public string canonical_device_name (string device) throws Error
return canonical device name
This utility function is useful when displaying device names to the user. It takes a number of irregular device names and returns them in a consistent format:
/dev/hdX /dev/vdX These are returned as /dev/sdX. Note this works for device names and partition names. This is approximately the reverse of the algorithm described in "BLOCK DEVICE NAMING" in guestfs(3).
/dev/mapper/VG-LV /dev/dm-N Converted to /dev/VG/LV form using lvm_canonical_lv_name.
Other strings are returned unmodified.
