When xCAT installs rhel6 on a physical machine with multiple NICs, You need to manually select the NIC. xcatrhel6
Problem description

Today, rhel5 is successfully installed on a dual-nic physical machine. However, when installing rhel6, you cannot automatically select the NIC for installation. A window will pop up asking you to choose whether to use em1 or em2.

Cause

The reason is that I used the statement similar to the following when adding nodes. At this time, the installation script on rhel6 will choose to use eth0 for installation, however, because our two NICs are identified as em1 and em2 at this time, the eth0 cannot be found, resulting in installation failure. Therefore, we need to manually select the NIC.

Nodeadd <node> mac. interface = eth0 mac. mac =... noderes. installnic = eth0 noderes. primarynic = eth0...

Solution

Change noderes. installnic and noderes. primarynic to use mac, similar to the following statement:

Nodeadd <node> mac. interface = eth0 mac. mac =... noderes. installnic = mac noderes. primarynic = mac...

Corresponding to the preceding statement, xCAT adds a record to both the mac table and noderes. In this case, noderes. installnic and noderes. primarynic is defined as mac, which means that the NIC defined in the mac table can be installed automatically.

This modification is applicable to both rhel5 and rhel6.
