NCP volumes are NCP shares on Linux POSIX file systems such as Btrfs, ext4, and XFS. Storage Services (NSS) volumes are a special type of NCP volume.
The directory and file access are controlled with the OES trustee model for file system trustees and trustee rights. Users access NCP volume data using the Client for Open Enterprise Server software on their Windows workstations.
NOTE:UMC supports managing only those NCP shares that are mounted on NSS file systems.
