Resolution

This is a known issue affecting VMware Cloud Foundation on VxRail. There is currently no resolution.

Workaround:
Use the following steps to workaround this issue:

1. End the current bringup. This will necessitate re-imaging the ESXi hosts so that they can be used in a new bringup attempt. Ensure that the  Dell EMC RASR (Rapid Appliance Self Recovery) process is used.
2. In the Cloud Builder UI, upload the deployment parameters spreadsheet but do not click the Validate button.
3. SSH to the Cloud Builder VM as the admin user and then issue the su - command to switch to the root user.
4. Open the /tmp/sddcspec-<UUID>.json file with a text editor.
5. Change the value of "subnet" field under "HostSpecs" -> "ipAddressPrivate"

Note: There is one "subnet" field for each ESXi host in the file. The same change will need to be made for each host.

6. Save and close the file.
7. Use a file transfer utility to copy the /tmp/sddcspec-<UUID>.json file from the Cloud Builder VM to the local system.
8. In the Cloud Builder UI, upload the modified json file that was copied in Step 7.
9. Proceed with validation and bringup as usual.
