Environment

VMware Cloud Foundation 4.x
VMware Cloud Foundation 5.x
Dell VxRail integration

Cause

The issue is caused by the decommissioning of the legacy Dell NGSSO (Next Generation Single Sign-On) authentication service in January 2026. Current versions of SDDC Manager are hardcoded to use this retired endpoint. Since the endpoint no longer exists, the server returns an HTTP 404 error, leading to an authentication failure.

Resolution

1.VXrail Bundle Preparation

• Download: Search Dell Support for "Upgrade Slim Package for" and download the major bundle.

• Rename: The filename must match the Dell download link exactly (e.g., prefixing with D1JM1_).

• Stage: Move the file to /nfs/vmware/vcf/nfs-mount/bundle/depot/local/bundles.

• Permissions: Set the file to chmod 0755 and chown vcf_lcm:vcf.

2. VVS Upload (SDDC Manager 5.0+)

• Download: Get the latest VVS file from the Dell website.

• SDDC 5.2+: Use the SDDC Manager Developer Center (API Explorer). Search for Compatibility Matrix and use the PUT method with VXRAIL_COMPAT as the source.

• SDDC 5.0 to 5.1.x: Use a cURL command (targeting localhost or the FQDN) to PUT the VVS file to the compatibility-matrices endpoint.

• Prerequisite: Ensure VmwareCompatibilityData.json exists in /nfs/vmware/vcf/nfs-mount/compatibility before uploading.

3. Partner Bundle Metadata

• Download: Retrieve vxrailPartnerBundleMetadata.json (for VCF 5.2.1+) or partnerBundleMetadata.json (for older versions) from the Broadcom portal.

• Stage: Copy the file to /home/vcf (do not place it in the NFS bundle directory).

• Permissions: Apply chown vcf_lcm:vcf and chmod 755 to the metadata file.

• Register: Navigate to the Developer Center API Explorer and use the Bundles POST method.

• Parameters: Provide the local file path and the specific VxRail version identifier (e.g., 8.0.300-28709350) in the request body.
