    Maintaining the C Series Hard Disks

    Purpose

    For optimum controller performance, verify the condition of the hard disks.

    Action

    On a regular basis:

    • Check the hard disk status LEDs to view information about the status of the hard disk.
    • To check the status of the hard disk, issue the show disk status command. The output is similar to the following:
      user@host> show disk status
