Disabling IPv6 Communication on Commvault HyperScale 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.

Before You Begin

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

Procedure

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

    net.ipv6.conf.all.disable_ipv6 = 1

  2. 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

  3. Edit the /etc/hosts file and remove lines containing ::1.
  4. Reboot the node.

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

  5. Repeat these steps on the other nodes in the storage pool.
