Robot Error status code 9

Message: Error in SEMAPHORE operation

Explanation: A process was unable to perform a semaphore operation (such as lock or unlock) associated with the resources maintained by ltid. (ltid is the Media Manager device daemon on UNIX and Linux or the NetBackup Device Manager service on Windows.)

Recommended Action:

  • Examine the command output, debug logs, and system 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.

  • On UNIX and Linux servers, gather the output of the ipcs -a command to see the resources that are currently in use.
