Gotcha - primary means that at cluster startup, primary will always
be the live node and secondary will always be the backup director.

OK, so let's itemize the available three letter acronyms that are easy
to pronounce and end in IP:
BIP
FIP
GIP
HIP
JIP
KIP
LIP
MIP
NIP
PIP
QIP
SIP
TIP
WIP
YIP
ZIP
So, can we think of something that begins with any of the following letters
that adequately describes a real director IP?
B, F, G, H, J, K, L, M, N, P, Q, S, T, W, Y, Z
PIP and SIP are OK, but I am not enthusiastic about having two TLAs for
essentially the same function.
