Check dmesg

dmesg should output something like:

  Vendor: WDIGTL Model: ENTERPRISE Rev: 1.91
  Type: Direct-Access ANSI SCSI
revision: 02
  Vendor: SEAGATE Model: ST32155W Rev: 0528
  Type: Direct-Access ANSI SCSI
revision: 02
  Vendor: COMPAQPC Model: ST34371N Rev: 0472

  Vendor: TEAC Model: CD-ROM CD-516S Rev: 1.0D
  Type: CD-ROM ANSI SCSI

Detected scsi disk sda at scsi0, channel 0, id 0, lun 0
Detected scsi disk sdb at scsi0, channel 0, id 1, lun 0
Detected scsi disk sdc at scsi1, channel 0, id 0, lun 0
SCSI device sda: 8515173 512-byte hdwr sectors (4360 MB)
Partition check:
sda: sda1 sda2 sda3
SCSI device sdb: 4197405 512-byte hdwr sectors (2149 MB)
sdb: sdb1
SCSI device sdc: 8386000 512-byte hdwr sectors (4294 MB)
sdc: unknown partition table

If you forget channel, HBA, or ID your device is on look in
/proc/scsi/scsi which should contain something like:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: WDIGTL Model: ENTERPRISE Rev: 1.91
  Type: Direct-Access ANSI SCSI
revision: 02
Host: scsi0 Channel: 00 Id: 01 Lun: 00
  Vendor: SEAGATE Model: ST32155W Rev: 0528
  Type: Direct-Access ANSI SCSI
revision: 02
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: COMPAQPC Model: ST34371N Rev: 0472
  Type: Direct-Access ANSI SCSI
revision: 02
Host: scsi1 Channel: 00 Id: 05 Lun: 00
  Vendor: TEAC Model: CD-ROM CD-516S Rev: 1.0D
  Type: CD-ROM ANSI SCSI
revision: 02

All you have to do is match the HBA, channel, id, lun
tuple with the dmesg entry "Detected scsi disk..."
