4-12 Quantum DLT 8000 Tape System
4.2.15 SYNCHRONOUS DATA TRANSFER REQUEST Message (01h)
NOTE
The tape drive supports initiating synchronous transfer negotiations with the host,
but this feature is disabled by default. To enable it, set the MODE SELECT VU
ERROM parameter EnaInitSyncNeg.
This extended message allows the target and initiator to agree on the values of the
parameters relevant to synchronous transfers. The tape drive will not initiate the
Synchronous Data Transfer Request message; it relies on the initiator to do so. The
Synchronous Data Transfer Request command has the format shown in Figure 4-4.
