System Management System command reference
iMG/RG Software Reference Manual (System Configuration)

Following the example in Figure 1-4; when the configuration file “boot2” is set to be the bootstrap configura-
tion file via the system config set command (phase B), the backup process first copies the content of
the active configuration partition (now the second partition) to the backup configuration partition (the first
partition). It then updates the im.conf file in the backup configuration partition to be a copy of the new config-
uration file “boot2” and increments the content of file version in the backup config partition to be one value
higher than the active configuration partition.
At this point, if the gateway restarts the rule of the two partitions are swapped yet again. The first partition will
be the active configuration partition while the second will be the backup.
If during the system config set command, the gateway restarts or power-cycles, only the backup configuration
partition (the first in the example) will be corrupted, leaving the second configuration partition responsible for
configuring the gateway and preserving the original bootstrap configuration file as well as the newly generated
(from Phase A) configuration file.
Note: When a configuration partition is corrupted, the first system config create or set command will cause the
backup process to format and restore the invalid partition so it can receive a copy of the current active
configuration partition.
