Configuring Network Bonding For Data Protection Network

Configure the network bonding for the Data Protection network.

Before You Begin

Obtain the following IP addresses before you start:

Procedure

1. Power on the nodes.

   Note

   Recommended: Power on 3 un-configured nodes at a time. (If you have more than 3 un-configured nodes, you can add the other nodes later.)

   

   Tip

   • If the login prompt is not displayed, press <Alt> + <F2> or <++> keys to display the prompt.

   • Note down the serial number (Hostname) for the node. This will be useful to identify the node during setup.

2. Login to a node using the following default credentials:

   Login: root

   Password: cvadmin

   Note

   This password can be changed during setup.

3. Navigate to the following folder:

   /opt/commvault/MediaAgent

4. Execute the cvnwlacpbond.py with appropriate parameters to setup the bonding.

5. Restart the network service to create the bonding with the appropriate parameters using the following command:

   systemctl restart network

6. Repeat these steps in the other nodes.

Examples

Configuring Active-Backup Bonding on Data Protection Network

Use the following options to set mode 1 (active-backup bonding) for Data Protection network:

 
./cvnwlacpbond.py -c -m active-backup -t dp -i <Bonded IP for public data protection network> -n < Data Protection Netmask IP> -g <Data Protection Gateway IP> -d <Data Protection DNS Server IP1> <Data Protection DNS Server IP2>

For example:

./cvnwlacpbond.py -c -m active-backup -t dp -i 10.11.11.61 -n 255.255.255.0 -g 10.11.11.1 -d 10.11.11.21 10.11.11.22

The following output will be displayed:

Arguments entered: {'nwtype': 'dp', 'configure': True, 'ip': '10.11.11.61', 'netmask': '255.255.255.0', 'mode': 'active-backup', 'dns': ['10.11.11.21', '10.11.11.22'], 'validate': False, 'gateway': '10.11.11.1'}

Configuring LACP Bonding on Data Protection Network

Use the following options to set mode 4 (LACP bonding) for Data Protection network:

 
./cvnwlacpbond.py -c -m 802.3ad -t dp -i <Bonded IP for public data protection network> -n < Data Protection Netmask IP> -g <Data Protection Gateway IP> -d <Data Protection DNS Server IP1> <Data Protection DNS Server IP2>

For example:

./cvnwlacpbond.py -c -m 802.3ad -t dp -i 10.11.11.50 -n 255.255.255.0 -g 10.11.11.1 -d 10.11.11.11 10.11.11.12

Use the following options to set mode 4 (LACP bonding) for Data Protection network using specific interfaces:

 
./cvnwlacpbond.py -c -m 802.3ad -t dp -i <Bonded IP for public data protection network> -f enpsf2 enpsf3 -n < Data Protection Netmask IP> -g <Data Protection Gateway IP> -d <Data Protection DNS Server IP1> <Data Protection DNS Server IP2>

For example:

./cvnwlacpbond.py -c -m 802.3ad -t dp -i 10.11.11.50 -f enpsf2 enpsf3 -n 255.255.255.0 -g 10.11.11.1 -d 10.11.11.11 10.11.11.12

The following output will be displayed:

Arguments entered: {'nwtype': 'dp', 'configure': True, 'ip': '10.11.11.50', 'netmask': '255.255.255.0', 'mode': '802.3ad', 'dns': ['10.11.11.11', '10.11.11.12'], 'validate': False, 'gateway': '10.11.11.1'}

Help to Run the Bonding modes

Use the following command to display help:

./cvnwlacpbond.py -h

The following output will be displayed:
