I've configured a HP DL360 Gen 9 with 6 disks and raid 5 and i've installed RHEL 6.9 on it. 

I need to know, from command line, the status of every single physical disk so i could grep info to an appplication we are developing.

I've been in touch with several guides that suggested to use HPACUCLI command but after i've installed the package seems it does not found any controller.

with ctrl all show status or config it says:
No controllers found

More info on this server are:

HP SMART START STORAGE 2.65.7.0
Controller is the P440R 

I've some doubts about the compatibility of the hpacucli with this HW.

Anyone has an alternative idea on how to monitor the "single" disk status to understand if it is ok, there are some errors or it is faulty?

Regards
