I have an Dell Poweredge R720 with a Dell H710P mini (D1) RAID card.
I wanted to run zfs so I found a way to flash the RAID card, https://fohdeesha.com/docs/perc/, first time around I missed the part where I would write back the SAS address to the card. Everything else worked just fine with the flashing.
So I bought 10 900 GB Seagate SAS disks, put them into the server, tried to make a zpool of them, failed. Error 1.
Went to CLI ran fdisk /dev/sdX on every disk, 9 out of 10 gave me the same error: Input/output error while writing out and closing file system.
Bewildered I moved them to my older HP server, with an intact unflashed RAID card, tried them there, 6 out of 8, LED lights went orange. In the BIOS I was only able to see 2 disks.
At this time, I contacted the seller, told him the story. He says to me that the disks was destroyed when I tried to make the zpool with a, his words, faulty raid card.
After this a lot of time went into to narrow down the error. Reflashing the card, both with IT/HBA firmware and writing back the Dell firmware. I also tried to write zeros to all the disks. All in all in the end I had 4 out of 10 disks working (A tid bit, before sending me the disks he tried 4 disks and they were all working...).
At this time I asked the seller to give me the money back and I would send him the disks.
He refuses, blaming my handling of the disks to be the fault here.
I just need to get a reality check here.
Can a RAID card, flashed or not, destroy a disk? Rendering it semi-working?
