Symptoms
There are errors in the DPA collecting logs that indicate a conflict with either a report, schedule, time period or time period window. This will cause not all the required reports chosen in the SRM SolutionPack to be created on the DPA GUI.
In this example Recoverpoint, Data Domain and NetBackup were chosen in the SolutionPack, but only NetBackup appeared in the list of reports on the DPA GUI. Following are examples of the different errors seen in the collecting logs:

Cause
When the DPA SolutionPack is reconfigured or restarted it attempts to build and schedule reports in the DPA GUI for the collections the customer has chosen in the SP. In this case, there are already reports, schedules or time periods and time period windows configured in the GUI that conflict with the tasks SRM is attempt to complete.
Resolution
The conflicting SRM (W4N) reports, schedules or time periods and time period windows need to be deleted from the DPA GUI. (It will be best to delete all these W4N objects.)
The first step is to stop of SRM DPA Collector. This can be done in the SRM GUI or through /opt/APG/bin/manage-modules while logged into the collector server.
To delete W4N reports:
- Go to DPA GUI-> Reports->Report Jobs->Scheduled Report.
- Click on the show Filter icon .. search for the W4N reports.
- Highlight each report and hit the Delete button.
- Now check the Dashboard Scheduled Content tab for W4N reports.
- Recheck that no W4N reports exist in either tab.
To delete SRM Customized Reports
- Go to DPA GUI->Reports->Report Templates->Custom Report Templates.
- Click on the show Filter icon .. search for the W4N reports.
- Highlight each report and hit the Delete button.
- Now check the System Report Templates tab for W4N reports.
- Recheck that no W4N reports exist in either tab.
To delete SRM Schedules:
- Go to DPA GUI->Admin->System->Manage Schedules.
- Look thru or filter the list of schedules for W4N schedules for Avamar, NetBackup, NetWorker or Tivoli.
- For Recoverpoint and Data Domain, look for 15MinInterval, 1HourInterval or 5MinIntervalDPA.
- Delete them.
To delete SRM Time Periods and Time Period Windows:
- Go to DPA GUI->Admin->System->Manage Time Periods.
- The names of time periods and time period windows do not contain W4N, but do include Avamar, Netbackup and Networker ... see the list below
- Look thru the list of time periods for the above names or use the filter function.
- Time periods cannot be deleted if there is an existing time period window associated with the time period .. see example error below.
- Time period windows are difficult to find. These need to be checked even if you do not see the above error. Following is our current method:
- in the Manage Time Periods window click "Create Time Period".
- in the new Windows Properties window click Edit times.
- there should now be a list of time period windows.
- delete any Avamar, Netbackup and Networker time windows that include "last hour offset by 15 mins".
- In the Manage Time Periods window, delete any references to Avamar, Netbackup and Networker that include "15 mins ago or "1 hour and 15 mins ago".
The last step is to restart the SRM DPA Collector, Again, this can be done in the SRM GUI or through /opt/APG/bin/manage-modules while logged into the collector server. Once the GUI has been restart, go back to the DPA GUI and do a refresh. All the reports for the the options the customer chosen in the DPA SolutionPack should now be available.
