How SRM Applies Mappings During Reprotect
During reprotect, SRM converts the virtual machines from the original protected site into placeholders, to
protect the recovered virtual machines that were formerly the placeholder virtual machines on the recovery
site. In most cases, the previously protected virtual machines and their devices are used during reprotect. If
you add devices to a virtual machine after the virtual machine is recovered, or if original protected virtual
machines are deleted, SRM uses mappings during reprotect.
Select Inventory Mappings
Inventory mappings provide default locations and networks for virtual machines to use when SRM creates
placeholder virtual machines on the recovery site.
Unless you intend to configure mappings individually for each member of a protection group, you should
configure inventory mappings for a site before you create protection groups.
Procedure
1 Click Sites in the left pane of the SRM interface and select the site for which to configure inventory
mappings.
2 Select a tab for a type of inventory object to configure.
3 Select an inventory object and click Configure Mapping.
4 Expand the inventory items and navigate to the resources on the recovery site to which to map the
protected site resource.
Option Action
Resource Mappings
Select a resource pool, a host, or a cluster on the recovery site. You can also
click New Resource Pool to create a resource pool on the host on the
recovery site in which to place the recovered virtual machines. You cannot
create a new resource pool on a cluster.
Folder Mappings
Select a datacenter or virtual machine folder on the recovery site. You can
also click New Folder to create a virtual machine folder on the host on the
recovery site in which to place the recovered virtual machines. You cannot
create a new folder on a cluster.
Network Mappings
Select a network on the recovery site to use to connect the recovered
virtual machines.
The selected resource appears in the Recovery Site Resource column. The path to the resource relative
to the root of the vCenter Server on the recovery site appears in the Recovery Site Path column.
5 Repeat Step 2 through Step 4 for all resource types for which to establish mappings.
About Placeholder Datastores
For every virtual machine in a protection group, SRM creates a placeholder virtual machine at the recovery
site. You must identify a datastore on the recovery site in which SRM can store the placeholder virtual
machines.
After you select the datastore to contain the placeholder virtual machines, SRM reserves a place for
protected virtual machines in the inventory on the recovery site. SRM creates a set of virtual machine files
on the specified datastore at the recovery site and uses that subset to register the placeholder virtual
machine with vCenter Server on the recovery site.
To enable planned migration and reprotect, you must select placeholder datastores at both sites.
Placeholder datastores must meet certain criteria.
n
For clusters, the placeholder datastores must be visible to all of the hosts in the cluster.
