    Some details might be helpful.

    Are you trying to add a new RDM, or an exiting one, i.e. one that already has a mapping file?

    What's the LUN size that you want to use for the RDM?

    That's unusual. I've never seen such an issue myself.

    Are you trying to add the LUN as an RDM from the ESXi host 's GUI, or from vCenter Server?
    What are the build numbers of ESXi, and vCenter Server?

    It looks like this: atached screenshot

     

    Looks like problem is with LUN size, with 300GB no problem with size recognition,

     

    SOLUTION:

    add RDM disk manualy I did it by powershell api.
