Kernel parameters

You configure the suspend and resume support by adding parameters to the kernel parameter line.

Figure 1. suspend and resume kernel parameter syntax

1  resume=<device_node>?  no_console_suspend?  noresume
where:
resume=<device_node>
specifies the standard device node of the swap partition with the data that is required for resuming the Linux® instance.

This swap partition must be available during the boot process.

no_console_suspend
prevents Linux consoles from being suspended early in the suspend process. Without this parameter, you cannot see the kernel messages that are issued by the suspend process.
noresume
boots the kernel without resuming a previously suspended Linux instance. Add this parameter to circumvent the resume process, for example, if the data written by the previous suspend process is damaged.

Example

To use a partition /dev/disk/by-path/ccw-0.0.b100-part2 as the swap partition and prevent Linux consoles from being suspended early in the suspend process specify:
resume=/dev/disk/by-path/ccw-0.0.b100-part2 no_console_suspend
