R21xx-HP FlexFabric 11900 Fundamentals Configuration Guide

Non-ISSU upgrade procedure summary

To upgrade software from the CLI without using ISSU:

1. Download the upgrade software image file.

2. (Optional.) Preload the BootWare image to the BootWare.

If a BootWare upgrade is required, you can perform this task to shorten the subsequent upgrade

time. This task helps avoid upgrade problems caused by unexpected electricity failure.

If you skip this task, the device automatically upgrades the BootWare when upgrading the startup

software images.

The BootWare image preloaded into the BootWare does not affect the device running status.

3. Specify the image file as the startup software image file.

4. If you are upgrading a standalone device, reboot the device. If you are upgrading an IRF fabric,

reboot the entire IRF fabric.

5. Verify the upgrade.

Preparing for the upgrade

1. Use the display version command to verify the current BootWare image version and startup

software version.

2. Use the release notes for the upgrade software version to evaluate the upgrade impact on your

network and verify the following items:

{ Software and hardware compatibility

{ Version and size of the upgrade software

{ Compatibility of the upgrade software with the current BootWare image

3. Use the dir command to verify that all MPUs have sufficient storage space for the upgrade images,

and use the delete command to delete unused files. For more information, see "Managing the file

system."

4. Configure FTP and TFTP settings.

5. In standalone mode, download the upgrade image file to the root directory of the flash on the

active MPU. In IRF mode, download the file to the root directory of the flash on the global active

MPU.

For more information about FTP and TFTP configuration and operations, see "Configuring FTP" or

"Configuring TFTP."
