Diagnosis Guide

Requisite function

This is a list of the software directly used by the PSSP software related to all servers. Problems within the requisite software may manifest themselves as error symptoms in this software. If you perform all the diagnostic routines and error responses listed in this chapter, and still have problems with the server, consider these components as possible sources of the error. They are listed with the most likely candidate first, least likely candidate last.

• The System Monitor (hardmon) must be running on the control workstation.

  The external hardware daemons consist of two interfaces: the frame supervisor interface and the node supervisor interface.

  • The frame supervisor interface is responsible for keeping the state data in the frame's packet current and formatting the frame packet for return to the hardmon daemon.
  • The node supervisor interface is responsible for keeping the state data in the node's packet current. The node supervisor is also responsible for translating the commands received from the frame supervisor interface into SAMI (Service and Manufacturing Interface) protocol, before sending them to the service processor on all servers.
• The System Data Repository (SDR) subsystem

  The System Monitor requires the SDR subsystem. For more information, refer to Diagnosing SDR problems.

• SP System Security Services

  Principal and group names for DCE entities use the default SP chosen names. These may not be the actual names on the system if you have overridden them using the spsec_overrides file.
