The Create OS Profile wizard incorrectly shows ja_JP.EUC_JP as a selection. If ja_JP.EUC_JP is selected, then the load OS process will fail.
Workaround:
Specify ja_JP.UTF-8 when creating the OS profile: and deploy it to the provisionable server, for example:
N1-ok> set osprofile osprofile_name language=ja_JP.UTF-8
Deploy the profile using the load server command or the Load OS wizard in the browser interface.
Log in to the provisionable server as root, and open the /etc/default/init file for edit.
Replace the text ja_JP.UTF-8 with ja_JP.eucJP, then save and close the /etc/default/init file.
