Ethernet Configuration Conflict

What Caused the Problem?

Both Ethernet ports for a controller have been assigned to the same subnet. For typical configurations, you should only use one Ethernet port per controller. The second Ethernet port is reserved for support use and must be on a separate subnet than the Ethernet port that is being used to manage the storage subsystem.

The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

 Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touch components without using a proper ground may damage equipment.

Recovery Steps

1
If... Then...
You are using a support service that needs to use the second Ethernet port for a controller Contact your technical support representative to assist you with correcting this problem.
You are not using a support service Go to step 2.
2
If... Then...
You are using In-Band management of the storage subsystem

(refer to the Network Management Type column in the Enterprise Management Window)

Go to step 3.
You are using Out-of-Band management of the storage subsystem

(refer to the Network Management Type column in the Enterprise Management Window)

Go to step 4.
3 Locate the controller that reported the problem. Refer to the Details area for more information.
a Remove one of the Ethernet cables from either Ethernet port on the controller so that only one Ethernet cable remains attached to the controller.
b Go to step 6.
4
If... Then...
You know which Ethernet port is being used for management of the storage subsystem Remove the Ethernet cable from the controller that is not being used for management purposes. There must be only one Ethernet cable connected per controller.

When you are finished, go to step 6.

You do NOT know which cable is being used for management of the storage subsystem Go to step 5.
5
a From the left pane of the Enterprise Management Window, hover the mouse pointer over this storage subsystem.

The IP addresses that appear are assigned to the Ethernet port(s) that you are using to manage this storage subsystem (one per controller).

b Record the IP address of the controller(s).
c From the Subsystem Management Window, select the affected controller.

Refer to the Details area for more information.

d Select the Controller >> Properties menu option, then select the Network tab.
e Find the Ethernet Port where the IP address does not match any IP address that you recorded in step b.
f Remove the Ethernet cable attached to this port, then go to step 6.
6 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.
