As other said, TAS use mean no VTAM definitions.
However ...it doesn't matter.
MVS console is also out of VTAM scope.
But the rules are still valid: VTAM or TAS or CONSOLxx does not use
LUNAME from OSA-ICC. All of them use devnum only to identify the
terminal/console.
How to define non-SNA terminal or console in z/OS? It is well documented
IMHO and ICC does not change anything. Just do it as for 3174-xxL
attached terminals.

Perhaps it would be better if I explain what we have. We use the BMC
suite of products including the Terminal Address Space (an alternate
access method I think they call it). Within TAS, there is a LOGON
UCB(B400) parameter. The B400 corresponds to the OSA-ICC definition.
We have a Visara 500LX box that contains a 3270 session with the same
LUNAME and CUADDR as the OSA-ICC definition (B400). We do not have a
LBUILD for B400 CUADDR anywhere in VTAM. I expected to see one
however. I assume then that the TAS is doing something under the
covers and as such VTAM doesn't need an LBUILD for B400. We do have
LBUILDs for other B4xx addresses (but they don't use TAS, they are for
TSO).

We have an OSA-ICC connection set up as a 3270 session type. The

in that definition is TERM140. The CUA is B400. We have a 3270
session
defined with the proper IP and the same LU Name of TERM140. This all
works as expected. My question is that I thought a VTAM APPL with an
LUNAME of TERM140 was required but I do not see a TERM140 defined in
VTAM
at all. I’m not a network guy. Since this is working, I assume
it’s not
required. Can someone enlighten me?
In simple words, LUNAME used in OSA-ICC session definition and
emulator - it does NOT exist in any VTAM or TCPIP configuration.
Instead, VTAM use device number (devnum), which is in turn not used
in emulator session. However OSA-ICC session ties devnum with LUNAME.
Note: the same devnum can be used by different LPARs and every LPAR
has its own console/terminal. It is not shared, just "duplicate"
devnum. However OSA-ICC use devum *and* MIF and CSS to uniquely
identify the device.
