Change the IP address for a HyperScale Edge node

You can change the IP addresses for the public (Data Protection) network on a HyperScale Edge node.

Use this procedure to address network changes that require an IP address change.

Prerequisites

• Update the DNS to reflect the new IP address of the Data Protection network.

• Set the Disk libraries and MediaAgents associated with the nodes to maintenance mode.

  • To set the MediaAgents to maintenance mode, see Setting the MediaAgent on Maintenance Mode.

  • To mark the library offline, see Editing Disk Library Properties.

To change the IP address for the public (Data Protection) network on a HyperScale Edge node, follow these steps:

1. Update the relevant network configuration file for the public network interface with the new IP address - bonded and non-bonded as follows:

   1. Navigate to /etc/sysconfig/network-scripts.

   2. Open the following file for editing:

      ifcfg-<interface name>n

2. Remove the immutable attribute from resolv.conf file:

   chattr -i /etc/resolv.conf

3. Modify the file with nano, vi, or any other editing tool.

4. After you finish editing, reset the file attribute to read-only to prevent accidental changes:

   chattr +i /etc/resolv.conf

5. Restart the network service:

   systemctl restart network

What to Do Next

• Remove maintenance mode from the disk libraries and MediaAgents. For more information, see the following pages:

  • Setting the MediaAgent on Maintenance Mode

  • Editing Disk Library Properties

• Run the Check Readiness Report to verify that the HyperScale Edge node is available. For more information, see Running a Readiness Check.
