7 Appendix: 7210 SAS Boot Procedures
This chapter describes the booting procedures for 7210 SAS devices.
This chapter provides information about booting a factory-shipped 7210 SAS device
for the first time. It also includes information to boot the 7210 SAS device after
subsequent reboots that are initiated by issuing the admin reboot command. For
subsequent reboots, the BOF and the TiMOS image are stored on the local flash.
The 7210 SAS supports two modes for a first-time boot of a factory-shipped node or
to boot the node after the admin>reboot auto-init command is executed. The
supported boot modes are:
• auto-init mode
In this mode, the boot procedure uses an external DHCP server to provide the
IP address and other IP parameters, and the BOF configuration, which contains
the image location and the configuration file location. This mode does not
require user intervention and provides an option for zero-touch provisioning of
the node.
This method also provides an option to modify the default values of the BOF
parameters used for auto-init and customize a specific set of BOF parameters
so that auto-init is supported in the customer network environment. See Auto-init
Mode for a list of BOF parameters that the user can modify.
The user requires console access to modify BOF parameters. After the partial
BOF is saved, the system continues using the auto-init mode procedure to boot,
with auto-init using the modified values of the BOF parameters that the user has
provided.
• manual mode
In this mode, the boot procedure requires user intervention to complete the
process. During the boot process, the user must log in to the console on the
node and configure the IP address, other IP parameters, and the location of the
image file and configuration file. The following options are supported to boot the
7210 SAS device in manual mode:
- boot from the image on flash
- boot from the network using uplink ports
- boot from the network using the OOB Ethernet management port
Table 96 lists the supported boot procedures for 7210 SAS devices.
