Thanks Robobeat - but I am not sure if this tasks window shows whether teh sync has been completed. It seems rather that it shows whether the sync has been started or stopped.
So, when I came in this morning the RAIDs were both showing no activity, so the replication has somehow stopped, but there was no sign of that in the tasks window.
@Todd: no I didn't use the destination volume et all. In fact I didn't had any data on that iSCSI volume, because I wanted the initial replication to finish before I put data on that volume.
I have now removed the replication tasks and created a new one. Let's see, if this works out better this time.
I had yesterday setup my volumes again and this time replication has finished. Well, I think that this was the same the last time, but neither last time, nor this time did I get an e-mail from either of the two DSS'. I did get other e-mails from both, so e-mail notification is setup correctly.
You should receive email notification on events of the failover but not from the Status of the Volume Replication from the Source to Destination only if there was some failure to complete. Though we could look into future releases to have this event once the replication of the volumes is complete to send notification.
