IDPA: Avamar Services with red exclamation "Avamar Services is/are down/disabled"

In ACM, Avamar Services are red with the exclamation: "Avamar Services [] is/are down/disabled"
 

ACM is not able to properly communicate with the NDMP component.

From ACM server.log, ACM is attempting to run 'dpnctl status' to the Avamar NDMP. It is failing with [bash: dpnctl: command not found]:

Confirm this is the NDMP IP from the /usr/local/dataprotection/var/configmgr/server_data/config/ndmpconfig.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<NDMPConfig>
<uneditable>false</uneditable>
<NDMPList>
<NDMPIpField>
<ndmpIp>10.10.10.32</ndmpIp>
<ndmpIpFlag>true</ndmpIpFlag>
</NDMPIpField>
</NDMPList>
</NDMPConfig>

1. Rename ndmpconfig.xml file:

mv /usr/local/dataprotection/var/configmgr/server_data/config/ndmpconfig.xml /usr/local/dataprotection/var/configmgr/server_data/config/x-ndmpconfig.xml

2. Edit file /usr/local/dataprotection/var/configmgr/server_data/skuconfig/selskuconfig.xml and set NDMPCount 0 in tag "<Count>0</Count>" under <NDMP>

....
    </AVEVM>
</AvamarServer>
    <NDMP>
        <Physical>true</Physical>
        <Count>0</Count>
        <AvamarClientRPMName>AvamarClient-linux-rhel4-x86_64-7.3.101-125.rpm</AvamarClientRPMName>
        <AvamarNDMPRPMName>AvamarNDMP-linux-rhel4-x86_64-7.3.101-125.rpm</AvamarNDMPRPMName>
    </NDMP>
</Avamar>
....

3. Restart webapp service:

service dataprotection_webapp restart

ACM should now report as intended:
 

Should any services show otherwise, investigate accordingly.
