Enabling the Service

To start the kdump daemon at boot time, type the following at a shell prompt:

~]# chkconfig kdump on

This will enable the service for runlevels 2, 3, 4, and 5. Similarly, typing chkconfig kdump off will disable it for all runlevels. To start the service in the current session, use the following command:

~]# service kdump start
No kdump initial ramdisk found.                            [WARNING]
Rebuilding /boot/initrd-2.6.18-194.8.1.el5kdump.img
Starting kdump:                                            [  OK  ]
