Znyx Networks bh5700 manual Updating the Switch Firmware, BootLoader Firmware Upgrade

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.

zflash -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
