You cannot delete an OS distribution while it is being deployed through an OS profile. Wait until the deployment job finishes, then delete the OS distribution.
Delete all OS profiles that are associated with the OS distribution. This process includes deleting the default OS profile that was created when the OS distribution was copied. An OS profile cannot be deleted while it is being deployed. You may remove it after the deployment is completed. See To Delete an OS Profile for instructions.
Log in to the N1 System Manager.
Type the following command:

The distribution is deleted. See delete os in Sun N1 System Manager 1.3 Command Line Reference Manual for details.
View the available OS distributions.
N1-ok> show os all
