Run the Exec mode show boot 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).
Important
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# configure
[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# configure
[local]host_name(config)# boot system priority number image image_url config cfg_url
For information on using the boot system priority command, refer to the Adding a New Boot Stack Entry,
on page 92 .
Synchronize File Systems
Synchronize the local file systems on the management cards by entering the following command:
[local]host_name# filesystem synchronize all
Save the Running Configuration
Save the currently running, upgraded configuration prior to rebooting the chassis.
To save the running configuration to the current configuration file, enter the following command:
[local]host_name# save configuration /flash
Reboot the System
Reboot the system by entering the following command:
[local]host_name# reload [-noconfirm]
As the system reboots, it loads the new operating system software image and its corresponding CLI
configuration file using the new boot stack entry configured earlier.
After the system reboots, establish a CLI session and enter the show version command to verify that the active
software version is correct.
Optional for PDSN: If you are using the IP Pool Sharing Protocol during your upgrade, refer to Configuring
IPSP Before the Software Upgrade in the PDSN Administration Guide.
Verify the Running Software Version
After the system has successfully booted, verify that the new StarOS version is running by executing the Exec
mode show version command.
[localhost_name# show version
