Error description
Customers' may run into an issue when TSM discovers a serial number mismatch on a drive it attempts to open. This will happen when the drive we successfully opened reports a different serial number than what is stored in the TSM database, indicating that the wrong drive was opened. When the serial mismatch occurs, TSM attempts to resolve the mismatch with SAN discovery. However, if SAN Discovery fails or is disabled, then not only will TSM fail to open the intended drive, it will additionally neglect to close the wrong drive it had just opened while handling the SAN discovery failure or its disablement. Thus, there will be a SCSI reservation left on a drive that will not be released unless TSM or that drive is recycled. . If the above situation occurs, then the error number=16 will be seen on subsequent attempts to open the drive with a stale reservation leftover from this described behavior. Thus, the server reporting the error number=16 generally did not cause the problem, but was only affected by the aftermath of this situation. In many cases the TSM server or storage agent that left the stale reservation will throw an ANR8963E error message. . Customer/L2 Diagnostics (if applicable) Messages seen: ANR8779E Unable to open drive drive_name, error number=16 ANR8963E Unable to find path to match the serial number defined for drive drive name in library library nam .
