First I want to apologize if this has been asked before, I did a bunch of googling but couldnt find the answer that worked for me.
I have 2 Dell R820s, firmware and BIOS has been updated. I keep getting a 'SCSI sense: Deferred error: MEDIUM ERROR asc:11,5 (L-EC uncorrectable error) I have tried every possible combination of Disks, HHDs SSDs, 6gbps, 12gbps, I have formatted the disks with 512 and 4096. I have an LSI IT mode RAID controller. I have tried booting from virtual media, USB flash, DVD.
I have replaced the LSI card, The Disk backplane, the SAS cables.
I took a pair of disks that I had it already installed on and put them in one of the servers and it boots fine. It will just not for the life of me install.
I have been trying to install the most recent release of Cobia, 23.10.2, I even went back to an old version of FreeNAS 11.3.
Still not joy, I am at the end of my teather with trying to figure it out, any help would be greatly appreciated.
