To display the SCSI devices currently attached to the server

cat /proc/scsi/scsi

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST4000DM000-1F21 Rev: CC52
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi4 Channel: 00 Id: 00 Lun: 00
Vendor: Optiarc Model: DVD RW AD-7710H Rev: 1.01
Type: CD-ROM ANSI SCSI revision: 05
Host: scsi6 Channel: 00 Id: 00 Lun: 00
Vendor: LSI Model: 9750-4i DISK Rev: 5.12
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi6 Channel: 00 Id: 00 Lun: 01
Vendor: LSI Model: 9750-4i DISK Rev: 5.12

For I SCSI/SAS disks behind LSI MegaRAID controllers, the smartctl check syntax is given below. Argument megaraid,N, the integer N is the physical disk number within the MegaRAID controller.

smartctl -a -d megaraid,N /dev/sda

smartctl -a -d megaraid,4 /dev/sdb

For SATA disk, use the following syntax

smartctl -a -d sat+megaraid,N /dev/sda
