boot delete
This command deletes the secondary installation.
Syntax
boot delete
Guidelines
A firmware upgrade with the boot image command retains current configuration data to restore the appliance to a known, stable state if necessary. The previous firmware image and associated configuration data is referred to as the secondary installation.
While you can use the boot delete command to delete the secondary installation, keep in mind that its deletion prevents firmware rollback as provided by the boot switch command. Therefore, do not delete the secondary installation unless directed by IBM® Support.
Example
Delete the secondary installation.
# boot delete
