FreeBSD Check The Health of Adaptec RAID Array

To check the health of an Adaptec RAID array on FreeBSD, you can use the arcconf command-line utility, which is part of the Adaptec Storage Manager software package. This utility allows you to view the status of your RAID array, as well as perform various tasks such as rebuilding or resyncing a failed drive, creating or deleting arrays, and more.

To check the health of your Adaptec RAID array, follow these steps:

1. Make sure the Adaptec Storage Manager software is installed on your FreeBSD system. You can install it using the pkg package manager:

# pkg install adaptec-storage-manager

2. Once the software is installed, you can use the arcconf command to check the status of your Adaptec RAID array. The syntax for this command is:

arcconf GETCONFIG 1 LD

This will display the configuration and status of your Adaptec RAID array. The 1 indicates the controller number, and the LD (logical drive) parameter tells arcconf to display information about the logical drives on the controller.

3. Look for the State field in the output. If it says Optimal, your Adaptec RAID array is healthy. If it says Failed, one or more drives in the array have failed and you will need to rebuild or replace the failed drives.

Here is an example of the output you might see when running arcconf GETCONFIG 1 LD:

If you need more information or want to perform specific tasks on your Adaptec RAID array, you can use the arcconf utility's many other options and parameters. You can find more information about arcconf in the Adaptec Storage Manager documentation or by running arcconf help on the command line.
