According to the VMware documentation [1], vSAN HCI Mesh is a feature of vSAN that enables the allocation of storage from one vSAN enabled vSphere cluster to another, allowing for the sharing of resources between clusters. This is particularly useful in scenarios such as the one described, where additional storage needs to be allocated from another vSAN enabled cluster.

PowerCLI is a command-line interface for managing VMware vSphere, vSAN and other VMware products. RVC is the Ruby vSphere Console which is an interactive command-line tool for managing vSphere, vSAN, and other VMware products. Using PowerCLI and RVC, you can run commands to identify unassociated objects and take corrective action. For example, you can use PowerCLI to list all vSAN objects and RVC to perform a check on the objects to see if they are unassociated.

If a single disk in a vSAN disk group suffers from an unrecoverable hardware failure, vSAN will mark all disks in the group with a Permanent disk loss status. This is because vSAN uses a technique called "failure domains" to ensure data availability and protect against data loss. A failure domain is a group of disks that are considered a single point of failure. If a disk in a failure domain fails, all other disks in that failure domain are also considered failed. This is to protect against further data loss in the event of a second failure in the same failure domain.

vSAN performance statistics are not available on the cluster summary page if the vSAN Performance service is not enabled. This service is responsible for collecting and displaying performance data for vSAN components such as disk groups, virtual machines and virtual disks. Without this service enabled, vSAN performance statistics will not be available on the vSphere Web Client, and the administrator will not be able to monitor the performance of the vSAN cluster.

To enable vSAN Performance service, the vSAN administrator can go to the vSphere Web Client, navigate to the vSAN cluster, click on the Configure tab, and then click on Services. Locate the vSAN Performance service, and click on the Start button.

This is explained in VMware vSAN documentation in the section "Monitoring vSAN Performance" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-admin-guide/GUID-7E8F6C98-7C0B-4D21-8F1A-F3A3A9F4F4A4.html

Roll back the vLCM configuration to the latest compliant image. After saving the configuration, all hosts in the cluster are out of compliance, so the next step is to roll back the vLCM configuration to the latest compliant image. This can be done by selecting the “Roll Back” option from the vLCM image selection menu.
