NetBackup status code: 648

Message: unable to send extent message to BPXM

Explanation: The bpsynth process cannot send extent information to the bptm or the bpdm process that was started to read a specified backup image to synthesize.

Recommended Action: This error indicates a communication problem between bpsynth and the bptm or the bpdm reader process on the media server. Ensure that the media server is accessible and that the bptm or the bpdm process is running on the media server. Examine the NetBackup error log for any errors that the following logged: bpsynth (on the master server) and the bptm or the bpdm reader process (on the media server). Examine the debug logs for bpsynth and bptm or bpdm for additional information. Rerun the synthetic backup job. If the problem persists, contact customer support and send the appropriate logs.

A complete list of required logs and configuration information is available.

See "Logs to accompany problem reports for synthetic backups" in the NetBackup Logging Reference Guide.
