I hope you can help me. I purchased this controller "ServeRAID M5210"
https://lenovopress.lenovo.com/tips1069-serveraid-m5210-sas-sata-controller
I am trying to use it in a custom build home lab server. However I do not get it working. I see the controller being recognized during boot, but I am not able to access the controller bios. Also in the OS it is shown as faulty. I tried Windows, Linux and ESXi. No luck.
Is it possible that this controller only works with Lenovo / IBM servers?
Many thanks for your help.
