You need to login to the hardware interface. For example Dell uses the DRAC, whictch can be accessed through a web GUI. On SUN servers you use a ILOM or ALOM, which is also accessible though a web GUI.
In the GUI there will be an option to light up the HD.

Hi all,
I have encountered the issue with the hard disk, the disk is failed and need to replace by the new one.

authconfig-gtk
AUTHCONFIG-GTK(8) System Manager's Manual AUTHCONFIG-GTK(8)
NAME
authconfig-gtk, system-config-authentication - GUI utility for configuring user identity and system authentication services
SYNOPSIS
authconfig-gtk [--nox] [--updateall] [--firstboot]
DESCRIPTION
authconfig-gtk provides a simple graphical user interface for configuring user identity and system authentication services. It provides
basic configuration options to handle NIS, LDAP, Kerberos 5, and Winbind client configuration.
OPTIONS
If the --nox option is specified, authconfig command line utility is run instead of the GUI.
The --updateall option forces overwriting of all configuration files not only the files affected by the changes made in the user interac-
tion with the GUI. This option can be useful in case the configuration files are broken by manual editing.
The --firstboot option is to be used only when firstboot utility runs the GUI during the first setup of the system after installation.
RETURN CODES
authconfig-gtk returns 0 on success, non zero on error.
