5.1.6 Behavior at Power-On and SCSI Bus Reset
The following apply to the DLT 8000 tape drive’s behavior at power-on and/or SCSI bus
reset:
•
When the Quantum DLT 8000 system is powered up, all device SCSI lines are set to
high impedance.
•
The design of the DLT 8000 tape drive does not allow it to generate any spurious
signals on the SCSI bus at power-on.
•
Within five seconds of power-on, and within 250 milliseconds (typically under 4
milliseconds) after a SCSI bus reset, the DLT 8000 tape drive responds to SCSI bus
selections and returns appropriate, normal responses. Tape motion commands will
be returned with Check Condition status, Sense Key Not Ready, until the tape
medium has been made ready.
•
The tape drive implements the hard bus reset option.
•
The tape medium is rewound to Beginning of Tape (BOT).
The DLT 8000 tape drive recognizes multiple, successive SCSI bus resets and SCSI bus
resets of arbitrarily long duration. The tape drive recovers within the time limits
specified above following the last SCSI bus reset.
The tape drive goes through a calibration process at power up and loading of medium.
