Yup, that's it! It will keep the setting so you don't need to do it each time (though you may want it in case you drop a server HBA or something).
I get emails from the Compellent controllers saying connectivity is lost.  Do I just need to check the  "Do not show alerts when connectivity to this server is lost" box before powering the server off to stop these emails for that time?  Cheers,  Bilal
