Configuring a bond device and assigning an IP address to the bonded device or to a VLAN on the bonded device
For greater resiliency, you can bond the management interfaces eth1 and eth2 and assign an IP address to the bonded device.
Before you configure bonding, ensure that both eth1 and eth2 are physically connected to the switch and the gateway for your network is reachable from eth1 and eth2 network interfaces.
Pick any of the nodes to create a bond and assign an IP to the bonded device so that it is accessible on the network. You can then connect to that node using the assigned IP address and start the NetBackup Flex Scale cluster configuration.
The node to which you assign the IP address and from where you start the cluster configuration is called the driver node.
Note:
Perform these steps on one of the nodes only. You do not have to do this on all the nodes. You require physical access to the system console.
To configure bonding for eth1 and eth2 and assigning a public IP to the bonded device or to a VLAN on bonded device on a node:
- From the system console, log on to one of the nodes using the default admin user account. Enter the following user credentials at the command prompt:
User:
adminPassword:
P@ssw0rd
Note:
The admin user account is used prior to the cluster configuration only. This account is blocked after the cluster is configured successfully.
- Run the set network bond command to assign a public IP address to the bonded interface.
Type set network bond and press Tab to view the next available parameters.
If the network is configured to use VLAN, use the set network bond gateway ip netmask mode bond_vlanid command.
Use the following syntax on the command prompt:
set network bond gateway ip netmask mode xmit or set network bond gateway ip netmask mode bond_vlanid
Parameter
Description
ip
A public IP address that is to be assigned to the node.
netmask
The subnet mask of the network to which the public IP address belongs.
gateway
The IP address of the gateway server in your network.
mode
The mode to be used for bonding.
xmit
The transmission hash policy for the bonding mode. This parameter is optional. If this option is not specified the default policy is used for each bonding mode.
bond_vlanid
The VLAN ID if you configure VLAN on the bonded interface.
Example:
set network bond gateway=10.100.10.1 ip=10.100.10.100 netmask=255.255.0.10 mode=802.3ad xmit=layer3+4
set network bond gateway=10.100.10.1 ip=10.100.10.100 netmask=255.255.0.10 mode=802.3ad xmit=layer3+4 bond_vlanid=999
Note:
Both eth1 and eth2 must be physically connected and the specified gateway in the above command should be reachable from both the interfaces eth1 and eth2. If any of the devices is not connected or can't reach the gateway from that device, the set network bond command fails.
Press Enter.
The system starts making the required network changes based on the provided inputs. Messages similar to the following appear on the command prompt:
INFO: Validating Inputs INFO: Setting the IP/Netmask INFO: Persisting the changes INFO: Applying the changes
- Ensure that the following confirmation message is displayed on the command prompt:
SUCCESS: Device configured successfully!When you see this message, it indicates that the IP has been assigned to the node successfully.
You can now log out of the node.
- Verify that the node is reachable and that you can access the node using the assigned IP address.
You can now proceed to the cluster configuration workflow.
