Checking connected switches

If the switch to be upgraded is running version 4.1.x (or later), it is recommended that all switches directly
connected to it be running versions no earlier than 2.6.1, 3.1.x, or 4.1.x. If some connected switches are
running older firmware, upgrade them to
before upgrading firmware on your switch.
IMPORTANT:
OS release notes for the recommended firmware versions. Access the most up-to-date Release Notes and
the latest supported firmware from http://www.hp.com.
NOTE: Please go to
es. 1. Connect to the switch and log in as admin.
2. Enter the version command. The following information is displayed:
• Kernel—Displays the version of switch kernel operating system.
• Fabric OS—Displays the version of switch Fabric OS.
• Made on—Displays the build date of firmware running in switch.
• Flash—Displays the install date of firmware stored in nonvolatile memory.
• BootProm—Displays the version of the firmware stored in the boot PROM.

Obtaining and decompressing firmware

NOTE: The following steps describe how to download firmware. Web retrieval procedures may be
subject to change.
To access the latest Fabric OS 5.2.x firmware, configuration files and MIB files go to the following HP web
site:
http://h18006.www1.hp.com/storage/saninfrastructure/index.html
You must decompress the firmware (using the UNIX tar or gzip command for all .gzip files, or a
Windows unzip program for all .zip files) before you can use the firmwareDownload command to
update the firmware on your equipment.
When you unpack the downloaded firmware it expands into a directory that is named according to the
version of Fabric OS it contains. For example, if you download and unzip Fabric OS 5.2.x.zip, it expands
into a directory called 5.2.x. When you issue the firmwareDownload command, there is an automatic
search for the correct package file type associated with your switch. Specify only the path to the 5.2.x
directory.
