HP Moonshot Switch Module CLI Command Reference
initiate failover
This command forces the backup unit to take over as the management unit and perform a “warm restart” of
the stack. On a warm restart, the backup unit becomes the management unit without clearing its hardware
tables (on a cold restart, hardware tables are cleared). Applications apply checkpointed data from the former
management unit. The original management unit reboots.
If the system is not ready for a warm restart, for example because no backup unit has been elected or one or
more members of the stack do not support nonstop forwarding, the command fails with a warning message.
The
movemanagement command (see page 26) also transfers control from the current management unit;
however, the hardware is cleared and all units reinitialize.
Last Startup Reason The type of activation that caused the software to start the last time:
• “Power-On” means that the switch rebooted. This could have been caused by a
power cycle or an administrative “Reload” command.
• “Administrative Move” means that the administrator issued the
movemanagement
command for the stand-by manager to take over.
• “Warm-Auto-Restart” means that the primary management card restarted due to
a failure, and the system executed a nonstop forwarding failover.
• “Cold-Auto-Restart” means that the system switched from the active manager to
the backup manager and was unable to maintain user data traffic. This is usually
caused by multiple failures occurring close together.
Time Since Last Restart Time since the current management unit became the active management unit.
Restart in progress Whether a restart is in progress.
Warm Restart Ready Whether the system is ready to perform a nonstop forwarding failover from the
management unit to the backup unit.
