Hello, all.

We have two datacenters with one Unity 480F and several ESXi hosts in each.

In primary DC Unity presents thin volumes to this DC's hosts. Also for these volumes a synchronous replication is configured to secondary DC. There replicas are presented to local ESXi hosts. OK.

Then we do SCSI UNMAP operation on primary DC hosts. Free space on volumes is grow. OK. But what about their replicas size? UNMAP results will be transfer automatically to replicas by replication process or not?
