As an option, before starting a firmware download, HP suggests that you connect the switch with a
console cable to a computer that is running a session capture. The information collected may be useful if
needed for troubleshooting.
Summary of the upgrade process
The following summary describes the default behavior of the

command (without
options) on the SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Switch 4/32.
• Issue the
firmwaredownload
command.

SAN Switch upgrade procedure
For the SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Switch 4/32, the upgrade
process first downloads and then commits the firmware to the switch. While the upgrade is proceeding,
you can start another telnet session on the switch and observe the upgrade progress if you wish.
NOTE: After you start the process, do not enter any disruptive commands (such as
reboot
) that
interrupt the process. The firmware download and commit process takes approximately 15 minutes. If
there is a problem, wait for the time-out (30 minutes for network problems; 10 minutes for incorrect IP
address). Disrupting the process can render the switch inoperable and require you to seek help from
Customer Support.
Do not disconnect the switch from power during the process; the switch could become inoperable upon
reboot.
Use the following procedure to upgrade firmware for the SAN Switch 2/8V, SAN Switch 2/16V, SAN
Switch 2/32, and SAN Switch 4/32:

2. Obtain the firmware file from the HP StorageWorks web site at
http://www.hp.com/country/us/eng/prodserv/storage.html and store the file on the FTP server. Verify that
the FTP service is running.
