[c-nsp] Sup720 ignores boot variable

[Adrian Turcu]

This may help with your issue:

Q. What is the difference between the SP and RP bootflash/bootdisk?
A. SP bootflash/bootdisk is the location from where the system can load and boot a Cisco IOS Software image. The more SP bootflash/bootdisk space you have, the greater the number of Cisco IOS Software images you have, and the greater the choice in what Cisco IOS Software images you can boot from. An image can be loaded from the SP bootflash/bootdisk using the command boot system flash sup-bootflash:IOS-image-name. Multiple boot system flash commands can exist in the configuration file, and it is the first in the list that will be used as the image from which to boot the system. The RP bootflash can also be used as a storage location for Cisco IOS Software images, although the system cannot directly load an image from that location. The SP and RP bootflash can also be used as a storage location for backup and alternate configuration files. Configuration files that are required to be used as an active configuration must be copied over to the running or startup configuration.

I am using the followings in various Sup720 and the bootvar always looks identical and the systems always boot the correct IOS:

boot system flash bootflash:IOS-image-name
boot system bootflash:IOS-image-name
boot system sup-bootflash:IOS-image-name

6500-1# show bootvar
BOOT variable = bootflash:IOS-image-name;
CONFIG_FILE variable =
BOOTLDR variable =
Configuration register is 0x2102
