D.3 Firmware Updates
Two firmware update modes are available on GS80/160/320 systems: one
using LFU and the other using the SCM update command. Note that if
a microprocessor’s firmware is corrupt and it is in fail-safe loader
mode, the SCM update command must be used to load healthy
firmware.
D.3.1 Using LFU
LFU is a standard, fairly automatic, method used to update firmware.
Currently (August, 2000), LFU must be run from the master SCM in
systems that are not
hardware partitioned. LFU updates micros of the
same type in parallel and is faster than SCM update. LFU cannot be
used when a microprocessor is in FSL mode.
Example D– 7 Running LFU
Place the firmware CD-ROM in the master PCI box CD-ROM device.
