Setting up a mirrored LUN with EMC Unisphere

A few weeks ago I wrote a blog about setting up vSphere SRM 5.0 with EMC Mirrorview.  Now that’s all well and good, but if you don’t have a LUN from your protected site being replicated to your recovery site, none of that will work!  A LUN is an acronym for Logical Unit.  It’s basically a portion of your storage that has been created on the storage side of things that you can present to servers (in the previous case ESXi servers).  In this blog, I’ll take you through the basic set up for replicating a LUN to the recovery site using EMC’s Unisphere GUI.  I’ll be using some SRM terms like “protected” and “recovery” sites to make things more clear.
