Installing Firmware; Non-Disruptive Activation - HP AK241A - StorageWorks 8Gb Simple SAN Connection Cli Manual

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
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
To perform a non-disruptive activation, see

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.
