Hotreset command
Description 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
event log. After the pending firmware is activated, the configuration is recovered. This process takes
less than 80 seconds. To save the event log to a file before resetting, refer to the Set Log command.

Notes You can load and activate 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 version that supports upgrading to the new 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 and then change states, will be reset.
When the non-disruptive activation is complete, McDATA Web Server sessions reconnect
automatically. However, Telnet sessions must be restarted manually.
This command clears the event log and all counters.
