Media Manager status code 71
Explanation: An attempt to write data to a vmd socket failed. vmd is the NetBackup Volume Manager daemon (UNIX and Linux) or NetBackup Volume Manager service (Windows).
Recommended Action:
Examine the command output (if available) and the daemon and reqlib debug logs for a more detailed message on the error.
See "Setting Media Manager debug logging to a higher level" in the NetBackup Logging Reference Guide.
Identify the system where vmd is running. The system usually is termed the Media Manager host or the EMM server and it defaults to the local system in some user interfaces. Possible causes for the error are a high network load, missing operating system patches or service packs, or an unexpected vmd process failure.
