Hotreset - HP StorageWorks SN6000 Command Line Interface Manual

hotreset

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 may
take a few minutes. To save the event log to a file before resetting, enter the set log archive
command.

Notes You can load and activate firmware upgrades on an operating switch without disrupting data traffic
or having to re-initialize attached devices. If the non-disruptive activation fails, you will usually be
prompted to try again later. Otherwise, the switch will perform a disruptive activation. Verify that the
current firmware version supports the installation and non-disruptive activation of the new firmware
version. For information about compatible firmware versions, see the Firmware Release Notes.
To ensure a successful non-disruptive activation, you should first satisfy the following conditions:
• No changes are being made to switches in the fabric including installing firmware, powering up,
powering down, disconnecting or connecting ISLs, and changing the switch configuration.
• No port on the switch is in the diagnostic state.
• No zoning changes are being made on the switch.
• No changes are being made to attached devices, including powering up, powering down,
disconnecting, connecting, and HBA configuration changes.
• No more than two Simple SAN Connection Manager sessions are open.
Ports that change states during the non-disruptive activation are reset. When the non-disruptive
activation is complete, Simple SAN Connection Manager sessions, QuickTools sessions, and
Enterprise Fabric Management Suite sessions are automatically reconnected. However, Telnet
sessions must be restarted manually.
This command clears the event log and all counters.
TIP: After upgrading firmware that includes changes to QuickTools, a QuickTools session that was
open during the upgrade may indicate that the new firmware is not supported. To correct this, close
the QuickTools session and the browser window, then open a new QuickTools session.
