Great find from Oscar Perez over on the HP ITRC Forums. This tag is not documented in the current HP Scripting guides and I wish I knew about it before I logged in by hand to 200ish iLO devices to manually update the setting.
What the tag does is tell the iLO to general a CSR for an SSL Certificate using a FQDN rather than a short name. If you identify iLO devices in DNS with a subdomain (e.g. server.ilo.mydomain.com) you need to do this.
