NAME

       sanlk-reset - host reset program

SYNOPSIS

       sanlk-reset [OPTIONS] action lockspace_name ...

DESCRIPTION

       The  sanlk-reset  program  sets  events  in  specified  sanlock  lockspaces.  Events are defined to cause
       sanlk-resetd on another host to:
       - use wdmd/watchdog to reset the host
       - use /proc/sysrq-trigger to reboot the host

       Both hosts must be operational and have continued access to a common lockspace for the reset  request  to
       succeed.   After  setting  the  event,  the  sanlk-reset  program monitors the host status in the sanlock
       lockspace until the target host is dead.

       The sanlk-reset program can also be run on the same host as sanlk-resetd to update which  lockspaces  the
       local sanlk-resetd is watching for events.

       The  event  is  set  in  each  lockspace specified.  The target host may have a different host id in each

       --resource-mode, -R 0|1

   Update the local sanlk-resetd

       to watch new lockspaces for reset events:
