LIBSCSI(8)

NAME
libscsi - SCSI device library

DESCRIPTION

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)).

PERMISSIONS

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.
