Problem
Disk protection fails when attempting to add new disks to a protected VM that is part of a CFO (Continuous Failover) protected domain. In the example scenario below, newly added disks report initial sync for an extended period of time and then subsequently transition to a "cancelled" protection status without any replication status.
The protection status of the VM is still recoverable, but its icon turns yellow highlighting a problem with newly added disks.
Solution
When a CFO domain is configured, modifications to VM settings at the protected site must remain synchronized with the recovery site. Any issue that impedes this synchronization can generate warning reports.
Click the Details link of the VM with the yellow flagged protection status icon.
Confirm any disk(s) added to the VM at the primary site are visible on the corresponding RVM at the
recovery site.
View the list of disks under Edit Settings > Virtual Hardware.
If corresponding disk(s) cannot be found on the RVM, ensure the MSA is operational and connected. The MSA is essential to facilitate synchronization of VM settings between the RVM and the protected site VM.
After resolving any MSA issues at the recovery site, it is necessary to either:
Re-protect the virtual machines containing the newly added disks.
Or, detach and reattach the new disks to the protected VM (JSDR version 4.2.x and above).
If the DRVA is not operational, newly added disks can still appear in the RVM. However, the DRVA must be fully functional in order for data to be synchronized between the primary site and the RVM.
For Example: In a protected domain with CFO active, if the DRVA is offline and a new disk is added to the protected VM, the new disk will still be visible in the RVM. However, when a failover is initiated the contents of that disk will not actually be present in the recovered VM because the data was not synchronized with the object store.
