Explanation: The bpsynth process was unable to start the bptm or the bpdm process to read a backup image to be synthesized.
Recommended Action: Do the following, as appropriate:
Examine the NetBackup error log for any errors that bpsynth logged. For more information, refer to the following debug logs: for bpsynth on the master server and for bpcd and bptm or bpdm on the media server. Ensure that the bptm or the bpdm binaries on the media server are executable and are not corrupt. Try running bptm or bpdm commands locally on the media server to ensure that the binary is executable and not corrupt. For instance, you can run the following command
/bp/bin/bptm -count -rn 0 -rt 8
where robot number is 0 and the robot type is 8. The robot type that corresponds to the robot number can be taken from the command line that is logged in the debug log for bptm. This command displays the counts for the up, shared, and assigned drives in the robot.
A complete list of required logs and configuration information is available.
