Disabling console blanking / powersaving feature of the terminal console monitor

Jun 09, 2017

If you want to prevent the power saving feature of a monitor directly connected to a CAStor storage node, you can add the following kernel option to the APPEND line in either the syslinux.cfg file on the CAStor USB key or in the PXE boot configuration file:

consoleblank=0

This configuration parameter will tell the kernel to stop blanking the console. This feature defaults to 10 minutes. A value of 0 disables the blank timer.

Example:

label normal

kernel profiles/castor-live/kernel

append initrd=profiles/castor-live/fsimage

CONSOLEBLANK=0

ramdisk_size=128000

root=/dev/ram0
