Solution
Make sure the vSphere Replication appliance has access to port 80 on the storage hosts.
For a list of ports that must be open for vSphere Replication, see vSphere Replication Network Ports.
Anti-virus Agent in Firewall Terminates Virtual Machine
Replication
If a virtual machine contains virus information, an anti-virus agent in the firewall might detect the virus
data and terminate the connection during replication.
Problem
When you reconfigure the replication and start a full sync, the replication stops in the same data block
with the virus information in it unless the virus data has moved on the disk. Clones of the disk fail, but
other virtual machines of the same size and configuration from the same host replicating to the same
destination datastore replicate successfully.
Solution
Remove the virus information from the replicated guest to avoid replicating virus information.
Make an exception in the anti-virus rules in the firewall to allow the replication to proceed.
Initial Full Synchronization of Virtual Machine Files to VMware
Virtual SAN Storage Is Slow
When using VMware Virtual SAN storage and configuring vSphere Replication on multiple virtual
machines, the initial full synchronization takes a long time to complete.
Problem
Configuring vSphere Replication on a large number of virtual machines simultaneously when using
vSphere Replication with Virtual SAN storage causes the initial full synchronization of the virtual machine
files to run very slowly.
Cause
Initial full synchronization operations generate heavy I/O traffic. Configuring too many replications at the
same time can overload the Virtual SAN storage.
Solution
Configure vSphere Replication in batches of a maximum of 30 virtual machines at a time.
