LIBSCSI(8)LIBSCSI(8)NAMElibscsi - SCSI device library
The SCSI device library is a private set of interfaces that NetWorker
uses to communicate with SCSI devices.
Important: SCSI devices are named independently of the platform.
There are several functions in this library. The name of a SCSI device
is identified as a combination of bus, target, and logical unit number
(LUN) (b.t.l), where b is the logical scsi bus, t is the SCSI target,
and l is the SCSI LUN on that target. Do not assume that a logical SCSI
bus number is related to any specific platform or hardware bus number.
Rather, a logical SCSI bus number is a dense positive integer address
space that is consistent as long as the hardware configuration of the
system remains the same. Target and LUN information is based upon the
attached SCSI peripheral devices and their settings. Some platforms
enable dynamic addition and removal of SCSI devices, but may require
flushing of cached device information (see lrescan(8)).
Typically, if a device has no system driver, system privileges are not
required for users to send commands to this device. If a device has a
system driver (for example, a tape drive), then system privileges are
required in order to send a command to these devices.
