SCSI Commands
5-162 Quantum DLT 7000 Tape System
SEND DIAGNOSTIC Command (1Dh) (continued)
NOTE
Because of data generation and verification, this test only streams
the tape for short periods of time. If Block Count is set very high,
the test can take many minutes or even many hours to complete.
If the specified diagnostic test passes, a GOOD status is returned. Otherwise, a
CHECK CONDITION is generated and the Sense Data contains information
about the failure.
