Configuring Network Bonding For Storage Pool Network

Network bonding can be configured for Storage Pool network, when DHCP is not available or enabled.

Before You Begin

Obtain the following IP addresses before you start:

Entity

IP Address

IP address for the bonded interface

Netmask IP for the interface

Gateway IP for the interface to connect to

IP addresses associated with the bonded ports for storage pool network

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. 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 ...]] [-v VLANID] [-nr] [-s] [-r]
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
  -v VLANID, --vlanid VLANID
                        Tagged VLAN ID in case where IP needs to be assigned
                        to tagged VLAN
  -nr, --nonroutable    Data Protection network on a flat network. This will
                        not mandate a gateway to be provided
  -s, --suppress        Suppress link validation while configuring the
                        interface
Restore network files:
  -r, --restore         Restore network files from the initial boot time

Note

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

Configuring Active-Backup Bonding on Storage Pool Network

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

 
./cvnwlacpbond.py -c -m active-backup -t sp -i Bonded IP for private storage pool network -n Storage Pool Netmask IP

For example:

./cvnwlacpbond.py -c -m active-backup -t sp -i 10.11.11.71 -n 255.255.255.0

The following output will be displayed:

Arguments entered: {'nwtype': 'sp', 'configure': True, 'ip': '10.11.11.71', 'netmask': '255.255.255.0', 'mode': 'active-backup', 'dns': None, 'validate': False, 'gateway': None}

Configuring LACP Bonding on Storage Pool Network

Use the following options to set mode 4 (LACP bonding) for Storage Pool network:

 
./cvnwlacpbond.py -c -m 802.3ad -t sp -i Bonded IP for private storage pool network -n Storage Pool Netmask IP

For example:

./cvnwlacpbond.py -c -m 802.3ad -t sp -i 10.11.11.51 -n 255.255.255.0

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

 
./cvnwlacpbond.py -c -m 802.3ad -t sp -i Bonded IP for private storage pool network -f enpsf1 enpsf6 -n Storage Pool Netmask IP

For example:

./cvnwlacpbond.py -c -m 802.3ad -t sp -i 10.11.11.51 -f enpsf1 enpsf6 -n 255.255.255.0

The following output will be displayed:

Arguments entered: {'nwtype': 'sp', 'configure': True, 'ip': '10.11.11.51', 'netmask': '255.255.255.0', 'mode': '802.3ad', 'dns': None, 'validate': False, 'gateway': None}
