Description
This subdisplay shows the current host port SCSI target identification, any
initiator which has negotiated synchronous transfers, and the negotiated
transfer method currently in use between the controller and the initiators.
This subdisplay is available only for SCSI based HS array controllers.
SCSI host port target ID.
Transfer width. W indicates 16 bit or wide transfers are being used. A space
indicates 8 bit transfers are being used.
The initiator with which synchronous communication has been negotiated.
A numeric value indicates the synchronous data rate which has been
negotiated with the initiator at the specified SCSI ID. The value is listed
in megahertz (Mhz). In this example, the negotiated synchronous transfer
rate is approximately 3.57 Mhz. To convert this number to the nanosecond
period, invert and multiply by 1000. The period for this is approximately 280
nanoseconds.
Async indicates communication between this target and all initiators is
being done in asynchronous mode. This is the default communication mode
and is used unless the initiator successfully negotiates for synchronous
communications. If there is no communication with a given target ID, the
communication mode is listed as asynchronous.
