In Unity 300, Failback tooks 4 hours to complete from Destination Unity to Source Unity
Hi All,
We are using Unity 300 with RecoverPoint/Async 5 Minutes. We did failover with Sync from Source Unity.
Q1- A LUN having 4 TB size took almost 4 hours to failback from destination Unity to Source Unity. Why it takes 4 hours despite for minimal change of data happened on that 4 TB LUN at Destination Site?
Q2- While doing Failback from Destination Unity to Source Unity what does means of below mentioned phrase?
All sessions will start a synchronization to the original source storage resource. The synchronization could be either delta or full synchronization depending on the replicated snapshots.
No Events found!

Hello Nadir Mukhtar,
What is the current OE on your unity? Are you failing over between SP’s or to a second unity system? Here is a link to a KB that maybe of assistance. https://dell.to/3kdsPqx

Hi,
OE 5.0.1.0.5.011
Not local replication. We are using Array to Array Async Replication with 5 Mint RPO.

Hello Nadir Mukhtar,
Just to make sure you have your Async configured like in this KB or is it configured differently?

I thinks thats more of a RecoverPoint than a Unity question
