To view the resynchronizing metrics, the vSAN administrator should open the Backend performance category. This category shows the performance of vSAN data components, such as read/write latency, IOPS, throughput, congestion, and resync traffic. The other categories are not relevant for this task. Disks shows the performance of physical disks in the cluster, Host Network shows the network performance of vSAN hosts, and Resvnc Latency shows the latency of resynchronization operations.

To avoid storage policy non-compliance, the vSAN maintenance mode option that should be used is Full data migration. This option evacuates all data from the host to other hosts in the cluster and maintains the current object compliance state. This means that the VM objects will have access to all their replicas and will be compliant with their assigned storage policies. The other options might result in storage policy non-compliance, as they do not guarantee full data redundancy or policy adherence. Ensure accessibility only migrates the components that are essential for running the VMs, but might not have access to all their replicas. Partial maintenance mode is not a valid option for vSAN clusters. No data migration does not evacuate any data from the host and might result in VM unavailability or data loss.

To upgrade multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters, the administrator can upgrade two witness node types: appliance witness node and nested witness node. An appliance witness node is a virtual ESXi host that runs on a physical ESXi host and contains the witness components of VM objects stored in the vSAN cluster. A nested witness node is a virtual ESXi host that runs on another virtual ESXi host and contains the witness components of VM objects stored in the vSAN cluster. Both types of witness nodes can be managed by vLCM as independent nodes since vSphere 7.0 Update 3, as long as they are version 7.0 Update 2 or later. The other options are not correct. A shared witness node is a witness node that serves multiple vSAN clusters, which is not supported by vLCM. A dedicated witness node is a witness node that serves only one vSAN cluster, which is not a specific type of witness node. A physical witness node is aphysical ESXi host that contains the witness components of VM objects stored in the vSAN cluster, which cannot be upgraded by vLCM.
