Boot options
factory. In the factory-default setting, the user can use auto-init to retrieve the BOF and boot the node
in either standalone or satellite mode by setting the host-type parameter in the BOF.
By default, the boot loader assigns a value of none to the host-type parameter and uses this value if
the host-type parameter is not explicitly received in the BOF. As a result, in the factory-default setting,
the user can boot the node in standalone mode without setting the host-type parameter to an explicit
value (which maintains backward compatibility).
• standalone
This parameter setting forces the node to operate in standalone mode. In the standalone setting,
the host-type parameter value in the BOF (retrieved through auto-init, present locally, or configured
manually) must be set to either standalone or none. If host-type is set to satellites, the boot loader
detects a mismatch and does not boot up.
• satellite
This parameter setting forces the node to operate only in satellite mode. In the satellite setting,
the host-type parameter value in the BOF (retrieved through autoinit, present locally, or configured
manually) must be set to satellites. If host-type is set to standalone, the boot loader detects a
mismatch and does not boot up.
The following table describes the boot loader action when the chassis-role and host-type parameters are
set to one of the allowed values.

Boot parameter:
chassis-role
BOF parameter:
host-type
Boot loader action
satellites
• The user sets chassis-role to satellite.
• The system boots up successfully in satellite mode.
• On subsequent reboots, the system will continue to boot up in
satellite mode.
standalone
• The user sets chassis-role to standalone.
• The system boots up successfully in standalone mode.
• On subsequent reboots, the system will continue to boot up in
standalone mode.
factory-default
none
(host-type is not
set to any value
explicitly)
• The chassis-role value is unchanged from factory-default.
• The system boots up successfully in standalone mode.
• On subsequent reboots, the system will continue to boot up in
standalone mode, if the value of host-type is not set explicitly
(that is, it is set to none).
standalone standalone
• The chassis-role value is unchanged from standalone.
• The system boots up successfully in standalone mode.
• On subsequent reboots, the system will continue to boot up in
standalone mode.
