Gigabyte BMCs must have their failover mode disabled to prevent incorrect network assignment.
If Gigabyte BMC failover mode is not disabled, then some BMCs may receive incorrect IP addresses. Specifically, a BMC may request an IP address on the wrong subnet and be unable to re-acquire a new IP address on the correct subnet. If this occurs, administrators should ensure that the impacted BMC has its failover feature disabled.
Check the failover setting on a Gigabyte BMC.

is used to prevent the password from being written to the screen or the shell history.
ncn# USERNAME=root
ncn# read -r -s -p "BMC ${USERNAME} password: " IPMI_PASSWORD
ncn# export IPMI_PASSWORD
ncn# ipmitool -I lanplus -U "${USERNAME}" -E -H BMC_HOSTNAME_OR_IP raw 0x0c 0x02 0x01 210 0 0
Example output:
11 00 00
The output can be interpreted as follows:
11 00 01
- failover mode is enabled.11 00 00
– failover mode is disabled (this is the desired state).Note: On Gigabyte BMCs, the default setting is for failover mode to be enabled. Therefore, if a Gigabyte BMC is reset to defaults for any reason, or upgraded, then failover mode must be disabled again in order to switch the BMC to manual mode.
