BLADEOS 6.3 Application Guide

Updating the Switch Software Image

The switch software image is the executable code running on the GbESM. A version of the image ships with the switch, and comes pre-installed on the device. As new versions of the image are released, you can upgrade the software running on your switch. To get the latest version of software available for your GbESM, go to:

http://www.ibm.com/systems/support

From the BLADEOS CLI, use the /boot/cur command to determine the current software version.

The typical upgrade process for the software image consists of the following steps:

￿Place the new image onto a FTP or TFTP server on your network, or on a local computer.

￿Transfer the new image to your switch.

￿Select the new software image to be loaded into switch memory the next time the switch is reset.

Loading New Software to Your Switch

The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you load new software, you must specify where it should be placed: either into image1, image2, or boot.

For example, if your active image is currently loaded into image1, you would probably load the new image software into image2. This lets you test the new software and reload the original active image (stored in image1), if needed.

Caution—When you upgrade the switch software image, always load the new boot image and the

!new software image before you reset the switch. If you do not load a new boot image, your switch might not boot properly (To recover, see “Recovering from a Failed Upgrade” on page 10).

To load a new software image to your switch, you will need the following:

￿The image and boot software loaded on a FTP or TFTP server on your network. For example:

￿Boot file: GbESM-1-10U-6.3.1.0_Boot.img

￿Image file: GbESM-1-10U-6.3.1.0_OS.img

Note – Be sure to download both the new boot file and the new image file.

￿The hostname or IP address of the FTP or TFTP server

￿The name of the new software image or boot file

Note – The DNS parameters must be configured if specifying hostnames.
