I recently got my system back to stable after some bad sata cables caused several drives to fail simultaneously (thankfully no critical data lost!). After replacing the cables and returning things to stable I decided to upgrade my 2x 8TB parity drives to 2x 14TB drives after the recent BBY sale. After installing the drives and starting parity rebuild and preclear on the old 8's I came back the next day to find that parity was only building on one of the drives and the other was disabled. I decided to let parity continue building on the one and let the preclears finish.
Once that was done I stopped the array and tried to re-add the "disabled" parity drive but it didn't show up... Strange. OK, well lets add the 8TBs to the array for now. That worked fine.
Decided to restart the system to try adding the second parity drive. Same basic behavior. After a while it failed and disabled it self. I should also mention that during this time I've started to notice long boot times, however not every boot is long. Also sometimes the array takes forever to mount drives, but again, not always.
I started to suspect more hardware issues so I monitored the boot sequence. But other than not always catching all 3 LSI screens (I have 3 LSI cards) I'm not seeing anything. Even when I don't see all three LSI screens during boot every drive is still showing up (except the 14's occasionally as stated).
Now these are shucked drives, however I'm in a Storinator chassis so every drive bay is routed through molex power so that shouldn't be an issue.
I did update my BIOS. I want to check the LSI BIOS but I'm not sure how. I'm attaching my diagnostics and looking through them myself but I'm hoping someone here can help me out.
ETA: Oh, I've also tried moving them to other bays with no luck.
