Assuming that you have a SmartArray hardware RAID controllar and have installed the HP RAID configuration tools, run this command as root:
hpacucli ctrl all show config detail
This will display all the configuration information of the hardware RAID controller, including the configuration and health of any mirrors or other RAID sets.
But HP has many server models and many different RAID controller models: the hpacucli command will cover the most common ones, but not all. To get a more accurate answer to your question, please specify the exact model of your server and RAID controller.
The built-in disk controller in Proliant DL360 Gen9 is Dynamic Smart Array B140i, and it apparently uses a different tool called "ssacli" instead of "hpacucli", but the command syntax looks very similar to hpacucli.
You can download it from HP Enterprise support pages:

Before installation, please read:
https://downloads.hpe.com/pub/softlib2/software1/pubsw-linux/p1857046646/v122802/ssacli-3.10-3.0.x86_64.txt
Note: the installation instructions say that in RHEL 7.1, the "sg.ko" kernel module must be loaded or else the tool won't detect the devices or controllers properly.
Instructions for use can be found here:
http://h20566.www2.hpe.com/hpsc/doc/public/display?docId=c03909334
Please see page 57 and onwards. In particular, for verifying the current configuration, you'll want the showcommand, described on page 61.
