```

Start by tracing the Azure ARM deployment flow around the CreateOrUpdate polling failure shown in the logs, especially the DiskServiceInternalError response. Determine how transient deployment failures are handled and define completion as a retry path that avoids immediately failing for this Azure internal error, with regression coverage if the existing tests support it.
