TSM detected the problem described in APAR PK12572 . The server options file contains SKIPONZEROVERBBACKUPSET ON. TSM verified there was no further data on the volume, and skipped to the next volume.
Processing continues.
If the backupset volume was written before TSM 5.2.7, or 5.3.3 was put on the system and meets the PK12572 criteria, no action is required. If not, the volume has encountered a read error, and should read again on a server without the SKIPONZEROVERBBACKUPSET ON option to get the correct error messages for problem determination.
