system. A logical unit can be an end user, a file, a disk drive, a port, a host
group that is assigned to a port, an application, or virtual partitions (or volumes)

Logical unit numbers (LUNs) are used in SCSI protocols to differentiate disk drives
in a common SCSI target device, such as a storage system. An open-systems
host uses a LUN to access a particular LU.
