Hans-G?nter@24865 1 The lsscsi command lists information about SCSI devices in Linux.
Hans-G?nter@24865 2 Using SCSI terminology, lsscsi lists SCSI logical units
Hans-G?nter@24865 3 (or SCSI targets when the '--transport' option is given).
Hans-G?nter@24865 4 The default action is to produce one line of output for each SCSI device
Hans-G?nter@24865 5 currently attached to the system.
Hans-G?nter@24865 6 In version 0.30 of this utility, support was added to list NVMe namespaces
Hans-G?nter@24865 7 (under SCSI devices(LUs)) and NVMe controllers (under SCSI hosts).
Hans-G?nter@24865 8
Hans-G?nter@24865 9 When the '--hosts' option is given the lsscsi command lists information
Hans-G?nter@24865 10 about SCSI hosts attached to the system.
Hans-G?nter@24865 11 A host can be actual hardware (sometimes referred to as Host Bus Adapters
Hans-G?nter@24865 12 (HBAs)) or virtual.
Hans-G?nter@24865 13 An example of a virtual host is USB mass storage that bridges between USB
Hans-G?nter@24865 14 and the SCSI subsystem. In SCSI parlance, a host is referred to as an
Hans-G?nter@24865 15 SCSI initiator.
Hans-G?nter@24865 16
Hans-G?nter@24865 17 The lsscsi command scans the sysfs pseudo file system that was introduced
Hans-G?nter@24865 18 in the 2.6 Linux kernel series.
Hans-G?nter@24865 19 Since most users have permissions to read sysfs (usually mounted at /sys )
Hans-G?nter@24865 20 then meta information can be found on some or all SCSI devices without a
Hans-G?nter@24865 21 user needing elevated permissions to access special files (e.g. /dev/sda ).
Hans-G?nter@24865 22 The lsscsi command can also show the relationship between a device's
Hans-G?nter@24865 23 primary node name, its SCSI generic (sg) node name and its kernel name.
Hans-G?nter@24865 24
Hans-G?nter@24865 25 The lsscsi command works in the 2.6, 3, 4 and 5 Linux kernel series.
