HP StorageWorks Enterprise File Services WAN Accelerator 2.1.5 Command-Line Interface reference manual (June 2006)

118 4 - CONFIGURATION-MODE COMMANDS
peer
Description Configures minimum and maximum protocol version. The no command option
removes the protocol version.
Syntax peer <P addr> version [min <version> | max <version>]
Parameters
Usage Version 2.1.5 of the HP EFS WAN Accelerator supports new intercommunication
protocols as well as the 1.2 intercommunication protocols.
Version 2.1.5 HP EFS WAN Accelerators do not require any configuration changes
because the 2.1.5 appliances understand the protocols used in the 1.2 appliances.
However, as the client-side HP EFS WAN Accelerator, by default 2.1.5 HP EFS WAN
Accelerators 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, 2.1.5 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 2.1.5 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
2.1.5 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 2.1.5 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
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.
<IP addr> Specifies the in-path or out-of-path (or both) HP EFS WAN
Accelerator.
min <version> Specifies the protocol version number: 5 or 6.
max <version> Specifies the protocol version number: 5 or 6.
