6.1

Protection Groups
IMPORTANT Protection groups for stretched storage must be created as storage policy protection groups. You
must create and use storage profiles to protect and recover stretched storage devices.
n
Protection groups with stretched devices must have a preferred direction from the protected site to the
recovery site. The preferred direction must match the site preference that the array maintains for the
corresponding devices. If the array supports site preference, then the protected site must have the site
preference.
n
Stretched and nonstretched virtual machines and consistency groups can be in the same protection
groups and the same recovery plan.
n
The stretched virtual machines must be on a stretched datastore and must be powered on at the
protected site.
n
You cannot create two protection groups in opposite directions by using the same stretched device pair,
but you can place virtual machines on the stretched devices at the recovery site that correspond to
protected devices at the protected site. You cannot protect these virtual machines, but they are
automatically protected during the reprotect process.
Planned Migration
n
The Run Recovery Plan wizard has an option to use Cross vCenter Server vMotion to perform a
planned migration. If the option is selected, Cross vCenter Server vMotion is used for all protected,
powered-on virtual machines on the stretched storage at the protected site. If the option is not selected,
the regular recovery workflow is used for replicated LUNs, including stretched storage.
n
If Cross vCenter Server vMotion fails for any reason, the recovery plan stops at the "Migrating VMs"
step and does not continue. If you cannot resolve the problem that is preventing Site Recovery Manager
from using Cross vCenter Server vMotion, rerun the recovery plan with the vSphere vMotion option
turned off. The migration can then use the regular recovery workflow for replicated LUNs.
n
During the deactivate step the stretched devices stay mounted at the protected site even if vMotion is
not used. Site Recovery Manager ignores non-protected replica virtual machines on the stretched
devices at the protected site and does not unregister them.
Test Recovery
n
Test recovery is performed by using the regular test recovery workflow for replicated devices,
including stretched devices. vMotion compatibility checks are performed for each virtual machine on
the stretched devices.
n
If the array does not support creating read-write snapshots for stretched devices,
Site Recovery Manager does not allow you to perform a test recovery for these devices.
Cross vCenter Server vMotion
Cross vCenter Server vMotion is not supported for migration from a vSphere Distributed Switch port group
to a standard switch network. In this instance, attempting to Cross vCenter Server vMotion a virtual
machine results in these error messages.
n
Unable to find a host in the cluster <cluster-name> that is compatible with the
Cross vCenter Server vMotion of the virtual machine <vm-name> from the protection group <PG-
name>.
