Linux Check Health of 3ware RAID Array

To check the health of a 3ware RAID array on a Linux system, you can use the tw_cli utility. tw_cli is a command-line interface for managing 3ware RAID controllers and arrays.

Here's an example of how to use tw_cli to display the status of all the arrays on the controller:

$ sudo tw_cli /c0 show

This will display the status of the arrays, including the array number, type, size, and other details.

You can also use tw_cli to display the status of a specific array. For example, to display the status of array 0 on controller 0, you can use the following command:

$ sudo tw_cli /c0/u0 show

Note: You will need to have the necessary privileges to run the sudo command.

It's also a good idea to periodically check the health of your RAID arrays to ensure that they are functioning properly and to identify any potential issues.

Note: The specific options and syntax for the tw_cli command may vary depending on your Linux distribution and version. Consult the tw_cli man page or documentation for your system for more information.
