The SCSI Tape tests include the following: v SCSI Tape Buffer Test This test writes logical blocks of data to the internal buffer on the tape drive. The same logical blocks of data are then read from the tape drive buffer and compared to the original data. If the tape drive does not have an internal buffer, you cannot select this test. v SCSI Tape Read Test Use this test to make sure that the SCSI tape drive is reading correctly. This test reads sequential logical blocks from the SCSI tape. With default parameters, this 50 IBM xSeries 450 Type 8688: Hardware Maintenance Manual and Troubleshooting Guide
