An administrator has successfully configured a Metro Availability protection domain. After a few days, the following NCC warning is raised:

What is the first action the administrator must take to resolve the issue?

  • A Run command ncli pd ls metro-avail-true |egnep “Protection Domain|Stretch|Role” |grep -B2 "ACTIVE" | grep “Protection Domain”.
  • B Run command ncc health_checks metro_availability_checks data_locality_check --cvm_list=X.X.X.20.
  • C Migrate the VM to its primary site and set appropriate rules for DRS and affinity.
  • D Use "must" affinity rules to avoid automated VM migration to the standby datastore.
Explanation

In a Nutanix Metro Availability deployment, a data_locality_check warning indicating a VM is reading and writing across the metro link from a remote cluster means the VM's compute is currently running at a site opposite from where the active copy of its data resides; because Metro Availability resolves I/O against the local copy for optimal performance while synchronously mirroring to the standby site, the corrective action is to migrate the VM back onto a host at the site holding its data and then configure appropriate DRS/affinity rules so future placement stays aligned with the protection domain's active site.
