Directly or Indirectly Exporting a Disk Slice

To export a slice as a virtual disk either directly or indirectly (for example through a Solaris Volume Manager volume), ensure that the slice does not start on the first block (block 0) of the physical disk by using the prtvtoc command.

If you directly or indirectly export a disk slice which starts on the first block of a physical disk, you might overwrite the partition table of the physical disk and make all partitions of that disk inaccessible.
