To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.

The reason why the vSAN administrator cannot find any vSAN performance statistics on the cluster summary page is that the vSAN performance service is not enabled. The vSAN performance service is a feature that collects and analyzes performance metrics and displays them in graphical charts in vCenter. The vSAN performance service must be turned on manually for each vSAN cluster, as it is not enabled by default. The other options are not correct. The integration of vRealize Operations Manager with the vSAN cluster is not required to view vSAN performance statistics, as they are available in vCenter. The administrator’s permissions on the cluster level do not affect the visibility of vSAN performance statistics, as they are accessible to any user who can view the cluster. vSAN performance statistics are not only available via CLI, as they can also be viewed in vCenter using the vSAN performance service.

Two actions that would cause some objects to be currently resyncing are:

• A change to the storage policy is applied to the objects. This action triggers a resynchronization of objects to make them compliant with the new policy settings, such as FTT, RAID level, stripe width, etc. The resynchronization process copies data from one host to another to create or update replicas or parity segments.
• A host failure occurs in the cluster. This action causes some objects to become non-compliant with their storage policy, as they lose one or more replicas or parity segments due to the host failure. The resynchronization process rebuilds the missing components on other hosts in the cluster to restore compliance and availability.References: : VMware vSphere Storage Guide, page 129 : Monitor the Resynchronization Tasks in the vSAN Cluster 1 : VMware vSAN Specialist v2 Exam Preparation Guide, page 13
