Hello all. I am pretty new to VMware ESI 4.1 so this question will be basic to you. Class didn't do a good job of telling us how to do this. I don't have a lab so I will have to take your suggestions and work through them a little at a time.
We have a EMC CX4 and are implmenting a VMware 4.1 environment. I have the SAN experience but am just a little confused as to how to present the new LUNS to the hosts. Maybe I'm not typing in the correct search word in Google or something. DRS. I might still be looking at this from the SAN admins viewpoint, but here's my question.
We are going to be running three hosts with a vcenter server in a DRS setup. All the hosts will have fiber HBA's that attach to our EMC CX4. On a physical server, I would zone it, create a LUN and drop it in the storage group for the server. I'd then do a scan on the server and the lun would show up. Just for that server.
However, how do I do that for a cluster of VM Hosts? How do I create LUNS so if a host fails the other hosts in the cluster will see it. Do I drop all the hosts in the same Storage group in the EMC and then present the LUNS? Seems odd to me to do that. I'm confused because normally when I zone a physical box then nothing else see's the LUN I create except that host. How do I make it so all the hosts can see the datastore?
