[VMC on AWS] SDR appliance does not have access to the target datastore during HCX OSAM migration

Products

• VMware HCX
• VMware Cloud on AWS

Issue/Introduction

You may encounter the error message 'Unable to migrate VM as the SDR appliance does not have access to the target datastore' when attempting an HCX OSAM migration to a cluster.

Environment

HCX
VMC

Cause

This issue occurs when the environment contains multiple clusters in VMC. If HCX was initially deployed with a single cluster and an additional cluster is added, a separate Compute Profile must be created to allow the cluster networks (management/vMotion) to be independent.

Resolution

Create a separate Compute Profile for the additional cluster.

Workaround:
As a workaround, you can use Cluster 1 as the destination for the migration, and then perform a vMotion to the other cluster once the OSAM process is complete.

Additional Information

This is the expected behavior, as creating a separate Compute Profile for each cluster allows for dedicated IX/OSAM appliances, which are managed through a separate Service Mesh.
For more information, please refer to the 'Getting Started with VMware HCX' guide on Techdocs Broadcom, ensuring you select the version that matches your current deployment.
