How to verify Hard Drive status through arcconf ?

Description: 

The article will guide you how to check hard drive healthy. In this article, we use the MicroSemi RAID card as example. You can use arcconf CLI commands to get information.  

Target Audience: 

People who have basic knowledge of Linux, RAID and how to run CLI command in a Linux shell.

Requirement:

Environment with available MicroSemi RAID card and please download arcconf utility from MicroSemi web site: (Please follow the SLA from MicroSemi)

Step:

• Download the arcconf utility and use the suitable arcconf command on OS, switch to root mode and run the command in Linux mode.
• Check the controller number.

# ./arcconf list
Controllers found: 1

• List Physical device information only and filter the keyword of "state" & "Array".

# ./arcconf getconfig 1 PD | grep -i 'state\|Array'
State : Predictive Failure
