Disabling IPv6 Communication on HyperScale X Appliance

rpcbind.socket will not start with IPv6 disabled and as a result storage pool may not be online once the Hyperscale node is rebooted. In such situations disable the IPv6 communication.

Procedure

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

  2. If IPv6 was already enabled as described in Enabling IPv6 Communication on HyperScale Nodes, make sure to revert the changes in the appropriate ifcfg-* files.

  3. Add the following entry in /etc/sysctl.conf file.

    net.ipv6.conf.all.disable_ipv6 = 1
  4. Rebuild the initial ramdisk image ( initrd or initramfs) using the following command to incorporate the changes made to /etc/sysctl.conf into the initramfs.

    dracut -v -f
  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.

    You will see the rpcbind.socket running with IPV6 in disabled state.

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

  8. Disable IPv6 communication in 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 and the MediaAgent nodes after setting the registry keys. For more information, see Restarting Services on a File Server or a Server.

  10. Ping and check network connectivity between the CommServe server and the MediaAgent nodes.

  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.
