SoftReboot White Paper

3 Configuration and Usage

SoftReboot functionality requires both "rbloader" and "uxex" DLKMs to be loaded. Upon installation

of the SoftReboot product, these two DLKMs are automatically configured to be loaded. Reboot

and shutdown utilities have been enhanced for SoftReboot and provide a new option, "-S", to

initiate a SoftReboot instead of normal reboot.

SoftReboot can also be invoked as part of swinstall SD command via a new option -x

softreboot. Using this new option, one can specify swinstall to perform a SoftReboot after

installation of patches that require a reboot.

swinstall –x softreboot=true –x autoreboot=true –s <kernel patch> \*

Synopsis for reboot and shutdown with the installation of bundle is changed as follows:

reboot –S [-t time] [-m message]:

Specifying "-S" option results in SoftReboot. It skips firmware and hardware

reinitialization unlike normal reboot. The other options [-t time] and [-m

message] are optional arguments.

[-t time] Specify what time reboot will bring the system down. Time can be the word

now (indicating immediate shutdown) or a future time in one of two formats: +number

and hour:min.

Refer reboot (1m) man page for more details.

shutdown –S [-r] [-y] [grace]:

Specifying "-S" option results in SoftReboot. It works like "shutdown -r"

except that firmware and hardware reinitialization is skipped. As part of this system

shutdown happens gracefully after which SoftReboot is performed.

The other options [-r] [-y] [grace] are optional arguments.

Refer shutdown(1m) man page for more details.
