scsi_id not returning any output in a VM on VMware ESX

  1. scsi_id not returning result:

    scsi_id -g -u -d /dev/sdb
    No Result

  2. Start the vSphere Client, and log in to a vCenter Server.
  3.  Select Virtual Machines for which you want to retrieve disk unique id. I need this attribute for udev rules to prepare disks for ASM, for example.
  4.  Right-click the virtual machine for which you are enabling the disk UUID attribute, and select Power > Power Off.
    The virtual machine powers off.
  5. Right-click the virtual machine, and click Edit Settings.
  6. Click the Options tab, and select the General entry in the settings column.
  7. Click Configuration Parameters.
    The Configuration Paramters window appears.
  8. Click Add Row.
  9. In the Name column, enter disk.EnableUUID
  10. In the Value column, enter TRUE.
  11. Click OK and click Save.
  12. Power on the virtual machine.
  13. Now, it returns id:

    scsi_id -g -u -d /dev/sdb
