Usa il comando 'cat /proc/scsi/scsi ' per controllare i dispositivi scsi collegati. L'esempio seguente mostra le unità nastro IBM Ultrium generazione 6 (LTO-6) collegate a questo sistema Linux.
# cat /proc/scsi/scsi Attached devices: Host: scsi10 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: ULT3580-TD6 Rev: F9A0 Type: Sequential-Access ANSI SCSI revision: 06 Host: scsi3 Channel: 00 Id: 00 Lun: 00 Vendor: IBM Model: ULT3580-TD6 Rev: F9A0 Type: Sequential-Access ANSI SCSI revision: 06

Il comando "systool" mostra il WWPN dei dispositivi a nastro collegati al sistema Linux. Il comando 'systool' richiede l'installazione dei pacchetti libsysfs e sysfsutils. Devi prima installarli se non sono installati.
# yum install libsysfs # yum install sysfsutils
# systool -c fc_transport -v
