HP StorageWorks Enterprise File Services WAN Accelerator 2.1.7 Command-Line Interface Reference Manual (392361-004, June 2006)

122 4 - CONFIGURATION-MODE COMMANDS
Version 2.1 HP EFS WAN Accelerators do not require any configuration changes
because the 2.1 appliances understand the protocols used in the 1.2 appliances.
However, as the client-side HP EFS WAN Accelerator, by default 2.1 HP EFS WAN
Accelerator will initiate connections with the server-side HP EFS WAN Accelerator
using the new version 6 service protocol. This disrupts connectivity with any 1.2
server-side HP EFS WAN Accelerator peers. To remedy this situation, 2.1 HP EFS
WAN Accelerators allow you to configure the version of the service protocol using the
IP address for each peer when initiating HP EFS WAN Accelerator to HP EFS WAN
Accelerator connections. To configure the protocol version, the following CLI
commands must be issued for each 1.2 HP EFS WAN Accelerator peer in the network:
sh> peer <addr> version min 5
sh> peer <addr> version max 5
These CLI commands instruct the 2.1 HP EFS WAN Accelerator to use only the
version 5 protocols when initiating service connections.
After all the 1.2 HP EFS WAN Accelerators in the network have been upgraded to 2.0
or 2.1 HP EFS WAN Accelerators, the version commands can be removed:
sh> no peer <addr> version min
sh> no peer <addr> version max
Because it might be difficult to maintain an up-to-date list of 1.2 HP EFS WAN
Accelerators in the network, an effective strategy is to configure all 2.1 HP EFS WAN
Accelerators to use version 5 protocol by default with all peers. This can be done by
specifying 0.0.0.0 as the peer address:
sh> peer 0.0.0.0 version min 5
sh> peer 0.0.0.0 version max 5
In all cases, specifying version 5 for the service connection protocol prevent the ability
to enable the new 2.0 optimization policy feature as that requires the version 6 sport
connection protocol.
Example
minna (config) # peer 10.0.0.1 version min 5
minna (config) #peer 10.0.0.2 version max 5
pfs auto-launch enable
Description Enables the Proxy File Service (PFS) process to start automatically. If PFS is set to
manual (the default setting), you must start PFS manually using the pfs start
command.
For detailed information about PFS, see the HP StorageWorks Enterprise File Services
WAN Accelerator Deployment Guide.
NOTE: PFS is not supported on the Model 500, 510. These models do not have the necessary
disk capacity to perform PFS. PFS supports only Windows 2000 and above domains
