What to read next

OVF Package Is Invalid and Cannot Be Deployed
When you attempt to deploy OVF for the vSphere Replication appliance, an OVF package error might occur.
vSphere Replication Service Fails with Unresolved Host Error
If the address of vCenter Server is not set to a fully qualified domain name (FQDN) or to a literal address, the vSphere Replication service can stop unexpectedly or fail to start after a reboot.
Error Recovering Virtual Machine in a Single vCenter Server Instance
You might receive an error message when you are recovering a virtual machine with the same name in a single vCenter Server instance.
vSphere Replication RPO Violations
You might encounter RPO violations even if vSphere Replication is running successfully at the recovery site.
vSphere Replication Appliance Extension Cannot Be Deleted
If you delete the vSphere Replication appliance virtual machine, the VRMS Appliance Management Interface is not available to delete the appliance extension that still exists in vCenter Server.
vSphere Replication Does Not Start After Moving the Host
If you move the ESXi Server on which the vSphere Replication appliance runs to the inventory of another vCenter Server instance, vSphere Replication operations are not available. If you reinstall vCenter Server, vSphere Replication operations are also unavailable.
Unexpected vSphere Replication Failure Results in a Generic Error
vSphere Replication includes a generic error message in the logs when certain unexpected failures occur.
Reconnecting Sites Fails If One of the vCenter Server Instances Has Changed Its IP Address
When the vCenter Server address of one site changes, the connection status between two sites is displayed as Not connected and you cannot reconnect the sites.
vSphere Replication Server Registration Takes Several Minutes
vSphere Replication server registration might take a long time depending on the number of hosts in the vCenter Server inventory.
Generating Support Bundles Disrupts vSphere Replication Recovery
If you generate a vSphere Replication log bundle and at the same time attempt to run a recovery, the recovery might fail.
vSphere Replication Operations Take a Long Time to Complete
Some vSphere Replication operations might take a long time to complete during a heavy load.
vSphere Replication Operations Fail with Authentication Error
An error message appears when you try to configure a replication between two sites, though the sites are paired.
vSphere Replication Does Not Display Incoming Replications When the Source Site Is Inaccessible
The list of incoming replications between two remote sites fails to populate when the connection to the local site is refused.
vSphere Replication Is Inaccessible After Changing vCenter Server Certificate
If you change the SSL certificate of vCenter Server, you cannot access vSphere Replication.
vSphere Replication Cannot Establish a Connection to the Hosts
Replications fail because vSphere Replication cannot connect to the hosts.
Anti-Virus Agent in Firewall Stops Virtual Machine Replication
If a virtual machine contains virus information, an anti-virus agent in the firewall might detect the virus data and stop the connection during replication.
Initial Full Synchronization of Virtual Machine Files to VMware vSAN Storage Is Slow
When using VMware vSAN storage and configuring vSphere Replication on multiple virtual machines, the initial full synchronization takes a long time to complete.
Update the Child Replica Disks When Changing the Storage Policy for a vSAN Target Datastore
When you change a target storage policy and the target datastore is vSAN, the base disk storage policy is updated, but the child disk storage policy still refers to the previous storage policy.
Configuring Replication Fails Because Another Virtual Machine Has the Same Instance UUID
You cannot configure a replication because another virtual machine already exists at the target site.
vSphere Replication Operations Run Slowly as the Number of Replications Increases
As you increase the number of virtual machines that you replicate, vSphere Replication operations can run more slowly.
Unable to Establish an SSH Connection to the vSphere Replication Appliance
SSH connections to the vSphere Replication appliance are deactivated.
The Replication Pauses When You Add a New Disk to the Source VM
The replication pauses when you add a new disk to the source virtual machine.
The vSphere Replication Appliance Root File System Switches to Read-Only Mode and Login Fails
The vSphere Replication appliance root file system switches to read-only mode, and you cannot log in.
Configuration of an Encrypted VM Fails with an Error
When you try to configure a replication for an encrypted virtual machine, the process fails with an error.
Reprotect Failures on Overloaded Datastores
Reversing replications at large scale during the reprotect operation might fail due to issues caused by an overloaded datastore.
Reconfigure replication process fails with an error after a long time
Reconfiguring a replication with a target ESXi host that has a disallowed tag, fails with an error.
Configuring a replication for a VM with physical mode RDM disk fails with an error
You cannot configure a replication for a virtual machine with physical mode RDM disk even if the disk is excluded from replication .
You cannot use custom defined users and roles with vSphere Replication
You cannot configure a replication with a custom user, even if the custom user is assigned all required VRM privileges on both sites.
VMs that are located in the target folder are overwritten during recovery with vSphere Replication
If the target folder contains a registered virtual machine with the same name as the replicated virtual machine, the registered virtual machine is overwritten during the recovery.
Generating a support bundle fails
If you try to generate a vSphere Replication support bundle, the process fails.
You cannot configure new replications with network encryption
When you try to configure new replications with network encryption, the network encryption option is not active.
Replications with network encryption appear in Not Active state
Existing replications that were configured with network encryption enter Not Active state.
You cannot use network encryption for vSphere Replication
When you try to configure network encryption for a replication, the option in the Configure replication wizard is inactive.
