Unable to add a Datastore to replication manager App set

Hi all,

We are running replication manager version 5.4, and the backup technique is snapview snap.

The backup is running smooth so far.

But now, when I try to add a Datastore (a VNX 7500 LUN) to the Application Set, It is not adding.

It is runs for hours and then fails saying connection timed out.

We havn't done any changes since long, apart from adding Powerpath to our ESX servers.

What could be the issue here?

Regards,
