Linux / Unix Command: scsi_info
Command Library


scsi_info - SCSI device description tool  


scsi_info device  


Scsi_info opens the specified SCSI device file, and retrieves its actual SCSI address parameters. It also looks up the device in /proc/scsi/scsi and retrieves the device's vendor information, if available. Its output is a pair of Bourne-style shell commands to define the SCSI_ID and MODEL variables based on this information. The SCSI_ID variable has three comma-separated fields: the SCSI channel number, the device ID, and the logical unit number. In most cases, the channel and logical unit will be 0.

The reason for the existence of this utility lies in the peculiar method for assigning minor device numbers to Linux SCSI devices. Devices are numbered based on the order in which they are detected, irrespective of their device addresses. This tool automatically converts these arbitrary device assignments back to the user-configured addresses.  

Important: Use the man command (% man) to see how a command is used on your particular computer.
