Before we moved to parallel sysplex in the 90s, we had only a few real-hardware
CTC devices with ragamuffin unit addresses assigned haphazardly over the years.

over TCPIP is also not new, probably 10+ years.

I agree with Radoslaw that an elaborate CTC naming convention might be overkill
for many shops. OTOH when we introduced sysplex in the mid-90s, we went from a
handful of single-purpose LPARs across four CECs to multisystem plexes. We
started with no CTCs to speak of, but XCF wants CTCs as
, but as noted above, adding one volume to
production is actually a three-fold increase in addresses.
The advantage of any CTC naming scheme over just assigning random addresses is
that a CTC can be fully identified by address alone: CEC, LPAR, and usage such
as XCF vs. VTAM. The stories we heard
single CPC.
The same for LPARs - do you really need more than 16 in CTC? Much more?
How many bits?
Of course it's also possible to define CTC with no reasonable convention
at all. The only things which are really checked are CUADD number and UA
for device. However all the devices
