Enabling IPv6 Communication on HyperScale X Appliance

IPv6 can be enabled for the data protection network, once the nodes are deployed. Storage pool network must remain in the IPv4 network.

Procedure

1. Set the MediaAgents associated with the nodes in the Maintenance mode. For more information, see Setting the MediaAgent on Maintenance Mode.

   Note: This will stop all activities in the HyperScale X cluster and as a result jobs will go into the Pending state.

2. Login to a node using the system console. (For example, using KVM, not SSH.)

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

   For example, to configure the IPv6 network interface for enpsf3, create the following file:

   /etc/sysconfig/network-scripts/ifcfg-enpsf3

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

   • Add the follwoing contents to /etc/sysconfig/network-scripts/ifcfg-enpsf3:

     TYPE=Ethernet
     
     BOOTPROTO=none
     
     DEFROUTE=yes
     
     IPV4_FAILURE_FATAL=no
     
     IPV6INIT=yes
     
     IPV6_AUTOCONF=no
     
     IPV6_DEFROUTE=yes
     
     IPV6_FAILURE_FATAL=no
     
     NAME=enpsf3
     
     DEVICE=enpsf3
     
     ONBOOT=yes
     
     DNS1=xxx.x.x.x
     
     DNS2=xxx.x.x.x
     
     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=

   • Add the following contents to /etc/sysconfig/network-scripts/ifcfg-enpsf3 to enable bonding on network interfaces:

     Data protection Network –Public Interface
     
     DEVICE=enpsf3
     
     NAME=enpsf3
     
     TYPE=Ethernet
     
     BOOTPROTO=none
     
     ONBOOT=yes
     
     MASTER=bond0
     
     SLAVE=yes
     
     ----------------------
     
     DEVICE=bond0
     
     NAME=bond0
     
     BONDING_OPTS="mode=active-backup"
     
     TYPE=Bond
     
     BONDING_MASTER=yes
     
     IPV6ADDR=XXXXX
     
     IPV6INIT=yes
     
     IPV6_AUTOCONF=no
     
     IPV6_DEFROUTE=yes
     
     IPV6_FAILURE_FATAL=no
     
     IPV6_PRIVACY=no
     
     ONBOOT=yes
     
     BOOTPROTO=none
     
     Storage Pool network-Private NW
     
     DEVICE=enpsf3
     
     NAME=enpsf3
     
     TYPE=Ethernet
     
     BOOTPROTO=none
     
     ONBOOT=yes
     
     MASTER=bond1
     
     SLAVE=yes
     
     ---------------------
     
     DEVICE=bond1
     
     NAME=bond1
     
     BONDING_OPTS="mode=active-backup"
     
     TYPE=Bond
     
     BONDING_MASTER=yes
     
     IPADDR=XXXXX
     
     PREFIX=24
     
     ONBOOT=yes
     
     BOOTPROTO=none

     Substitute the values for the following parameters with appropriate values:

     NAME=

     DEVICE=

     IPV6ADDR=

     IPADDR=

4. If you have configured the management network during setup, configure the IPv6 network interface for the management network.

   For example, to configure the IPv6 network interface for enpsf1, create the following file:

   /etc/sysconfig/network-scripts/ifcfg-enpsf1

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

   • Add the following contents to /etc/sysconfig/network-scripts/ifcfg-enpsf1:

     TYPE=Ethernet
     
     BOOTPROTO=none
     
     DEFROUTE=yes
     
     IPV4_FAILURE_FATAL=no
     
     IPV6INIT=yes
     
     IPV6_AUTOCONF=no
     
     IPV6_DEFROUTE=yes
     
     IPV6_FAILURE_FATAL=no
     
     NAME=enpsf1
     
     DEVICE=enpsf1
     
     ONBOOT=yes
     
     DNS1=xxx.x.x.x
     
     DNS2=xxx.x.x.x
     
     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=

     Note: Management ports cannot be configured with bonding.

5. Stop the HyperScale cluster on the node. For more information, see Stopping and Starting the Cluster.

6. Restart the node. For more information, see Stopping and Starting a Node.

7. Repeat steps 2 to 6 on the other nodes in the storage pool.

8. Enable IPv6 communication in the CommServe server and the MediaAgents associated with the nodes. For more information, see Enabling CommCell Communication Using IPv6 After Installation.

9. Restart the services on both the CommServe server and the MediaAgent nodes after setting the registry keys. For more information, see Restarting Services on a File Server or a Server.

10. Check network connectivity between the CommServe server and the MediaAgent nodes using the following command:

    ping -6 <IPv6_address>

11. Perform a readiness check to the MediaAgent nodes. For more information, see Checking Readiness.

12. Remove the Maintenance mode from the MediaAgents. For more information, see Setting the MediaAgent on Maintenance Mode.
