PowerStore RWX support

Reviewing the documentation:
Container Storage Modules with CSI |

For PowerStore (similar to PowerMax), I believe that volumeMode Filesystem, RWX is only supported with NFS.  Can you confirm?

the 2.15.1 documentation says: ROX, RWX with NFS ONLY
the 2.16.3 documentation removed the "with NFS only" words: "RWO, RWOP, ROX, RWX"

    In 2.16.3 for PowerStore, RWX for volume mode filesystem is supported in context of PowerStore Metro scenario. That the reason that only NFS was removed.

    what file system is required for volumemode filesystem accessmode RWX with a block device (fc, iscsi, nvmetcp) with PowerStore Metro?  what would be a functional, supported application deployment example?
