You may also enter a special character, either at the prompt or after
typing new data, for
scrolling through the fields. The special
characters are:
The power-up default for the packet address is the area which is
also used by the PBOOT and IOP commands for building packets.
IOC displays the command packet, and if you so instruct it, sends
the packet to the disk controller, following the proper protocol
required by the particular controller.
A device probe with entry into the device descriptor table is done
whenever a specified device is accessed via IOC.
The device probe mechanism utilizes the SCSI commands Inquiry
and Mode Sense. If the specified controller is non-SCSI, the probe
simply returns a status of device present and unknown. The
device probe makes an entry into the device descriptor table with
the pertinent data. After an entry has been made, the next time a
probe is done it simply returns with device present status
(pointer to the device descriptor).
V or v Go to the next Þeld. This is the default, and remains
in effect until changed by entering one of the other
special characters.
^ Back up to the previous Þeld. This remains in effect
until changed by entering one of the other special
characters.
= Re-open the same Þeld
. Terminate the IOC command, and return control to
the debugger
