Physical parent (virtual pairing only) delete rules

The following list describes the delete rules for a physical parent with virtual pairing only.

• PHYSICAL/LOGICAL/VIRTUAL is meaningless.
• BIDIRECTIONAL VIRTUAL means a physical parent is automatically deleted along its physical path when it is no longer involved in a logical relationship. A physical parent is no longer involved in a logical relationship when:
  • It has no logical children pointing to it (its logical child counter is zero, if it has one)
  • It points to no logical children (all of its logical child pointers are zero, if it has any)
  • It has no physical children that are also real logical children
