Symptoms

Sun Storage Common Array Manager (CAM) reports an open alarm against a Sun Storage 2500-M2 or 6000 array for a NET_SETUP_ERROR. In this example, the alarm is opened on a Sun Storage 6780.

Event Code         : 80.66.1077
Event Type         : 6780.ProblemEvent.REC_NET_SETUP_ERROR
Severity           : 0
Sample Description : Network setup error detected on controller {0}.
Probable Cause     : Both of the ethernet ports on a single controller have been
                     configured to use the same subnet.
Recommended Action : Change the ethernet configuration so that the ports on a
                     single controller are on different subnets

Cause

As indicated by the alarm, both Ethernet ports on a single RAID controller have been configured on the same subnet. You can view this in two places:

CAM > Storage Array > Physical Devices > Controllers > Controller A(B) > Ethernet Port 1 and Ethernet Port 2.
The storageArrayProfile.txt file of the supportdata. For example:

Ethernet port: 1
MAC address: 00:a0:b8:xx:xx:xx
Network configuration: Static
IP address: 135.xx.xx.xx
Subnet mask: 255.255.252.0
Gateway: 135.xx.xx.xx

Ethernet port: 2
MAC address: 00:a0:b8:xx:xx:xx
Network configuration: Static
IP address: 135.xx.xx.xx
Subnet mask: 255.255.252.0
Gateway: 135.xx.xx.xx

Solution

Do not use Ethernet Port 2. When managing the array with CAM, you must only use Ethernet Port 1 for OOB communication. Ethernet Port 2 must be unconfigured in CAM, and unplugged from any switch. While the error message suggests that subnets are involved, in fact Ethernet Port 2 should never be configured or connected.

CAM > Storage Array > Physical Devices > Controllers > Controller A(B) > Ethernet Port 1 and Ethernet Port 2.

Ethernet port 2 is reserved for onsite diagnostics and Field Engineers to connect using Field Tools.
