To check the health of an Adaptec RAID array in Linux, you can use the arcconf command. The arcconf command is a utility that is provided with Adaptec RAID controllers and can be used to manage and monitor the status of the RAID array.
Here's an example of how to use the arcconf command to check the health of an Adaptec RAID array:
arcconf getconfig 1 | grep Status
This will display the status of the RAID array on controller 1.
The arcconf command has many options that allow you to perform various tasks, such as creating and deleting arrays, configuring drives, and performing online capacity expansion. You can use the arcconf command with the --help option to display a list of available options.
