How to light disk locate light on current versions

We have an ODA X5-2 running 19.10 and have 2 disks in predictive failure mode. In the past we have used the oakcli locate disk command to turn the disk locate light on so that our Data Center staff will be sure to remove the correct disk and prevent problems and errors. oakcli is no longer around and the current software does not have this feature (although documentation and bugs filed indicate it should be added).

Documentation on disk numbering is sometimes unclear and the system numbers the disks from 0 but diagrams number from 1 so that is room for error. How do you handle this situation the best these days?
