https://community.hpe.com/t5/disk-enclosures/replace-failed-path-on-eva-4400/m-p/5355355#M44973 Hey, well, you have the 'hosts' in Command View. In them I believe you have the WWN for the HBA port. pWWN. I don't think you have the node WWN in there, but if you do then moving the cable to the other port would not require any configuration on the array side.<BR /><BR />If it is the pWWN, and you move the cable to the other port, then you need to add the new pWWN on a host in Command View.

I have an EVA440 with dual controllers, each with redundant fiber connection, direct attached to rp7420. One fiber channel on dual channel card has failed on the server. Question - can I add redundant cards and switch to one of them or must I replace at the exact same hdwe address? I would like to be able to recover a link to another device without having to open up the server. thanks</P> Thu, 06 Oct 2011 21:28:17 GMT https://community.hpe.com/t5/disk-enclosures/replace-failed-path-on-eva-4400/m-p/5355101#M44971 Dave Chamberlin 2011-10-06T21:28:17Z https://community.hpe.com/t5/disk-enclosures/replace-failed-path-on-eva-4400/m-p/5355355#M44973 Hey, well, you have the 'hosts' in Command View.
