Both Ethernet ports for a RAID controller module have been assigned to the same subnet. For typical configurations, you should only use one Ethernet port per RAID controller module. 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 array.
The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.
| 1 |
| If... |
Then... |
| You are using a support service that needs to use the second Ethernet port for a RAID controller module |
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 array
(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 array
(refer to the Network Management Type column in the Enterprise Management Window)
|
Go to step 4. |
|
| 3 |
Blink the RAID controller module 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 RAID controller module so that only one Ethernet cable remains attached to the RAID controller module. |
| b |
Go to step 6. |
|
| 4 |
| If... |
Then... |
| You know which Ethernet port is being used for management of the storage array |
Remove the Ethernet cable from the RAID controller module that is not being used for management purposes. There must be only one Ethernet cable connected per RAID controller module.
When you are finished, go to step 6.
|
| You do NOT know which cable is being used for management of the storage array |
Go to step 5. |
|
| 5 |
| a |
From the left pane of the Enterprise Management Window, hover the mouse pointer over this storage array.
The IP addresses that appear are assigned to the Ethernet port(s) that you are using to manage this storage array (one per RAID controller module).
|
| b |
Record the IP address of the RAID controller module(s). |
| c |
From the Array Management Window, select the affected RAID controller module.
Refer to the Details area for more information.
|
| d |
Select the RAID Controller Module >> 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. |

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. |
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.
