Below are the server.log which shows the errors after the deployment fails at 71%

Issue is with the SNMP communities while integrating DD with the DPA
 
The SNMP communities gets registered during DD deployment which throws the errors.

For example when we run 

sysadmin@cgfnstpr2-ps1# snmp show rw-communities

Read-write Communities:
Community   Hosts
---------   ------------------------
public      <HOST_NAME>
---------   ------------------------

We can see the HOST NAME.
The deployment fails because the configuration that was trying to set was already configured, as the host name was already present.


Resolution

After the Failed deployment 

Go to the DD putty and run the following commands.

1. snmp disable

2. snmp enable

3. Then try to manually delete snmp community
snmp show rw-communities
snmp del rw-community public hosts <HOST_NAME>

4. before running the configuration, make sure that 
snmp show rw-communities does NOT show the <HOST_NAME> 





If you face error while manually trying to add or delete the snmp community , Please involve Data Domain support for assistance.




And then redeploy the DPA from ACM it should be successful after the changes made
