The CLI - sysparaid

Use the command sysparaid to verify the validity of a system partitioning configuration without invoking the GUI. Optionally, you may request the corresponding layout files be constructed and saved for activation later.

The CLI sysparaid is invoked by the GUI spsyspar to handle a graphically specified layout. In that case the spsyspar code constructs the necessary input data and option specifications for the user.

When working with sysparaid directly, you must provide these inputs and options. The syntax for the CLI is shown below. For complete syntax, see the book PSSP: Command and Technical Reference.

     sysparaid [-s layout_name | a_fully_qualified_path]
     input_file [topology_file]

where:

The input file must specify the size of the system, number of partitions to be used, which nodes are in which partition and so on. The format of the input file is shown in Figure 46 and the file shown is shipped with PSSP in thessp.top file set as the inpfile.template file in the directory /spdata/sys1/syspar_configs/bin.

Recall the Sample System of Figure 39, and the Alpha and Beta partitions of Figure 40. An input file for sysparaid which specifies that layout is the my_part_in file presented in Figure 47.

You could execute sysparaid as follows to check for validity:

                 sysparaid  my_part_in
 

(If the global system topology file is not present in the /spdata/sys1/syspar_configs/topologies directory, you must provide that topology file.) sysparaid examines the inputs and recognizes that this layout is equivalent to the layout shipped by IBM as:

      /spdata/sys1/syspar_configs/1nsb0isb/config.8_8/layout.3
 

If sysparaid did not find an existing equivalent layout, it would report that the layout is valid, and you could rerun sysparaid specifying the -s (save) option with a directory in which to place the results. The results would consist of

layout.desc
file describing this system partitioning layout;

nodes.syspar
file with shorthand listing of partition contents;

spa.snapshot
file listing ownership of switch chips by partition;

syspar.1.Alpha
directory for Alpha - node list, topology, snapshot, metric files;

syspar.2.Beta
directory for Beta - node list, topology, snapshot, metric files.
