Enterprise SmartLock Directories on Isilon and Superna Eyeglass

We have an environment of Isilon Gen6 nodes. One for production and another for DR. SyncIQ is running Active Passive, Prod >> DR

We are planning to install Superna Eyeglass for Failover and DR readiness. I have question regarding the Failover and failback activities for Smartlock directories.

Lets see when Prod site is havng issues and we failover users to DR and user writes new data on DR. During failback when we sync data from DR to Prod using resync Prep and mirror job in eyeglass. Will they be able to write data on Prod Smartlock directories ?

Any suggestions most welcome.
