HP StorageWorks Enterprise File Services WAN Accelerator 2.1.11 release notes (392363-007, January 2007)

• CIFS performance degradation occurs with multiple sets (pairs) of in-path HP EFS WAN Accelerators

(Bug #3746).

For example:

client->DL320-2010->WAN->DL320-2010->DL320-1010->DL320-2010->server

This problem is dependent on this configuration. Contact HP Technical Support for further information at

Upgrading from version 1.2.6 to version 2.1.11

Version 2.1.11 interoperates with version 1.2.6. These instructions assume you are familiar with the HP EFS

WAN Accelerator, the HP EFS WAN Accelerator Command-Line Interface, and the HP EFS WAN

Accelerator Management Console.

IMPORTANT: Do not clear the data store before performing a software upgrade.

NOTE: The following upgrade instructions assume that you have a network of 10 WAN Accelerators

(WAN Accelerator-1 through WAN Accelerator-10). Initially, you will upgrade 3 WAN Accelerators (WAN

Accelerator-1 through WAN Accelerator-3).

Steps for upgrading from version 1.2.6 to version 2.1.11:

1. Connect to the Management Console on each HP EFS WAN Accelerator.

2. Install the version 2.1.11 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 WAN Accelerator page).

5. Connect to the CLI on each of the three HP EFS WAN Accelerators.

6. At the system prompt, enter the following 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

NOTE: This set of commands ensures that HP EFS WAN Accelerators with version 2.1 can communicate

with all HP EFS WAN Accelerators with version 1.2.6 in the network. To take advantage of the version 2.1

features, configure the HP EFS WAN Accelerator with version 2.1 to communicate with other HP EFS WAN

Accelerators using the version 2.1 protocol.

7. On WAN Accelerator-1, at the system prompt, enter the following commands:

SH1 (config) # peer <WAN Accelerator-2 IP addr> version min 6

SH1 (config) # peer <WAN Accelerator-2 IP addr> version max 6

SH1 (config) # peer <WAN Accelerator-3 IP addr> version min 6

SH1 (config) # peer <WAN Accelerator-3 IP addr> version max 6

SH1 (config) # write memory

SH1 (config) # restart

8. On WAN Accelerator-2, at the system prompt, enter the following commands:

SH2 (config) # peer <WAN Accelerator-1 IP addr> version min 6

SH2 (config) # peer <WAN Accelerator-1 IP addr> version max 6
