In Linux systems, you can use the following command to view RAID information:

  1. Running the command “cat /proc/mdstat” will display the status of all active RAID devices in the current system.
  2. Use the actual RAID device name in place of /dev/mdX in the command “mdadm –detail /dev/mdX” to view detailed information about a specific RAID device.
  3. Use the actual disk name in place of /dev/sdX to view RAID information for a specific disk.
  4. mdadm –query /dev/mdX: Retrieve basic information about the RAID device, such as RAID level and number of devices.
  5. mdadm –detail-platform: display information about supported RAID levels and RAID devices.

Please note that you may need to run these commands as the root user or a user with sudo privileges.
