  2. Display the VD information: 
    /opt/MegaRAID/perccli/perccli64 /c0/vall show

      ls –l /dev/disk/by-path/
      Output similar to the following appears: Display the VD information: 
    2. In the command output, search for the line:
      pci-0000:02:00.0-scsi-0:2:X:0
      where X is the number assigned to the VD.
    3. In the line you just located, search for the sdX at the end of the line.
      The device path for the VD is /dev/sdX.
