Installation and User's Guide; they also are listed in the Storage Area Network Data
Gateway Router Service Guide.
diagBoot
Use the diagBoot command only to transition the SDG Router from normal
operation to the special diagnostic mode. The command first ensures that
the ffs0:mt directory exists, then it verifies that the files diagnstk.o and
diagnstk.rc are in the flash file system. If they are in the root directory, it
moves them to the ffs0:mt directory.
The diagBoot command copies the existing boot parameters to a file in the
ffs0:mt directory on the SDG Router. It then installs the new boot
parameters that direct the SDG Router to start using the special diagnostic
startup script, ffs0:mt/diagnstk.rc. It renames the persistent map file
config/device.map as config/device.bak. Finally, diagBoot issues a reboot
command to put the changes into effect.
