sg3_utils-1.48

sg3_utils の概要

The sg3_utils package contains low level utilities for devices that use a SCSI command set. Apart from SCSI parallel interface (SPI) devices, the SCSI command set is used by ATAPI devices (CD/DVDs and tapes), USB mass storage devices, Fibre Channel disks, IEEE 1394 storage devices (that use the "SBP" protocol), SAS, iSCSI and FCoE devices (amongst others).
