CX4 CLARiiON Datasources failing with "Failed to parse host alias info"

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.

Re: CX4 CLARiiON Datasources failing with "Failed to parse host alias info"

EMC has posted another related KB emc241018 on this topic that might be worth a look - there is a procedure documented on remediating hosts whose initiators do not appear in Connectivity Status in Navisphere.
