This indicates whether this SAN connectivity template is "initial," a one-time starting configuration a service profile can later diverge from, or "updating," one that keeps every service profile using it in sync with future template changes. This distinction matters operationally, since an updating template will silently push future edits out to every service profile that uses it, while an initial template will not. For example, an admin editing an updating SAN connectivity template to change its QoS policy would automatically change that setting on every vHBA in every service profile derived from it.
