The display commands can produce large amounts of output data. Listing
control is built into these commands to limit display pages to 24 lines or less.
As with the parameter prompts, a '.' or 'x' entered at a paging prompt causes
the command or t167 to terminate.
Build sdl_cmd Structure
This command is used to completely configure a t167 control structure prior to
the execution of an SDL command. Any allocated control structure may be
configured. The user is asked to provide information regarding the type of
command to be built.
Refer to Tables E-1 and E-2 for a list of the SDL commands. In general, an
sdl_init followed by an ATTACH command must be the first commands sent
to the SDL. As shown in the tables, some commands are allowed prior to the
ATTACH.
If the command is ATTACH, a list of supported devices is displayed. Upon
selection of a supported device, all defined parameters for that device are
copied from a statically-configured area to the selected control structure.
Information regarding device-specific configuration is discussed in the section
Adding SDL Tools Support For New Devices later in this appendix.
Issue sdl_init Command
The SDL is entered through the sdl_init entry point. Unless specified on the
command line, the user is prompted for scsi_addr, intr_lvl, clk_speed, and
snoopmode values. Return status is displayed upon completion of the
sdl_init command. Chapter 3 describes these parameters in the siop_init call
(they are the same as for the sdl_init call).
Issue sdl_read Command
The SDL is entered through the sdl_read entry point. Unless specified on the
command line, the user is prompted for an allocated control structure number.
Status is displayed upon completion of the sdl_read command.
If the 'c' option is selected, the current (last specified) control structure is used.
A control structure may not be specified if this option is selected.
Command format: sdl_init <scsi_addr> <intr_lvl> <clk_speed> <snoopmode>
Command format:
sdlread [-c]
sdlread <control_structure>
