Hello gurus can someone point me in the right direction or maybe solve this issue for me. I had a drive (12TB) go disabled red x (Drive 6). I try to renabled it and to get it back online but couldn't get it back to green, I beleive the drive has read errors so I replaced the drive with a 20TB WD Red that I purchased and unfortuantly my noobness and stupidity did soemthing while I was trying to get the disabled 12TB to renable and UNRAID forced me to preclear and format the new drive thus losing 12TB of data. I rebooted before running diagnostics which was dumb of me, but honestly, I was worried about and focused on the 12TN of tv shows I was about to lose. Yes, I know I did soemthing and drive 6 should of rebuilt itself. So, I was running a parity check and after 12hrs parity checked paused and drive 4 became disabled, drives 1-6 are in the same disk shelf (EMC KTN-STL3 15 Bay connected to my server by SF-8088 to SF-8088 cable so I thought maybe it was a hardware issue, so I pulled the HBA, replaced the expander with a spare that I had and the SF-8088 to SF-8087 card and the cables. I moved the expander to a different PCI slot and reattched the SF-9-97 to SF-8087 cables in different positions. Long story short I ran another parity check, and it ran for roughly 20hrs and then paused and disk 4 went disabled again. I would lijke to rebuild my 12TB of shows back but as a parity check usually takes 3 days to complete, I would like to resolve the issue before I lcompletly corrupt 129TB of Movies and TV Shows.
I'm assuming it's either the HBA or the expander. Like the HBA is resetting itself all the time. Suggestions, is there a type or quality of cables I should buy?
