BOF chassis-role and host-type parameters for 7210 SAS-Mxp, 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Sx 10/100GE

On the 7210 SAS-Mxp, 7210 SAS-Sx 1/10GE, 7210 SAS-S 1/10GE, and 7210 SAS-Sx 10/100GE, the operator can configure the chassis-role and host-type boot parameters to operate the 7210 SAS node in standalone mode or satellite mode. The values configured for these parameters must be consistent for boot up to proceed correctly. Table: 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE boot loader actions for chassis-role and host-type parameters describes the boot loader action when the chassis-role and host-type parameters are set to one of the allowed values.

The bof>host-type command can be set to one of the following values:

none (factory default setting)
standalone
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.

The following table describes the boot loader action when the chassis-role and host-type parameters are set to one of the allowed values.

Table: 7210 SAS-Mxp, 7210 SAS-Sx/S 1/10GE, and 7210 SAS-Sx 10/100GE boot loader actions for chassis-role and host-type parameters
Boot parameter: chassis-role	BOF parameter: host-type	Boot loader action
factory-default	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.
	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.
	satellites	The boot loader detects a mismatch and returns an error. Depending on the context of the boot loader, it will take one of the following actions: If the boot loader is in auto-init, it will retry auto-init to fetch a new BOF with the correct value for host-type. If the boot loader was interrupted to configure the BOF parameters manually, it will go back to provide an option for the user to change the value of host-type to the correct value.
	none	The value of chassis-role 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 if the host-type value is not set explicitly (that is, the value is set to none).
satellite	satellites	The chassis-role value is unchanged from satellite. The system boots up successfully in satellite mode. On subsequent reboots, the system will continue to boot up in satellite mode.
	standalone	The boot loader detects a mismatch and returns an error. Depending on the context of the boot loader, it will take one of the following actions: If the boot loader is in auto-init, it will retry auto-init to fetch a new BOF with the correct value for host-type. If the boot loader was interrupted to configure the BOF parameters manually, it will go back to provide an option for the user to change host-type to the correct value.
	none (host-type is not set to any value explicitly)	Not recommended
