Notes When Using RADIUS Authentication for ETERNUS Web GUI

A primary server and secondary server can be set as RADIUS servers. If the primary RADIUS server times out, the secondary server is tried.
If RADIUS Authentication fails and "No" (the internal authentication is not performed) has been selected for "Recovery Mode", it will not be possible to log in to ETERNUS Web GUI or ETERNUS CLI.
When "Yes (Communication error / Authentication error)" or "Yes (Communication error)" has been selected for "Recovery Mode", Internal Authentication is only performed if RADIUS Authentication fails on both primary and secondary RADIUS servers, and at least one of these failures is due to network error.
So long as there is no RADIUS Authentication response the storage system will keep retrying to authenticate the user for the entire "Retry Out Time" (sec.) period set on the [Set RADIUS Authentication] function. Authentication not succeeding before the timeout occurs is considered a RADIUS Authentication failure.
When using RADIUS Authentication, if the role that is received from the server is unknown (not set) for the storage system, RADIUS Authentication fails.
