• satellites
The chassis-role boot parameter (not available in the BOF) can be set to one of the
following values:
• factory-default
By default, the chassis-role boot parameter value is set to factory-default
when the 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, 7210 SAS-Sx 10/100GE
and 7210 SAS-Mxp are shipped from the 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.
Table 22 describes the boot loader action when the chassis-role and host-type
parameters are set to one of the allowed values.
