February 18, 20242 yr Community Expert Solution Feb 17 05:11:11 unraid kernel: megaraid_sas 0000:07:00.0: Failed from megasas_init_fw 6540 Controller is failing to initialize, also note that it's using the megaraid driver, I would recommend flashing it to IT mode, just doing that may also solve the current issue.
February 20, 20242 yr Author That was the solution, I flashed the RAID card using this guide https://fohdeesha.com/docs/perc.html. It works very well if you still have a BIOS (legacy) motherboard. Thanks for the help.
