Fabric OS 6.2 administrator guide 217
Obtain and decompress firmware
Firmware upgrades are available for customers on the HP website http://www.hp.com.
You must decompress the firmware before you can use the firmwareDownload command to update
the firmware on your equipment. Use the UNIX tar command for .tar files, the gunzip command for all
.gz files, or a Windows unzip program for all .zip files
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, when you download and unzip 6.2.0.zip, it expands into a
directory called 6.2.0. When you enter the firmwareDownload command, there is an automatic search
for the correct package file type associated with the switch. Specify only the path up to and including the
6.2.0 directory.
Firmware download on switches
The following switches maintain primary and secondary partitions for firmware:
• HP StorageWorks 4/8 and 4/16 SAN Switches
• HP StorageWorks 8/8 and 8/24 SAN Switches
• Brocade 4Gb SAN Switch for HP p-Class BladeSystem
• Brocade 4Gb SAN Switch for HP c-Class BladeSystem
• HP StorageWorks SAN Switch 4/32
• HP StorageWorks 4/64 SAN Switch
• HP StorageWorks SAN Switch 4/32B
• HP StorageWorks 8/40 SAN Switch
• HP StorageWorks 8/80 SAN Switch
• HP StorageWorks EVA4400 embedded switch module
• Brocade 8Gb SAN Switch for HP BladeSystem c-Class
• HP StorageWorks 400 Multi-Protocol Router
The firmwareDownload command defaults to an autocommit option that automatically copies the
firmware from one partition to the other.
NOTE: This section applies only when upgrading from 6.1.x to 6.2.0, or from 6.2.0 to 6.2.0. If you are
downgrading from 6.2.0 to 6.1.x, you must enter the firmwareDownload –s command as described in
”Test and restore firmware on switches” on page 227.
You should not override autocommit under normal circumstances; use the default. See ”Test and restore
firmware on enterprise-class platforms” on page 228 for details about overriding the autocommit option.
Switch firmware download process overview
The following default behaviors occur after you enter the firmwareDownload command (without
options) on HP StorageWorks 4/8 and 4/16 SAN Switches, HP StorageWorks 8/8 and 8/24 SAN
Switches, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade 4Gb SAN Switch for HP c-Class
BladeSystem, HP StorageWorks SAN Switch 4/32, HP StorageWorks 4/64 SAN Switch, HP
StorageWorks SAN Switch 4/32B, HP StorageWorks 8/40 SAN Switch, HP StorageWorks 8/80 SAN
Switch, HP StorageWorks EVA4400 embedded switch module, 8Gb Brocade, Brocade 8Gb SAN Switch
for HP BladeSystem c-Class, and HP StorageWorks 400 Multi-Protocol Router:
• 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 command is entered
with the SA option. See the application’s manual for further information.
