Issue/Introduction

  • When attempting to insert a Media (ISO) from an Organization VDC Catalog in VMware Cloud Director (VCD) into a Virtual Machine (VM), particularly in a Multi-Cluster vSAN Environment across vCenter servers configured in Enhanced Linked Mode (ELM), the operation may fail with an error message similar to:

     Failed to insert media "<MEDIA_NAME>" into VM "<VM_NAME>" - cannot insert Media [<MEDIA_NAME>] into VM [<VM_NAME>] because the VM's host doesn't have access to the Media's datastore <vSAN-DATASTORE_NAME>"

  • Additionally, the /opt/vmware/vcloud-director/logs/vcloud-container-info.log might show a generic exception like:

Environment

VMware Cloud Director 10.x

Cause

This issue occurs because the specific ESXi host where the Virtual Machine is running (or the host attempting to access the media from the VCD catalog) does not have access to the underlying datastore where the media file (ISO) is located.


Resolution

To resolve this issue, ensure that the shared datastore where the media files (ISOs) are stored is mounted and accessible by all ESXi hosts within your environment. 

Note: Broadcom generally recommends using dedicated shared storage solutions (e.g., NFS, iSCSI, Fibre Channel) rather than vSAN for media libraries. These dedicated solutions often provide more straightforward and consistent access control mechanisms across the entire environment, reducing the likelihood of such access-related issues.
