Hotreset Command

Hotreset Command

Resets the switch for the purpose of activating the pending firmware without disrupting traffic. This command terminates all management sessions, saves all configuration information, and clears the alarm log. After the pending firmware is activated, the configuration is recovered. This process takes less than 80 seconds. To save the alarm log to a file before resetting, refer to the ”Set Log Command” on page B-44.

Authority	Admin session
Syntax	hotreset
Notes	You can load and activate version 4.0.x firmware on an operating switch without
	disrupting data traffic or having to re-initialize attached devices under the following
	conditions:
	„	The current firmware version is a 2.0, 3.0, or a 4.0.x version that precedes
		the upgrade version.
	„	No changes are being made to switches in the fabric including powering up,
		powering down, disconnecting or connecting ISLs, and switch configuration
		changes.
	„	No port in the fabric is in the diagnostic state.
	„	No zoning changes are being made in the fabric.
	„	No changes are being made to attached devices including powering up,
		powering down, disconnecting, connecting, and HBA configuration changes.

Ports that are stable when the non-disruptive activation begins, then change states, will be reset. When the non-disruptive activation is complete, SANsurfer Switch Manager sessions reconnect automatically. However, Telnet sessions must be restarted manually. This command clears the event log and all counters.
