Testing And Restoring Firmware On Switches; Testing A Different Firmware Version On A Switch - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Testing and restoring firmware on switches

Typically, users downgrade firmware after briefly evaluating a newer (or older) version and then restore the
original version of the firmware. Testing a new version of firmware in this manner ensures that you do not
replace existing firmware because the evaluated version occupies only one partition on the switch.
TIP: When you evaluate new firmware, make sure you disabled all features that are not supported by the
original firmware before restoring to the original version.

Testing a different firmware version on a switch

To test a different firmware version on a switch:
1. Verify that the FTP or SSH server is running on the host server and that you have a user ID on that
server.
2. Get the firmware file from the HP website at
server.
3. Unpack the compressed files preserving directory structures.
The firmware is in the form of RPM packages with names defined in a .plist file, that contains specific
firmware information and the names of packages of the firmware to be downloaded.
4. Connect to the switch and log in as admin.
5. Issue the firmwareShow command to view the current firmware.
6. Issue the firmwareDownload -s command to update the firmware and respond to the prompts as
follows:
switch:admin> firmwareDownload -s
Type of Firmware (FOS, SAS, or any application) [FOS]:
Server Name or IP Address: 192.168.32.10
Network Protocol (1-auto-select, 2-FTP, 3-SCP) [1]:
User Name: userfoo
File Name: /home/userfoo/6.0.0

Firmware is being downloaded to the switch. This step may take up to 30 minutes.

The switch performs a reboot and comes up with the new firmware to be tested. Your current switch
session automatically disconnects.
7. Connect to the switch, log in as admin, and issue the firmwareShow command to confirm that the
primary partition of the switch contains the new firmware.
You are now ready to evaluate the new version of firmware.
IMPORTANT:
otherwise, continue to
download operations.
8. Commit the firmware.
a. Issue the firmwareCommit command to update the secondary partition with new firmware. Note
that it takes several minutes to complete the commit operation.
b. Issue the firmwareShow command to confirm both partitions on the switch contain the new
firmware.
Stop! If you want to restore the firmware, stop here and skip ahead to
