Directly or Indirectly Exporting a Disk Slice

To export a slice as a virtual disk either directly or indirectly (for example through a SVM volume), ensure that the slice does not start on the first block (block 0) of the physical disk by using the prtvtoc(1M) 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.
