December 24, 20214 yr I've had a Unraid server running smooth on a DL380P Gen8 for two years. Decided to retire the server and build a 24 bay Threadripper server. Transplanted the HBA (HP H220 IT-Mode), cache disks and array to a SuperMicro 846 24 bay chassis with BPN-SAS2-846EL1 backplane. Ran that for a couple weeks with no issues. Recently purchased a dozen 4TB disks cheap with mixed but mostly low hrs. (All pass smart test) Running into a lot of read errors on the bottom 12 bays. Troubleshooting Steps to date: - Swapped out H220 for a LSI 9207-8i - P20.00.07.00-IT. - Swapped out the backplane. - Tried 3 different SFF8087 cables. I've ran out of ideas. Thanks. cerberus-diagnostics-20211223-2332.zip

December 24, 20214 yr Author Thanks for the info @JorgeB Pulled the 12 disks from the array and started the format process on the 1st disk. This is going to take some time to go through 12 of them but I at least have my existing array back up and running.
