4. Power on the server.
a. Check the MAC address of the new NIC. Use the ifdown eth(n) command, and then
use the ip addr command.
b. Change the HWADDR= line in the relevant ifcfg-eth(n) file to be the MAC address from
the previous step.
c. Follow this procedure for every NIC that was affected by the physical board swapout (for
example, if this was a dual NIC, then two files need to be updated).
d. Restart the network subsystem with service network restart.
e. Run the following command to verify that all is correct
cat /proc/net/bonding/bond(n)
5. For a file serving node, fail back the server using the GUI or CLI:
• On the GUI, select Servers from the Navigator pane, and then select the appropriate server
from the Servers pane. Next, select the server name in the left pane, and click Failback.
• On the CLI, execute the following command:
ibrix_server -f –U –h <server_name>
Replacing a NIC adapter
To replace a NIC adapter on a file serving node or the X9300 Management Server:
1. If the server is an X9300 Management Server, skip this step. If the server is a file serving node,
fail over the server to its standby server using the management console GUI or CLI:
• On the GUI, select Servers from the Navigator pane, and then select the appropriate server
from the Servers pane. Next, select the server name in the lower-left pane, and click Failover.
• On the CLI, execute the following command, where server_name is the server containing
the NIC adapter:
ibrix_server -f -h <server_name>
2. Power down the server.
3. Replace the NIC adapter.
• For a file serving node, see the HP Proliant DL380 G6 Serve r Maintenance and Service Guide.
• For an X9300 Management Server, see the HP Proliant DL360 G6 Server Maintenance and
Service Guide.
4. Power on the server:
a. Check the MAC address of the new NIC. Use the ifdown eth(n) command, then use the
ip addr command.
b. Change the HWADDR= line in the relevant ifcfg-eth(n) file to the MAC address from the
previous step.
c. Repeat steps 4a and 4b for every NIC that was affected by the physical board swap out
(for example, if this was a dual NIC, then two files need to be updated).
d. Restart the network susbsystem with service network restart.
e. Verify that all is correct with cat /proc/net/bonding/bond(n).
