Configuring the Service Processor network

After you expand a cluster, you must configure the Service Processor (SP) network on the new nodes. If the SP uses manual network configuration, you must configure the IP addresses for the SP on the new nodes. If the SP uses automatic network configuration, you must identify the IP addresses that were selected.

Steps

  1. If the cluster SP uses manual network configuration, configure IP addresses on both nodes for the SP network by using the system service-processor network modify command.
    Example
    The following commands configure the SP network in cluster1-3 and cluster1-4 nodes:
    cluster1::> system service-processor network modify -node cluster1-3 -address-family IPv4 -enable true -ip-address 192.168.123.98-netmask 255.255.255.0 -gateway 192.168.123.1
    cluster1::> system service-processor network modify -node cluster1-4 -address-family IPv4 -enable true -ip-address 192.168.123.99 -netmask 255.255.255.0 -gateway 192.168.123.1
  2. Verify that the SP network is configured correctly on both the new nodes by using the system service-processor network show command for each node.
    The status should be succeeded. Verification is required in all situations. Even if the SP network was automatically configured, you should verify that it was configured successfully, and you must determine which IP addresses were assigned.
    Example
    The following output indicates that both the cluster1-3 and the cluster1-4 nodes have successful SP network setup:
    cluster1::> system service-processor network show -node cluster1-3
                                 Address

  3. If your site typically has DNS entries for the SP network, verify that the DNS entries are created for the new nodes.
