The DISPLAY SSI command displays status information about all subsystems defined to the SSI. You can request information for all subsystems at once or for those subsystems which meet the criteria specified by the filters used when issuing the DISPLAY SSI command. You can use filters to limit the information displayed to:

• One particular subsystem or those subsystems whose names match a specified pattern
• Subsystems that are either dynamic or not dynamic
• Subsystems that are either active or not active
• Subsystems that respond to a given list of function codes.
