vSAN-related options are missing under both the Monitor and Configure tabs for vSAN-enabled clusters in the vSphere Client

Products

• VMware vCenter Server

Issue/Introduction

Symptoms:

• vSAN options not displayed across all clusters on a specific vCenter server.

• Restarting the vmware-vsan-health service does not resolve the issue.

• From vsphere_client_virgo.log, we see the below error:

• After updating the custom certificates on vSAN ESXi host and encountered with this error: "vSAN ESXi host will not exit maintenance mode with error SSL Exception: Verification parameters: PeerThumbprint."

Environment

VMware vCenter Server 8.x

Cause

• vSphere with vSAN using custom certificates.
• This is because the vsanmgmtd service has not been restarted and is caching the old certificate.

Resolution

Reboot the ESXi host and restarting the vCenter services resolved the issue.

Steps to restart the vCenter services:
1. Connect to the vCenter Server Appliance via SSH as root. 
2. To stop all services, use the command: service-control --stop --all 
3. To start all services, use the command: service-control --start --all
