PowerScale: Initial NDMP Troubleshooting

To begin troubleshooting Network Data Management Protocol (NDMP), verify the following information for the impacted cluster and impacted NDMP jobs.

1. PowerScale name and version

2. What backup software and version are you using, Data Management Application (DMA)? Verify NDMP global settings.

   isi ndmp settings global view

3. Has this worked before?

4. Date & time the problem started, and/or timestamps of recent failures. (This is important for establishing a timeline and focusing searches through the logs.)

5. How often does the issue occur? Is the frequency of the problem intermittent or predictable?

6. What errors are you seeing? (copy and paste)

   Live cluster
   
   isi_for_array -QX 'grep -hi ndmp /var/log/messages' |sort |tail -50
   
   Logs
   
   cat */varlog.tar/log/messages |grep ndmp |sort |tail -50

   Share any error info from the DMA side too, such as a report from the failed backup job.

7. Were there any recent changes made? If yes, what changes were made?

8. What is your location and time zone?

9. What is the cluster's location and time zone?

10. Provide a full log set from the PowerScale cluster ***WHILE THE BACKUPS ARE RUNNING*** with the isi_gather_info command.

    For Performance issues, also collect the following:

11. What performance numbers are you seeing?
    Check throughput on running NDMP jobs.

    isi ndmp sessions list -v

12. What performance numbers are you expecting to see?
