Non-Disruptive Activation - Qlogic SANbox 5600 Series Interface Manual

Non-disruptive Activation

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. A disruptive activation
interrupts Fibre Channel data traffic on the switch, while a non-disruptive
activation does not. For information about non-disruptive 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 powering up,
powering down, disconnecting or connecting ISLs, changing switch
configurations, or installing firmware.
No port on the switch is in the diagnostic state.
No Zoning Edit sessions are open on the switch.
No changes are being made to attached devices including powering up,
powering down, disconnecting, connecting, and HBA configuration changes.
For a fabric in which one or more switches are running firmware prior to
version 7.4, only one Enterprise Fabric Suite 2007 session can be open.
Install firmware on one switch at a time in the fabric. If you are installing firmware
on one switch, wait two minutes after the activation is complete before installing
firmware on a second switch.
Ports that change states during the non-disruptive activation, will be reset. When
the non-disruptive activation is complete, Enterprise Fabric Suite 2007 and
QuickTools sessions reconnect automatically. However, Telnet sessions must be
restarted manually.
NOTE:
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.
