Any server experts out there?
I got a error message on my server's front display showing "E1810 - Hard Drive 0 Fault - Review and Clear SEL" along with "E1211- RAID Controller Battery Failure". Haven't noticed any day-to-day changes with the system. How urgent is this matter and what's fixing the problem look like? I've already backed up everything externally.
Do you have raid 1 or raid 5 configuration?
Where do I find this information?
It's usually in the bios or if you bought it pre-configured it will have it on the invoice. Raid 1 is mirroring, so you have identical copies on 2 separate drives. The error means one of those drives is failing or has failed. The reason you don't have any change is because you still have a full copy on the drive that didn't fail.
Raid 5 is a parity bit, but you have to have 3 drives for this setting. Having that external backup makes replacing that failed drive less urgent.
Yeah, it looks like there's just two drives (C:/D:) but it doesn't look like it's mirrored?? The D: drive looks to have full capacity with nothing on it?
That being said, I have no idea what mirroring looks like but assume it is the same data on each drive? I know virtually nothing about servers btw.. so with data that is important backed up to flashdrive it's less urgent?
When a drive is failing it's usually a mechanical issue with the drive, which means data can't be read. So there may be a flaw when trying to read it, which makes it look empty/full.
Yeah, mirroring is 2 exact copies of each other, it's just redundancy for your data.
When a drive fails with raid 1 you still have your data, it just means if the good drive fails there isn't another backup. While it's important to replace that failed drive, having an external copy(flash drive) gives you the redundancy of multiple copies.
