Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

• When accessing "Manual Image Settings" in vLCM, a general system error occurs: "The cluster contains payloads of unsupported solutions."
• vmware-vum-server-###.log shows as following:

Environment

vCenter Server 8.x

vCenter Server 7.x

vSphere ESXi 8.x

vSphere ESXi 7.x

Cause

vCenter Server failed to resolve the ESXi host FQDN, which blocked the vLCM eligibility check.

Resolution

To resolve this issue, ensure that bidirectional name resolution (Forward and Reverse DNS) is correctly configured between the vCenter Server and all ESXi hosts in the cluster.

1. Verify vCenter Server Resolution: Ensure the vCenter Server can resolve the Fully Qualified Domain Names (FQDNs) of all ESXi hosts in the cluster.
   1. Log in to the vCenter Server Appliance (VCSA) via SSH.
   2. Run nslookup <ESXi-Host-FQDN> to confirm resolution.
2. Verify ESXi Host Resolution: Ensure each ESXi host can resolve the vCenter Server FQDN.
   1. Log in to the ESXi host via SSH.
   2. Verify DNS configuration using esxcli network ip dns server list and check /etc/resolv.conf.
   3. Run nslookup <vCenterServer-FQDN> to confirm resolution
3. Retry vLCM Operation: Navigate back to the cluster Updates tab and attempt to access the Image settings again.
