4.11.4 Set the DNS Server Address on an InfiniBand Network Fabric Switch

You can set or change the DNS server address on an InfiniBand Network Fabric switch.

You can choose to change the DNS server address by using the ILOM Web interface or the ILOM command-line interface on each InfiniBand Network Fabric switch.

• To change the DNS server address using the ILOM Web interface:

  1. Log in as the switch administrator (root) to the ILOM Web interface at http://switch_hostname_or_IP_address.

  2. In the navigation pane on the left side of the window, expand ILOM Administration, then click on Connectivity.

  3. Select the DNS tab.

  4. In the DNS Name Server text box, enter the IP addresses for up to 3 DNS servers. Separate each IP address using a comma character.

  5. Click Save.

• To change the DNS server address using the ILOM command-line interface:

  1. Start the ILOM command-line interface.

     You can access the ILOM command-line interface using various methods, including any of the following:

     • Connect to the InfiniBand Network Fabric switch using SSH as the ilom-admin user.

       $ ssh -l ilom-admin switch_hostname_or_IP_address

     • Connect to the InfiniBand Network Fabric switch using SSH as the switch administrator (root) and then run the ILOM service processor shell (spsh).

       $ ssh -l root switch_hostname_or_IP_address
       # spsh

  2. Using the ILOM command-line interface, run the following command:

     -> set /SP/clients/dns nameserver=dns_ip

     In the command, dns_ip specifies the IP addresses for up to 3 DNS servers in priority order, with each IP address separated by a comma character.

     For example:

     -> set /SP/clients/dns nameserver=192.0.2.100,192.0.2.110,192.0.2.120

  3. Verify the change by examining the output from the following command:

     -> show /SP/clients/dns
