Delete replication session

Hi,

After a network migration, we want to reconfigure replication between our two vnxe3100.

Replication sessions were paused before migration, we modified network on our two vnx but when we want to resume the replication whe have an error.

We have tried to remove the replication sessions but we can't. On the destination VNX replication sessions are deleted but they are still here on our local VNX. When I try to delete it I have the following error :

"

The delete operation failed with the following error:

The system failed to delete the replication session.

(Error Code:0x650000d)

"

In "Hosts"->"Replication Connexions", connection between two host are ok in both vnx. In "System"->"System replication" I have replication session on local vnx but nothing on distant vnx.

How can i delete my replication sessions to be able to recreate it after ?

Thanks
