     1.4 +The lsscsi command lists information about SCSI devices in Linux.
     1.5 +Using SCSI terminology, lsscsi lists SCSI logical units
     1.6 +(or SCSI targets when the '--transport' option is given).
     1.7 +The default action is to produce one line of output for each SCSI device
     1.8 +currently attached to the system.
     1.9 +In version 0.30 of this utility, support was added to list NVMe namespaces
    1.10 +(under SCSI devices(LUs)) and NVMe controllers (under SCSI hosts).
    1.11 +
    1.12 +When the '--hosts' option is given the lsscsi command lists information
    1.13 +about SCSI hosts attached to the system.
    1.14 +A host can be actual hardware (sometimes referred to as Host Bus Adapters
    1.15 +(HBAs)) or virtual.
    1.16 +An example of a virtual host is USB mass storage that bridges between USB
    1.17 +and the SCSI subsystem. In SCSI parlance, a host is referred to as an
    1.18 +SCSI initiator.
    1.19 +
    1.20 +The lsscsi command scans the sysfs pseudo file system that was introduced
    1.21 +in the 2.6 Linux kernel series.
    1.22 +Since most users have permissions to read sysfs (usually mounted at /sys )
    1.23 +then meta information can be found on some or all SCSI devices without a
    1.24 +user needing elevated permissions to access special files (e.g. /dev/sda ).
    1.25 +The lsscsi command can also show the relationship between a device's
    1.26 +primary node name, its SCSI generic (sg) node name and its kernel name.
    1.27 +
    1.28 +The lsscsi command works in the 2.6, 3, 4 and 5 Linux kernel series.
