Automatic Dump Transfer

      Disclosed is a method for automatically detecting and
transferring a system dump from local system media to a file on a
remote system during system restart.

      When an operating system crash occurs on a diskless system
(i.e., a system with no local media), the system dump is written to a
predesignated file on a predesignated remote system.  On a dataless
system (i.e., a system with local media for paging and dumping), when
an operating system crash occurs, the system dump is written to local
media. The goal of this invention is to simplify the administrative
tasks of retrieving and examining system dumps from diskless and
dataless systems by making these tasks the same for both types of
systems.  This is accomplished by automatically detecting during
system restart of a dataless system whether a new dump is present and
automatically transferring the dump to a predesignated file on a
predesignated remote system.

      On a dataless system, when the operating system crashes and a
dump occurs, the time, size, and location of the dump is saved in
non-volatile memory.  When the system is rebooted, this non-volatile
memory is examined during operating system initialization, and if a
new dump is present, the dump is transferred from the local media
over a communications link to a remote system where the dump is saved
in a file.
