For detailed information about bypass card status lights, see the HP StorageWorks
Enterprise File Services WAN Accelerator Bypass NIC Installation Guide.
If there is a serious problem with the HP EFS WAN Accelerator or it is not powered on, it goes into bypass mode to prevent a single point of failure. If the HP EFS WAN Accelerator is in bypass mode, you are notified in the following ways:
The Intercept/Bypass status light is active. For detailed information about the status lights for each of the bypass cards, see the HP StorageWorks Enterprise File Services WAN Accelerator Bypass NIC Installation Guide.
Critical is displayed in the status bar of the Management Console.
Simple Network Management Protocol (SNMP) traps are sent (if you have set this option).
The event is logged to system logs (syslog) (if you have set this option).
Email notifications are sent (if you have set this option).
In an HP EFS WAN Accelerator
When the fault is corrected, new connections that are made receive optimization: however, connections made during the fault are not. To force all connections to be optimized, enable the kickoff feature. Generally, connections are short lived and kickoff is not necessary. For detailed information about enabling the kickoff feature, see the HP Enterprise File Services WAN Accelerator Management Console User Guide.
TIP: You can close old connections in the Reports: Current Connections page of the
Management Console. For detailed information, see the HP Enterprise File Services WAN
Accelerator Management Console User Guide.
In an
Failover Mode
You can deploy redundant HP EFS WAN Accelerators in your network to ensure optimization continues if there is a failure in one of the HP EFS WAN Accelerators. If the HP EFS WAN Accelerator is in failover mode:
