When you run reprotect on a recovery plan that contains vSphere Replication protection groups, the operation times out with an error.
Reprotect operations on recovery plans that contain vSphere Replication protection groups fail with the error Operation timed out: 7200 seconds VR synchronization failed for VRM group <Unavailable>. Operation timed out: 7200 seconds.
When you run reprotect, Site Recovery Manager performs an online sync for the vSphere Replication protection group, which might cause the operation to timeout. The default timeout value is 2 hours and corresponds to a working synchronization timeout of 4 hours.
Increase the synchronizationTimeout timeout value in Advanced Settings. See Change vSphere Replication Settings.
