These platforms support the following options to boot the system:
internal flash at the rear of the node (cf1:\)
external USB flash (uf1:\)
network (with auto-init mode)
network (without auto-init mode)
Because multiple storage locations are available for the bootstrap image boot.tim file on the 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C, these platforms do not support the golden bootstrap image.
During bootup, the bootrom searches for the boot.tim in the following locations in the specified order, and uses the image obtained from the first location where boot.tim is found to load the bootloader:
cf1:\ (SD card slot or USB slot)
uf1:\ (external USB)
Users must plug in a USB storage device or SD card, with the correct TiMOS images into one of the supported locations before powering on the system.
If the boot.tim bootstrap image is not found in any of these locations, the boot procedure fails. If the boot.tim image is found, the system searches for bof.cfg (the boot options file) on the same storage device in the root directory. For example, if boot.tim is found on cf1:\, the system also looks for bof.cfg in cf1:\bof.cfg.
If bof.cfg is found, the system uses the BOF to locate the TiMOS software (both.tim file), configuration file, and other boot parameters, and processes them to boot the system. If the BOF is not found, the system attempts to retrieve the BOF from the network using the auto-init mode and create a new BOF as part of the auto-init process.
See the appropriate 7210 SAS chassis installation guide for more information about booting the system using these options.
