When running NCC on one of the customers cluster, the following output is generated...
FAIL: Remote site: HQ-NTNXNumber of vstores mapped for the local site on the remote site are not same.Refer to KB 3335 (http://portal.nutanix.com/kb/3335) for details on remote_site_config_check or Recheck with: ncc health_checks data_protection_checks remote_site_checks remote_site_config_check
Why is it so important to have the same number of mappings? When we are replication from site A to site B, we can use different mappings than when replication is executed from site B to site A.

The general thought here is that if you have mappings that occur at source that dont occur at target, reverse failback for things might be affected. There could be other reasons that I'm not thinking of off the top of my head.
