Application Quiescing Changes to File System Quiescing During
vMotion to an Older Host
vSphere Replication can create an application quiesced replica for virtual machines with Windows Server
2008 and Windows 8 guest operating systems running on an ESXi 5.1 or newer host.
Problem
The ESXi 5.1 or newer host is in a cluster with hosts from older versions and you use vMotion to move
the replicated virtual machine to an older host. vSphere Replication then creates a file system quiesced
replica.
Cause
A mix of ESXi 5.1 (or newer) and older hosts in the cluster creates a file system quiesced replica during
vMotion to an older host. The process should instead create an application quiesced replica.
Solution
Make sure that all hosts in the cluster are running ESXi 5.1 or newer before you use vMotion to move a
Windows Server 2008 and Windows 8 virtual machine with application quiescing.
Configuring Replication Fails for Virtual Machines with Two Disks
on Dierent Datastores
If you try to configure vSphere Replication on a virtual machine that includes two disks that are contained
in different datastores, the configuration fails.
Problem
Configuration of replication fails with the following error:
Multiple source disks with device keys device_keys point to the same destination datastore and file
path disk_path.
Cause
This problem occurs because vSphere Replication does not generate a unique datastore path or file
name for the destination virtual disk.
Solution
If you select different datastores for the VMDK files on the protected site, you must also select different
datastores for the target VMDK files on the secondary site.
Alternatively, you can create a unique datastore path by placing the VMDK files in separate folders on a
single target datastore on the secondary site.
