ERROR: no database type or no node resource database could be found with search list /usr/local/avamar/var/probe.xml, stopped at /usr/local/avamar/bin/../lib/dpnutils/node_util.pm line 756.

The probe.xml file is not present:

ls -al /usr/local/avamar/var/probe.xml

ls: cannot access '/usr/local/avamar/var/probe.xml': No such file or directory 

ls -al /usr/local/avamar/var/*probe.xml*

1. Log in to the Avamar Utility Node as admin and load the keys per Avamar: How to Log in to an Avamar Server and Load Various Keys.

2. Generate a new probe.xml file by running the following command:

avmaint networkconfig --ava > /usr/local/avamar/var/new_probe.xml_`date -I` 

3. Verify that the file exists:

ls -al /usr/local/avamar/var/new_probe.xml_`date -I`

ls -al /usr/local/avamar/var/new_probe.xml_`date -I`
-rw------- 1 admin admin 526 Jan 23 20:21 /usr/local/avamar/var/new_probe.xml_2025-01-23

4. Copy the file as original probe.xml file:

cp -v /usr/local/avamar/var/new_probe.xml_`date -I` /usr/local/avamar/var/probe.xml

'/usr/local/avamar/var/new_probe.xml_2025-01-23' -> '/usr/local/avamar/var/probe.xml'

5. Verify that the file has the correct permissions and ownership:

ls -al /usr/local/avamar/var/probe.xml

-rw-r--r-- 1 admin admin 1050 Jan 13 13:18 probe.xml

If the file ownership is incorrect, run the following command:

chown admin:admin /usr/local/avamar/var/probe.xml

If the file permissions are incorrect, run the following command:

chmod 644 /usr/local/avamar/var/probe.xml
