Lets start over as if all users are using the NIS Authentication method to access the shares but the replication task was switched over.

Server A build 3518 (source for the NAS Logical Volume LV000x) using Authentication method NIS

Server B build 3518 (destination for the NAS Logical Volume LV000x) using Authentication other then NIS?

Server B was switched to be Source server and Server A was switched to Destination server.

Once this was done you were not able to see your shares?

When the replication is started only the source will be seen not the destination until it is switched over and roles are reversed.

I am willing to do a webex session to help but we will need to setup a time schedule. I am located in the EST time zone.
