Updating the Switch Firmware
Currently, the OpenArchitect and bootloader components are the only upgradeable firmware on
the Ethernet Switch Blade. Upgrading the IPMI software is not currently supported.
BootLoader Firmware Upgrade:
1. Download the bootloader image to a local system.
2. FTP the bootloader image from the local system to your switch.
3. Use the
zflash
command to write the new
elgoro/zmon
image into the boot flash
device. Be sure and use device 0, not device 1 or 2.
z
flash -d 0 <bootloader image name>
OpenArchitect Firmware Upgrade:
1. Refer to the HP bh5700 14-Slot Blade Server Installation Guide, Chapter 6, 14-Slot Shelf
Startup, Validating and Updating Your Firmware for instructions on how to gain access
to firmware updates for the HP bh5700 14-Slot Blade Server.
2. Use telnet, or preferably, attach a console cable to the switch, and login to the switch.
IMPORTANT: If you are connecting via
telnet
, be aware that the upgrade
process will reset the switch to the default IP address of 10.0.0.42, so you will have to
be able to reach 10.0.0.42.
3. Using the procedures referenced in Step 1, above, download the OpenArchitect image
upgrade to a local system.
4. Check for free space with the
df
command. The OpenArchitect image is very close to
the limit of free space available on a default system, so you may need to clear some space
prior to downloading the new OpenArchitect image to the switch.
CAUTION: Do not remove the existing copy of
/usr/sbin/gated
(as suggested
below) until you have, in fact, determined that an OpenArchitect upgrade version is
available for downloading.
One of the easiest ways to create free space is to remove
/usr/sbin/gated
, as the
application will be replaced during the update procedure. Once you have enough free
space, proceed.
5. From the switch console,
ftp
the new OpenArchitect image from the local system to
your switch.
The switch has two flash devices available: device 1 and device 2. Use the
zflash
command to write the new OpenArchitect image into the first flash device.
IMPORTANT: Make sure that Surviving Partner is not running before using
zflash
. The delays incurred while
zflash
writes the flash can cause the
