question: public static boolean areBackendInitiators ( List < Initiator > initiators ) { boolean backend = true ; for ( Initiator initiator : initiators ) { if ( ! NullColumnValueGetter . isNullURI ( initiator . getHost ( ) ) && URIUtil . isType ( initiator . getHost ( ) , Host . class ) ) { backend = false ; break ; } } return backend ; }
target:  Checks if any of the initiators belongs to a true Host and returns true if all initiators do not belong to a host. This effectively checks if all initiators are for an RP or vplex system because the host id is set to null for these initiators.
