Present it right away, the RP splitter will hide access to the host until you go into the Test a Copy and go through the wizard. There is no reason to remove host access to the DR lun.
Hi there,  About a year ago we setup recover point for our data center move and it's just been rolling along with only a few CGs. Now, we are looking to finally utilize the solution for full fledged DR. I setup a SQL node to test and the luns have been replicating over to the DR site. I want to execute Test a Copy and failover for my first phase to detail what needs to be done. I am clear about everything, except I cannot remember when to present the luns replicated to host storage group on the DR array.   So the host that the volumes will be mounted on is zoned, and the HBAs are registered on the DR VNX array where the replicated volumes reside.   Thanks in advance! Admingirl
