1. Install a secondary control module in the member.
2. For each configured network interface, connect the Ethernet port on th
e secondary control module to the
network.
Configuring redundant network switches
Redundant network switches protect against network and switch failures and improve network performance.
Requirement: Requ
ires redundant network connections. See Configuring redundant network connections.
1. Distribute redundant network connections across multiple switches.
2.
Connect switches to links with sufficient inter
-switch bandwidth.
Displaying the member network configuration
1. Click Group, then expand Members, then select the member name, and then click the Network tab.
2. In the Member Network window, review the current n
etwork configuration for the member.
Configuring network interfaces
When you add a member to a group, you configure only one network interface. It is best practice to configure all
network interfaces eligible for iSCSI traffic. The number of iSCSI eligible interfaces depends on the type of control
module.
You can also change the existing member network configuration or enable or
disable an interface. If you change the
IP address for a functioning network interface, the member disconnects all iSCSI initiators from that interface.
Most initiators reconnect automatically.
IPv6 Note: If you are using IPv6 a
ddresses exclusively in the group, you must use the CLI to configure a network
interface. See the CLI Reference manual.
1. Connect the network interface on the active control module
to the network.
Recommendation: De
ll recommends that you also connect the network interface on the secondary control
module to increase availability.
2. Obtain the IP address and netmask for the inte
rface. At least one network interface on a member must be on the
same subnet as the group IP address.
3. Click
Group, then expand Members, then select the member name, and then click the Network tab.
4. In the IP Configuration panel, select a network interface and
click Modify IP settings.
5. Enter the following information in the Modify IP Settings dialog box:
•
IP address for the network interface.
• Subnet mask (netmask) for the network interface IP address.
