How to verify Hard Drive status under arrray mode through arcconf ?

Description: 

The article will guide you on how to check hard drives healthily. In this article, we use the Microsemi RAID card as an 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 commands in a Linux shell.

Requirement:

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

Adaptec - Adaptec Driver: Adaptec ARCCONF Command Line Utility v3.03.23668 Download Detail (microsemi.com)

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
----------------------------------------------------------------------
Controller information
----------------------------------------------------------------------
Controller ID : Status, Slot, Mode, Name, SerialNumber, WWN
----------------------------------------------------------------------
Controller 1: : Optimal, Slot 5, Mixed, ADV Adaptec ROC-8i, Unknown, 50123456789ABC00

Command completed successfully.

• Identify Raid card type, RAID level, Disk name & Logical Device Name(defined in RAID initial phase), and acceleration method.

# arcconf getconfig 1 |grep -E 'Controller Model|Functional Mode|Logical Device number|Disk Name|Array Number|RAID level|LD Acceleration Method|Logical Device name|Connector \#[01]|Connector Name|Functional Mode|No-Battery Write Cache'
