To display disk label information, use the prtvtoc command.
# prtvtoc path/device-name
where device-name is the raw disk device in the patch that you want to examine.
The information varies depending on the current label of the disk. On VTOC labeled disks, information about tracks and cylinders is included. On EFI labeled disk, no track or cylinder information is provided.
