PERC 6/i Integrated disk failure issues
Hello,
My company recently picked up 3 (gen 10) PowerEdge R900 servers each with the Perc 6/i controller. As these servers are being used for video recording we replaced all drives with 5x 2TB Seagate Pipeline HD SATA drives in a RAID 5 configuration(no hot spare). All drives have the same firmware.
I have now had 4 drives on 2 separate systems report critical drive (E1810) failures. In 3 of the cases either reseating the drive into the chassis, or swapping it into one of the other servers, clearing foreign config, and letting the drives rebuild fixed the issue. I am seeing 5/24/00 Sense errors but looking that up it seems to be software related. Is this a backplane problem, a controller problem, or are these HDDs actually having issues? Is there a way to do individual drive diagnostics without damaging the Virtual Disks?
Thanks,
George

It is more likely the drives are not compatible. Dell does not support them ... did you check with Seagate for compatibility?

If they are not 'compatible' why do all the others function normally? 13 of these drives have been running for 3 months now with no issues.

Hard to say ... the nature of incompatibility is unreliability and unpredictability. Where do you even start?
Check firmware levels. Small differences in the interface can make a big difference when they aren't designed to work together. Normally, you are better off making sure both the system firmware and drive firmware are up to date, but you'd need to do some testing to make sure that newer firmware isn't causing the issue.
