hpacucli not detecting HP Smart Array Controller


In some cases hpacucli is not detecting the HP Smart Array Controller, in my case it was a HP P420 controller.

Error: No controllers detected.

You can solve this issue by loading the sg module:

# modprobe sg

You’ll see now that the controller is detected:

=> ctrl all show

Smart Array P420 in Slot 2 (sn: XXXXXXXX)
