Network interfaces and the Management Console When HP Scalable NAS is started, the ClusterPulse daemon probes the servers in the cluster to locate network interfaces and then adds the interfaces to its configuration file. The Servers window on the Management Console shows the network interfaces for each server as defined in this file. (Because there can be stale information in the configuration file, the Servers window may not match your current network configuration exactly.) Each network interface is labeled "Hosting Enabled" or "Hosting Disabled," which indicates whether it can be used for virtual hosts. The Management Console uses the following icons to specify whether the network interface allows or discourages administrative traffic. The network interface allows administrative traffic. A green checkmark indicates the current administrative network. A red X indicates that the interface is down. The network interface discourages administrative traffic. The network interface excludes administrative traffic. Administrative network failover An administrative network failure occurs when the interface on a particular server is no longer receiving cluster administrative traffic. Some possible causes of the failure are a bad cable or network interface card (NIC). When the administrative network fails on a server, the PanPulse daemon on that server attempts to select another network to act as the administrative network. A message regarding the network failure also appears in the event log. When the PanPulse daemon locates another network that all servers in the cluster can access, all of the servers fail over the administrative network to that network. The daemon looks for another network in this order: • Networks that allow administrative traffic. • Networks that discourage administrative traffic.

Network interfaces and the Management Console
When HP Scalable NAS is started, the ClusterPulse daemon probes the servers in
the cluster to locate network interfaces and then adds the interfaces to its configuration
file. The Servers window on the Management Console shows the network interfaces
for each server as defined in this file. (Because there can be stale information in the
configuration file, the Servers window may not match your current network
configuration exactly.)
Each network interface is labeled
Hosting Enabled
or
Hosting Disabled,
which
indicates whether it can be used for virtual hosts.
The Management Console uses the following icons to specify whether the network
interface allows or discourages administrative traffic.
The network interface allows administrative traffic. A green checkmark
indicates the current administrative network. A red X indicates that the interface
is down.
The network interface discourages administrative traffic.
The network interface excludes administrative traffic.
Administrative network failover
An administrative network failure occurs when the interface on a particular server is
no longer receiving cluster administrative traffic. Some possible causes of the failure
are a bad cable or network interface card (NIC).
When the administrative network fails on a server, the PanPulse daemon on that
server attempts to select another network to act as the administrative network. A
message regarding the network failure also appears in the event log.
When the PanPulse daemon locates another network that all servers in the cluster
can access, all of the servers fail over the administrative network to that network. The
daemon looks for another network in this order:
Networks that allow administrative traffic.
Networks that discourage administrative traffic.
