Abstract

Disclosed is a system that performs hardware diagnostics for a cluster of machines. This system distinguishes between different types of analysis, thus allowing the user to offload much of the data processing to a processor of his choice.

Distributed Diagnostics

      Disclosed is a system that performs hardware diagnostics for a
cluster of machines.  This system distinguishes between different
types of analysis, thus allowing the user to offload much of the data
processing to a processor of his choice.

      This system contains a single Diagnostic Controller and
multiple Diagnostic Applications.  The Diagnostic Controller manages
the testing of devices across the cluster, by invoking Diagnostic
Applications to test the individual devices.

      This system supports the automatic invocation of the Diagnostic
Controller on a backup processor should the host processor become
separated from the cluster.  The user is also allowed to name both
the primary and backup processors to be used.  This information is
stored in a profile which is maintained by the Subsystem Resource
Controller.

      The Subsystem Resource Controller resides on each member of the
cluster, and is used to start, stop, and restart the Diagnostic
Controller.  It monitors the presence of each member of the cluster,
by periodically sending messages to its counterparts.  This message
protocal also supports the remote invocation of a Diagnostic
Application.  The Diagnostic Controller does not directly start a
Diagnostic Application, but provides its name and the machine which
it should be started on to the Subsystem Resource Controller.

      Should the member bearing the Diagnostic Controller become
seperated from...
