Enabling IPv6 Communication on HyperScale 1.5 Appliance

IPv6 protocol can be enabled on HyperScale nodes for data protection and other operations.

Procedure

Configure the IPv6 network interface by creating the /etc/sysconfig/network-scripts/ifcfg-* file.

For example, to configure the IPv6 network interface for eno3, create the following file:

/etc/sysconfig/network-scripts/ifcfg-eno3

For additional information about configuring network interface on IPv6, see https://access.redhat.com/solutions/347693.

Contents of /etc/sysconfig/network-scripts/ifcfg-eno3:

 
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no

ONBOOT=yes
DNS1=127.0.0.1
DNS2=127.0.0.1
IPV6ADDR=xxxxx
IPV6_DEFAULTGW=xxxxx
IPV6_PRIVACY=no

Substitute the values for the following parameters with appropriate values:

NAME=``DEVICE=

DNS1=``DNS2=

IPV6ADDR=``IPV6_DEFAULTGW=

Create necessary entries in the /etc/hosts file with appropriate hostname and IPv6 address on the CommServe and the MediaAgent nodes.
To the CommServe and the MediaAgent nodes, add the nPreferredIPFamily additional setting as shown in the following table.

For instructions about adding an additional setting from the CommCell Console, see Adding or Modifying Additional Settings from the CommCell Console.

Restart the services on both the CommServe and the MediaAgent nodes after setting the registry keys.
- For more information on restarting services on Windows, see Restarting a Service on Windows Clients.
- For more information on restarting services on UNIX, see Commands to Control Services on UNIX Clients.
Check network connectivity between the CommServe and the MediaAgent nodes using the following command:
```
ping -6 IPv6_address
```
Configure the IPv4 network interface for the storage pool network.

For example, to configure the IPv4 network interface for eno4, create the following file:

/etc/sysconfig/network-scripts/ifcfg-eno4
Check network connectivity between the storage pool interfaces using the ping command.
Navigate to the following folder:
```
/opt/commvault/MediaAgent
```
Register the nodes using the following command:
```
./registertocs.py
```
When prompted, provide the following information:
- CommServe name: Type the fully qualified host name for the CommServe computer.
- CommServe user name and password: Type the credentials to access the CommServe.
Once the nodes are successfully registered, perform a readiness check to the MediaAgent nodes from the Commcell Console.

For more information about performing the readiness check, see Viewing the Check Readiness for File System Clients, Database Clients, and Pseudo Client.
After a successful readiness check, if required, create the Storage Pool using the MediaAgent nodes.

For more information about creating a storage pool, see Configuring a Scale-Out Storage Pool.
