OpenStorage Technology (OST) backup logging

Figure: OST configuration

OST configuration

In this scenario, the client backs up the data directly to the media server and the media server accesses the vendor plug-in to transfer the data to the storage server.

For logging that is specific to OST, enable the following on the media server or plug-in host:

  1. In the registry or bp.conf file, set VERBOSE = 5.

  2. Ensure that the following directories exist under /usr/openv/netbackup/logs (for Windows, use install_path\NetBackup\logs):

    • bptm

    • bpbrm

    • bpstsinfo

  3. Create the volmgr/debug/tpcommand directory.

  4. Put VERBOSE in the vm.conf file.

  5. Set DebugLevel=6 and DiagnosticLevel=6 for the following processes:

    • OID 178 (Disk Manager Service or dsm)

    • OID 202 (Storage service or stssvc)

    • OID 220 (Disk Polling Service or dps)

    • OID 221 (Media Performance Monitor Service)

    • OID 222 (Remote Monitoring & Management Service)

    • OID 230 (Remote Disk Manager Service or rdsm)

    • OID 395 (STS Event Manager or stsem)

    These OIDs all log to the nbrmms unified log file on the media server.

  6. Increase the vendor plug-in logging. Most vendors have their own plug-in logging that is in addition to what is logged within the NetBackup logs.

  7. Reproduce the backup failure.

  8. In Activity monitor > Jobs, open the job details and click the Details tab. It displays the media server host name that ran the backup and the bptm process ID number (PID).

    • Find a line similar to bptm(pid=value); this value is the bptm PID to locate in the bptm log.

  9. Extract the bptm PID found in step 8 from the bptm log on the media server. This step gathers only the single-line entries; review the raw logs to see the multi-line log entries. In the following examples, 3144 is the bptm PID:

    • Windows command line:

      findstr "\[3144." 092611.log > bptmpid3144.txt
    • UNIX/Linux command line:

      grep "\[3144\]" log.092611 > bptmpid3144.txt
  10. Gather the vendor specific plug-in logs that cover the dates from when the backup was started and when it failed.
