Create a new boot
stack entry for the new file group, consisting of the new operating system
image file and the currently used CLI configuration file by entering the
following Global Configuration command:
[local]host_name(config) boot system priority number image image_url /flash/filename config cfg_url /flash/filename
Assign the next
highest priority to this entry, by using the N-1 method, wherein you assign a
priority number that is one number less than your current highest priority.
Run the Exec mode
command to verify that there are less than 10 entries in the boot.sys file and
that a higher priority entry is available (minimally there is no priority 1
entry in the boot stack).
If priority 1 is in
use, you must renumber the existing entries to ensure that at least that
priority is available.
The maximum number
of boot stack entries that can be contained in the boot.sys file is 10. If
there are already 10 entries in the boot stack, you must delete at least one of
these entries (typically, the lowest priority) and, if necessary, renumber some
or all of the other entries before proceeding. Use the no boot system priority
command to delete a book stack entry.
[local]host_name(config) no boot system priority number
To add new boot
stack entries to the boot.sys file enter the following commands:
[local]host_name(config) boot system priority number image image_url config cfg_url
