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 command for .tar files, the gunzip command
for all .gz 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 5.3.x.zip, it expands
into a directory called 5.3.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 5.3.x
directory.

Performing firmware download on switches

4/16 SAN Switch and 4/8 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade
4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32,
SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN Switch, 4/32B SAN Switch and 400 MP Router
maintain primary and secondary partitions for firmware. The firmwareDownload command defaults to
an autocommit option that automatically copies the firmware from one partition to the other.
You should not override autocommit under normal circumstances; use the default. Refer to
restoring firmware-on

Summary of the firmware download process

The following summary describes the default behavior after you enter the firmwareDownload command
(without options) on 4/16 SAN Switch and 4/8 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class
BladeSystem, Brocade 4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 2/8V, SAN Switch
2/16V, SAN Switch 2/32, SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN Switch and 400 MP Router
models:
• The Fabric OS downloads the firmware to the secondary partition.
• The system performs a high-availability reboot (haReboot). After the haReboot, the former
secondary partition is the primary partition.
• The system replicates the firmware from the primary to the secondary partition.
• Software application (SA) software is upgraded only when firmwareDownload is issued with the
SA option. Refer to the application's manual for further information.
