9 (Optional) If the status of the virtual machine Placeholder VM creation error, check the placeholder
datastore mapping at the site level, right-click the virtual machine, and select Recreate Placeholder.
Modifying the Settings of a Protected Virtual Machine
You can edit the settings of a virtual machine in a protection group. Editing the settings of a virtual machine
to add or change storage devices, such as hard disks or DVD drives, can affect the protection of that virtual
machine.
If you use array-based replication, adding or changing devices on a virtual machine affects protection
depending on how you create the new device.
n
If the new device is on a replicated datastore that is not part of a protection group, the protection group
that contains the virtual machine goes into the Not Configured state. Reconfigure the protection group
to add the datastore that contains the new device to the protection group.
n
If the new device is on a replicated datastore that a different protection group protects, the protection of
the virtual machine is invalid.
n
If the new device is on an unreplicated datastore, you must replicate the datastore or remove protection
from the device.
n
If you use Storage vMotion to move a virtual machine to an unreplicated datastore, or to a replicated
datastore on an array for which Site Recovery Manager does not have a storage replication adapter
(SRA), the protection of the virtual machine is invalid. You can use Storage vMotion to move a virtual
machine to datastore that is part of another protection group.
If you add a device to a virtual machine that you protect by using vSphere Replication, you must
reconfigure vSphere Replication on the virtual machine to select the replication options for the new device.
For information about reconfiguring vSphere Replication settings, see the vSphere Replication
documentation at https://www.vmware.com/support/pubs/vsphere-replication-pubs.html.
After you modify virtual machines, you must reconfigure protection for any virtual machines that have a
status of Not Configured, Device Not Found, Unresolved Devices, or Mapping Missing. See “Apply
Inventory Mappings to All Members of a Protection Group,” on page 35 and “Configure Inventory
Mappings for an Individual Virtual Machine in a Protection Group,” on page 36.
Disabling Replication on a Protected Virtual Machine
All virtual machines in a protection group must be configured for either array-based replication or
vSphere Replication. If you disable replication on a virtual machine that is part of a protection group,
Site Recovery Manager cannot recover that virtual machine and the status for that protection group is Not
Configured.
n
If you remove protection from a virtual machine that is part of array-based replication protection
group, you must move the files of that virtual machine to an unprotected datastore. If you leave the
files of an unprotected virtual machine in a datastore that Site Recovery Manager has included in a
datastore group, recovery fails for the entire datastore group.
n
If you disable vSphere Replication on a virtual machine that you included in a protection group,
recovery fails for this virtual machine but succeeds for all of the correctly configured virtual machines
in the group. You must edit the protection group to remove the virtual machine. See “Add or Remove
Datastore Groups or Virtual Machines to or from a Protection Group,” on page 34.
