DLT-S4 Interface Reference Guide 327
SET DEVICE IDENTIFIER Command (A4h/06h) 4
The SET DEVICE IDENTIFIER command requests that the device identifier
information in the DLT-S4 tape drive be set to the value contained in the
parameter list. This information is then accessible using the
REPORT
DEVICE IDENTIFIER
command. The device identifier is persistent through
Reset and power cycles.
On successful completion of a
SET DEVICE IDENTIFIER command, the
drive generates a
UNIT ATTENTION condition for all initiators except the
one that issued the command with the Additional Sense Code set to
DEVICE IDENTIFIER CHANGED.
