SCSI Bus Conditions SDLT 600 SCSI Interface Guide

2-4 January 2005 81-81200-02 REV A01

2.3.2 Reset Condition

The SDLT tape drive responds to bus reset conditions as follows:

• Within 250 milliseconds—and typically under 4 milliseconds—after a bus reset, the drive

responds to SCSI bus selections and returns the appropriate normal responses. Tape motion

commands are returned with Check Condition status, Sense Key of Not Ready, until the drive

makes the medium ready.

• The drive rewinds the tape medium to Beginning of Partition (BOP, which is Beginning of Tape

[BOT]).

NOTE: The SDLT tape drive does not implement the hard reset alternative for bus

RESET processing.

The SDLT tape drive recognizes multiple bus resets in succession as well as bus resets of arbitrarily

long duration (power-on conditions). It recovers within the time limits specified above following the

last bus reset.
