Avamar: How to Change Hostname and IP Address on NDMP Accelerator Node

How to change the Hostname or IP address of an Avamar NDMP Node:

Preparation:

Log in to the NDMP Accelerator node using RMM/iDRAC.

Procedure:

1. Stop the Avamar client services:

service avagent stop

2, Update the /etc/hosts file with the new hostname and IP address.

vi /etc/hosts

3. Update the Domain Name System (DNS) server entries in /etc/resolv.conf:

vi /etc/resolv.conf

4. Set the new hostname in /etc/HOSTNAME:

vi /etc/HOSTNAME

5. Modify the network interface configuration (eth0 or bond0) with the new IP settings.

vi /etc/sysconfig/network/ifcfg-eth0

-- Or --

vi /etc/sysconfig/network/ifcfg-bond0

6. If required, change the default gateway:

vi /etc/sysconfig/network/routes

7. Restart the NDMP Accelerator node per Avamar: How to shut down and restart an Avamar NDMP accelerator node

8. Verify SSH connectivity using the new IP address.

9. Update RMM/iDRAC settings if the IP or hostname changed.

10. Modify DNS records for the node and verify both forward and reverse lookups.

Example checks:

nslookup 
nslookup 
ping 
ping

11. Update the Utility/Single node with the new accelerator address:

nodedb update if --addr= --new-addr=

12. Identify NDMP clients on the accelerator node:

service avagent status
mccli client show --domain=/ --recursive

13. Deactivate each identified NDMP client on the Avamar Server:

mccli client edit --domain= --name= --activated=false

14. Re‑register the NDMP clients from the accelerator node:

avregister

15. Perform a backup and restore test to confirm functionality.
