18 1 - OVERVIEW OF THE HP EFS WAN ACCELERATOR
IMPORTANT: Do not clear the data store before performing a software upgrade.
The following upgrade instructions assume that you have a network of 10 HP EFS
WAN Accelerators (HP EFS WAN Accelerator-1 through HP EFS WAN Accelerator-
10). Initially, you will upgrade three HP EFS WAN Accelerators (HP EFS WAN
Accelerator-1 through HP EFS WAN Accelerator-3).
To upgrade from 1.2 to
v2.1
1. Connect to the Management Console on each HP EFS WAN Accelerator.
2. Install the v2.1 image in the Setup: Software Upgrade page.
3. Save the current configuration in the Setup: Configuration Manager page.
4. Reboot the HP EFS WAN Accelerator in the Setup: Reboot Appliance page.
5. Connect to the CLI on each of the 3 HP EFS WAN Accelerators that you want to
upgrade.
6. At the system prompt, enter the following set of commands:
SH > enable
SH # configure terminal
SH (config) # peer 0.0.0.0 version min 5
SH (config) # peer 0.0.0.0 version max 5
SH (config) # write memory
This set of commands ensures that the v2.1 HP EFS WAN Accelerators can
communicate with all the v1.2 appliances in your network.
To take advantage of the v2.1 features, you need to configure the v2.1 HP EFS WAN
Accelerator
s to communicate with each other using the v2.1 protocol.
7. On HP EFS WAN Accelerator-1, at the system prompt, enter the following set of
commands:
SH1 (config) # peer <HP EFS WAN Accelerator-2 IP addr> version min 6
SH1 (config) # peer <HP EFS WAN Accelerator-2 IP addr> version max 6
SH1 (config) # peer <HP EFS WAN Accelerator-3 IP addr> version min 6
SH1 (config) # peer <HP EFS WAN Accelerator-3 IP addr> version max 6
SH1 (config) # write memory
SH1 (config) # restart
8. On HP EFS WAN Accelerator-2, at the system prompt, enter the following set of
commands:
SH2 (config) # peer <HP EFS WAN Accelerator-1 IP addr> version min 6
SH2 (config) # peer <HP EFS WAN Accelerator-1 IP addr> version max 6
SH2 (config) # peer <HP EFS WAN Accelerator-3 IP addr> version min 6
SH2 (config) # peer <HP EFS WAN Accelerator-3 IP addr> version max 6
SH2 (config) # write memory
SH2 (config) # restart
9. On HP EFS WAN Accelerator-3, at the system prompt, enter the following set of
commands:
SH3 (config) # peer <HP EFS WAN Accelerator-2 IP addr> version min 6
SH3 (config) # peer <HP EFS WAN Accelerator-2 IP addr> version max 6
