In the reprotect process using storage policy protection, Site Recovery Manager reverses the direction of replication and protects the virtual machines that are associated with the relevant storage policies on what was previously the recovery site. Site Recovery Manager reestablishes vSphere entity protection and monitoring on the new protected site.
Reversing the replication of a storage policy protection group is the same as reversing the replication of an array-based replication protection group because it only affects the underlying storage. When you perform reprotect on a recovery plan that includes a storage policy protection group, the replication technology that your storage arrays provide reverses the replication of all of the consistency groups that are associated with the storage policies that the protection group contains.
If the storage arrays fail to reverse replication for any consistency groups in the protection group, the recovery plan goes into the Incomplete Reprotect state. In this state, you must resolve the storage issues and run reprotect again. Rerunning reprotect on a storage policy protection group only affects the direction of replication of consistency groups for which a previous reprotect operation did not complete successfully.
When the storage arrays have reversed the direction of replication, Site Recovery Manager reestablishes vSphere entity protection and monitoring. The conditions for reestablishment of vSphere entity protection and monitoring during reprotect are less strict than the conditions for establishing vSphere entity protection and monitoring during the creation of a storage policy protection group:
- Site Recovery Manager checks the storage policies on the new protected site for compliance. If storage policies on the new protected site are non-compliant, reprotect does not fail but Site Recovery Manager cannot protect the virtual machines that are associated with that storage policy. For information about compliance, see Prerequisites for Storage Policy Protection Groups and Limitations of Storage Policy Protection Groups.
- Site Recovery Manager restarts vSphere entity monitoring on the new protected site.
- Site Recovery Manager starts protecting all compliant virtual machines. This might not be the same set of virtual machines as was recovered when you ran the recovery plan initially because you or another user might have associated more virtual machines with the storage policy on the new protected site. Reprotect does not fail if Site Recovery Manager fails to protect a virtual machine on the new protected site.
- The storage policy protection group is ready for recovery from the new protected site to the new recovery site.
