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 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” on page B-52.

Notes You can load and activate version 4.2.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, 4.0, 4.1, or 4.2.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.
