Testing a single slot 0 board in a domain with no slot 1 board

The following information was provided by David Lafko (CPRE):

Testing a slot 0 board in a domain with no slot 1 can be done. The following steps will guide you through doing this. The example shown below assumes domain 'R' is unused and the system board we are wanting to test is SB8.

% addboard -d R -c assign SB8

% setkeyswitch -d R standby

% hpost -d R -Pno_ioadapt_ok -Pno_obp_handoff

The advantage of specifying the postrc directives on the command line is that you don't have to set up any special postrc file.

If you want to specify a diag-level, then you add another parameter to the hpost command depending on the level you would like post to run:

% hpost -d R -Pno_ioadapt_ok -Pno_obp_handoff -P"level 64"

The 'no_ioadapt_ok' directive allows for the testing of cpu boards alone:

no_ioadapt_ok 
    Intended Use = Service/Ops (2) 

	Since the operating system cannot boot without I/O, the number of I/O adapters 
	is one component of the configuration Figure of Merit (FOM) used to evaluate 
	configurations. No I/O adapters results in a 0 FOM.  For board bringup, however, the 
	user sometime want POST to continue testing even with no I/O installed. This 
	command tells POST to pretend there's one I/O adapter present when calculating 
	the FOM if there is actually none. 
                  

See the Sun Fire 15K POST .postrc Command Reference Page for more information regarding all of the .postrc directives.
