This morning I found this error message in the TSM schedule logs
ANS1315W (RC15) Unexpected retry request. The server found an error while writing the data.
Waiting for TSM server
The conclusion was there were insufficient mount points or scratch tapes were not available
It is imperative to place improved messages into the log files! These general messages can take some time to diagnose accurately. I’ll pass the message on to the Backup Engineers, so they can improve the return messages
