The Member Network window appears (Figure: Member Network).

Figure: Member Network

The Status of Network Interfaces panel shows the following information:

Operational status – This is the current status of the network interface and can be:
up – Operational, connected to a functioning network, configured with an IP address and subnet mask, and enabled.
down – Not operational, not connected to a functioning network, not configured with an IP address or subnet mask, or disabled.
Requested status – This status is set by administrative action:
enabled – Configured and serving I/O.
disabled – Not serving I/O. Might be configured.

If the operational status is down, but the requested status is enabled, identify and correct the error.

To protect against network interface or port failure, connect multiple network interfaces on both control modules to the network.

Speed – Make sure that the interface speed is adequate.
MTU size – The path MTU size depends on the iSCSI initiator setting.
Packet errors – A few packet errors are not usually a problem. If a large number of packet errors occur, network problem or a network interface or port failure may exist. Identify and correct the problem.

The IP Configuration panel shows each interface and its IP address, netmask, MAC address and description, if any.
