related to my LSI 9207-8i PCIe card but i have to check if those hard drives are connected to it or whether they are connected straight to the motherboard.

Any advise on how to proceed?

Thanks, i've attached it.

mobo controller has cache, parity, disks 6, 7, unassigned serial ending ZLZC. All other on LSI

Thanks, based on the errors, does that mean that my LSI is failing, or cables? (There are two breakout cables)... Could it be the port on the motherboard?

looking for the best way to eliminate the possible issues one by one. I found it bizarre that it stated there was a power failure when we didn't have one.

Rebooted and since it wasn't shutdown cleanly you got parity check. I assume BIOS is configured to boot on power restore, so seems like it must have lost power briefly.

Could it be overheating?

The unclean shutdown concerns me, my UPS has ample time to shutdown the server and is configured to do so. I'm going to test it and ensure the battery is still in google health, and then it may indicate that maybe the power supply (?)

The LSI overheating - All the fans are still spinning in the case. I'll remove the cover from the case and monitor the next few days, although i've had it running just fine during heat waves. Worth a look though.

often those things need active cooling directly on the card if not installed in a server chassis with high airflow.

Using thing cards in normal consumer PC cases definitely requires them to have a fan blowing directly on them

HBA issue, make sure it's well seated and sufficiently cooled. You can also try a different PCIe slot if available.
