D.2 Preparations for Firmware Updates
On any given system some preparations may be needed to perform
system firmware updates.
D.2.1 Partitions
LFU cannot update a partitioned system. Operating systems must be
shut down and if the system is hardware partitioned, an SCM command
must be issued to remove them. LFU must be run from the master
SCM.
