Description: Shows the current number of units in the stack.
What is rlPhdNumberOfUnits?
This read-only INTEGER reports how many physical units are currently active members of the stack. An admin monitoring stack health can watch this value drop unexpectedly as an early sign that a unit has failed, been disconnected, or dropped out of the stack. For example, if this value falls from 4 to 3 without any planned maintenance, the admin knows one unit has gone offline or lost its stacking link and should investigate immediately.
