TRANSFER_RATE_REQUESTED=ASYNCHRONOUS
TRANSFER_RATE_REQUESTED=DEFAULT (Default: 10MHz)
TRANSFER_RATE_REQUESTED=10MHZ
TRANSFER_RATE_REQUESTED=5MHZ
___________________________ Note ____________________________
Set the same transfer rate for both controllers in a dual-redundant configuration.
____________________________________________________________
Specifies the maximum data transfer rate that HSZ controllers use when communicating
with a SCSI host. You may need to limit the transfer rate to accommodate long cables
between the subsystem and the host system.
Table 2–4 lists the maximum transfer rates for different lengths of fast and slow SCSI
buses. These lengths represent cable lengths plus shelf-bus lengths.
