CX4s running 29 FLARE may be undiscoverable with SANscreen because they are incapable of successfully returning a full "getall" navi*cli output to SANscreen. If your CX4 datasource is failing with "Failed to parse host alias info", this is what you are experiencing. Once this problem starts, it is 100% consistent.
Our current understanding is that you need to have EMC resolve this, and there is not an end user procedure to resolve this. See EMC KB emc235848 , as the command cited in that KB also consistently fail as well. There is apparently a procedure to delete and re-add initators to a CX4.
