Users Guide

● During this stage, the show boot detail command displays the details of the previous image that was installed.
The boot system active | standby command is not applicable during this state.
● If you install a new image using the image install command, the current staging image is replaced with the new
image that you have installed and you cannot downgrade to the previous version.
9. Reload the new software image in EXEC mode. This command performs a fresh installation of Release 10.5.0.0. Release
10.5.0.0 is installed as both the active and standby images.
OS10# reload
10. Use the show version command in EXEC mode to verify that the downloaded OS10 image is installed as the current
running version.
OS10# show version

11. If the saved configuration from Release 10.5.0.0 (or the earlier release to which you are downgrading to) is available, apply
the saved configuration and license files, and reload the switch.
OS10# copy ftp://userid:passwd@hostip/filepath/10.5.0.0-startup.xml config://
startup.xml
OS10# license install scp://user:passwd@hostip/0A900Q2-NOSEnterprise-License.xml
OS10# reload
NOTE:
While reloading, if the CLI prompts to save, select no for the save option. Selecting yes overrides the
configuration that was copied earlier.
12. If the saved configuration file from Release 10.5.0.0 (or the earlier release) that you are downgrading to is not available,
apply the backup text configuration (.txt) taken in Step 3. Ensure that the backup configuration text file does not have any
unsupported commands (commands that are introduced in later releases). If unsupported commands are present in the text
file, the system errors out. You might have to reload the switch, if any of the configurations require a reload.
OS10# copy ftp://userid:passwd@hostip/filepath/backup-running-configuration.txt
running-configuration
OS10# write memory
OS10# reload
Roll back from 10.5.2.0 or later release to 10.5.0.x or earlier release
Use the rollback script that is bundled with your OS10 software image to move to an earlier release. Using the rollback script
retains the earlier configuration and license information. You can use the rollback option only when the previous image is
available in the system as the standby image. Use the show boot detail command to view the version of the standby
image.
NOTE: The rollback script reboots the OS10 switch immediately.
To roll back, from the Linux shell prompt, enter:
OS10# system bash
bash (OS10) $ sudo os10-rollback-to-old-image
NOTE:
After rollback is complete, the system comes up with the previous release. However, the standby image becomes
nonbootable. To boot using the standby image, you have to install the image again using the image install command.
