Installing firmware New firmware becomes available periodically either on CD-ROM or from the HP web site. Installing firmware on a switch involves the following steps: 1. Downloading the firmware image file to the switch. 2. Unpacking the firmware image file. 3. Activating the new firmware. The activation can be disruptive or non-disruptive. See "Non-disruptive activation" on page 43. The firmware install and the image install commands automate the firmware installation process and perform a disruptive activation as described in "One-step firmware installation" on page 44. To perform a non-disruptive activation, see "Custom firmware installation" on page 45. 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 inter-switch links (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 Host Bus Adapter (HBA) configuration changes. Install firmware on one switch at a time in the fabric. If you are installing firmware on one switch, wait 2 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, Simple SAN Connection Manager sessions and QuickTools sessions are automatically reconnected. However, Telnet sessions must be restarted manually. 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. 8/20q Fibre Channel Switch command line interface guide 43
