Cara Memeriksa Nama World Wide Port (WWPN) dari Tape Drive yang Terlampir ke host Linux

Gunakan perintah ‘cat /proc/scsi/scsi ' untuk memeriksa perangkat scsi yang terpasang. Contoh di bawah ini menunjukkan Tape Drive IBM Ultrium generasi 6 (LTO-6) yang terpasang pada sistem Linux ini.

# 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

# yum install sg3_utils

# sg_map -i -x

Perintah 'systool' menunjukkan WWPN Perangkat Tape yang terpasang ke Sistem Linux. Perintah 'systool' membutuhkan paket libsysfs dan sysfsutils untuk diinstal. Anda harus menginstalnya terlebih dahulu jika belum diinstal.

# yum install libsysfs
# yum install sysfsutils

# systool -c fc_transport -v
