Using the CLI Command While Upgrading

When upgrading HP SIM integrated Storage Essential (SE), if you are logged in with a different user name to perform an upgrade (other than the original user name that was used to do the initial installation of the product), the corresponding (different) user is created in HP SIM and SE. That SE user is automatically associated with an SE role of SIMViewOnly. In addition, the SE user is also mapped to the default admin user in SE. If the installation user's SE role is different from the default SE admin user's role, attempts by the installation user to use the SE command line may result in “NoSuchElement” exceptions displayed in the command line window. To prevent this, assign the installation user a role, within Storage Essentials, that is the same as the default admin user. See ”About Security for the Management Server” on page 137 for more information.
