16.8 Perform the Post-Configuration Steps

After creating a partition on the InfiniBand switch, you must create a child interface for the IPoIB interface on your Exalogic compute node.

For example, on the InfiniBand switch, if you defined a partition with pkey 0x33, with IPoIB enabled, you must complete the following steps on a compute node with port 1 that is either full or limited member of that partition:

Note:

Even though the example uses port 1, you can create child interfaces for both ib0 and ib1 and bond them together on the partitioned network.

1. Log in as a root user.
2. Run the following commands on the command line:

   # cd /sys/class/net/ib0

   echo 0x8033 > create_child

3. Run the following command to verify that the child interface was created:

   # ifconfig ib0.8033

4. Specify your setup for the child interface in an ibcfg-ib0.8033 file in the /etc/sysconfig/networks-scripts directory. Note that it is .8033 even if it might be limited member.
