13. Once the package upload is successfully completed, set the package as the default
package file to be used by the server whenever it restarts.
a. From the SSLoader main menu select "Package Menu."
b. From the displayed package menu, select "Select Default Package."
If the correct firmware package is now listed, select it from the available
list. The server will then validate the data integrity of the package file.
If the validation is successful, exit from the package management menu and
choose "Continue Booting" from the main menu.
If the firmware package is still not listed, or the package fails
validation, attempt to reload the firmware package again (see step 12) or call
Hitachi Data Systems Technical Resource Center (TRC).
