4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

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 process 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 process locates another network that all servers in the cluster can
access, all of the servers fail over the administrative network to that network. The
process looks for another network in this order:
• Networks that allow administrative traffic.
• Networks that discourage administrative traffic.
If Matrix Server must use a network that was configured to discourage administrative
traffic, it will fail over to a network that allows the traffic as soon as that network
becomes available to all servers in the cluster.
