System load/dump copies the contents of processor memory to or from a
remote system.
Throughout this document, the term boot is used to mean the process of
causing a system to initialize itself. Initialization may include
loading system memory.
A
boot command is a cause. The term load
is
used
to
mean the Drocess of transferring a system image into processor
memory from some source. This is one potential effect of a boot
command. The source of major interest in this specification is
a
remote system, accessed via a communication channel.
1.2 Design Scope
The low level maintenance operations require certain characteristics
to be present, attempt to meet certain goals, and lack some features
that are not within the scope
of
the design.
1.2.1 Requirements
The maintenance operation design must have the following
characteristics:
.
The functions previously mentioned must be included in the
design.
.
Active and passive sides of maintenance operations can be
implemented and used independently. The three categories of
maintenance operations are inter-dependent only in simple,
clearly defined ways.
.
Effects of errors (such as operator errors, protocol errors,
and
hardware errors) are minimized, always leaving
a
system in
a well defined state.
.
It
must be compatible with inter-company standard Ethernet
loopback protocol.
.
Implementations may select subsets of functions based on
particular product need.
1.2.2 Goals
The maintenance operation design tries to have the following
characteristics:
.
Functions and protocols are upward compatible with the
DNA
