Production to DR storage replication support (Netapp) for RHEV
Does RHEV support replicated storage for DR site ?
we are having NetApp storage in production as well as in DR. we are planning to use storage level replication so that DR storage will have exact copies of PR.
In that if we create VM in PR and replicate the underlying storage with DR, will it show the newly created unassigned LV for VM at DR storage domain ?
What is the solution for DR Site if we have storage feature such as replication ?
My objective is to have VM on PR and DR at same level in terms of disk, OS and application installed in it, so that in case of emergency if PR goes down, I can use DR site. Does Red Hat has any solution for this for RHEV ?

There was also a session on this at Summit 2014 (you may have to dig to find it):

There is a moderate amount of "messing about" to spin up the DR side of the equation if/when you decide to do so. The storage domains/volumes/network-interfaces/etc... are identified by UUID and need some attention to get everything working. But... it has been done and seemed pretty straight-forward from the presentation.
