lunareset

The lunareset utility allows you to reset an HSM that has become unresponsive, without having to reboot the host computer. This command does not affect the contents of the HSM.

NOTE   On Linux clients, lunareset is installed in the /usr/safenet/lunaclient/sbin directory.

Syntax

Linux	lunareset <dev_path> [-F | --function-level-reset] [-h | --help] [-v | --verbose]
Windows	lunareset <dev_path> [-h|--help] [-v| --verbose]
