I recently setup Celerra Repliator v2 between an old NS to a new NS to migrate CIFS shares and VDM configuration. The replication worked great and replicated 3 TB of data in about 30 hours. Once replication was complete I switched over the files system and VDM replication sessions in Celerra Manager. The switcheover went great and I was able to access the CIFS server and shares on the new NS.
When I used Celerra Manager to view the CIFS shares and CIFS server on the new NS there was nothing listed on the shares tab or CIFS servers tab. I new the shares and server was there because I could use Computer Managment MMC to connect to the CIFS server name and vew the shares.
The only I found to get the CIFS shares and server to show up in Celerra Manager was to reboot the control stations.
Anyone else know of a way to update the control station without having to reboot it?

What code are you running? I had flakey things happen with 5.6.36. I upgraded to 5.6.42,
5.6.44
Did you solve this issue? I see the same thing happening here.
Thanks !

did you let the VDM fully replicate before replicating the FS’s? this is a requirement.
