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:

Entity

IP Address

Bonded public (data protection network) IP address

 

Data protection Netmask

 

Data Protection Gateway

 

Data Protection DNS Servers

 

Procedure

  1. Login to the node using the following default credentials:

    Login: root

    Password: cvadmin

    Note: This password can be changed during setup.

  2. Navigate to the following folder:

    /opt/commvault/MediaAgent

  3. Execute the cvnwlacpbond.py with appropriate parameters to setup the bonding.
  4. Restart the network service to create the bonding with the appropriate parameters using the following command:

    systemctl restart network

  5. Repeat these steps in the other nodes.

Examples

Help to Run the Bonding modes

Use the following command to display help:

./cvnwlacpbond.py -h

The following output will be displayed:

usage: cvnwlacpbond.py [-h] [-c] [-m {802.3ad,active-backup}] [-t {dp,sp}]
[-i IP] [-f IFACE IFACE] [-n NETMASK] [-g GATEWAY]
[-d DNS [DNS ...]] [-s]

Tool to augment and validate network settings for HyperScale

optional arguments:
-h, --help show this help message and exit

Configure Network:
-c, --configure Option to configure network
-m {802.3ad,active-backup}, --mode {802.3ad,active-backup}
Mode of bonding. Defaults to 802.3ad
-t {dp,sp}, --nwtype {dp,sp}
Type of network. Defaults to Data Protection
-i IP, --ip IP IP address of the interface
-f IFACE IFACE, --iface IFACE IFACE
Interfaces to use for configuring the bond
-n NETMASK, --netmask NETMASK
Netmask IP of the interface
-g GATEWAY, --gateway GATEWAY
Gateway IP for the interface to connect to
-d DNS [DNS ...], --dns DNS [DNS ...]
DNS IPs for the interface to configure with
-s, --suppress Suppress link validation while configuring the
interface

Note: Multiple DNS servers can be provided for the -d option, using space as the delimiter.

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

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'}
