The MODEL_NAME parameter identifies a string used to search for an LUSEED operand in a VTAM® switched major node definition that specifies the characteristics of LUs being created dynamically.

The MODEL_NAME parameter identifies a string used to search for a match with the LU entry in the VTAM® LUGROUP definition. The LUGROUP used is selected by the LUGROUP parameter coded on the VTAM® PU. This LUGROUP parameter refers to a separate VTAM® major node (VBUILD TYPE=LUGROUP), which maps the various terminal MODEL_NAME parameters with LU characteristics (for example, DLOGMOD).

VTAM® dynamically creates an LUNAME based on the content of the LUSEED parameter, which is also coded on the VTAM® PU statement. For each LU coded with MODEL_NAME in the Communications Server configuration (.ACG) file, VTAM® matches the name with the contents of the LUGROUP definitions. When a match is found, the host creates an LUNAME based on the LUSEED parameter, replacing the ## with the hexadecimal NAU address or replacing ### with the decimal value of the NAU address received in the NMVT.

Wildcard entries can be configured in the LUGROUP definition, using the @ character. The wildcards can match any MODEL_NAME entry received. If there is only one type of LU to be defined, LUGROUP can be configured with a single wildcard, using the @ character.

MODEL_NAME is a 1- to 7-byte SNA Type A character string. Valid characters can be alphanumeric characters (A–Z, 0–9) or special characters (@, #, $).

This parameter is optional.

Note:
If a value other than all zeros (0) is specified and the host system supports SDDLU (self-defining dependent LU), the node generates an unsolicited PSID NMVT reply. If the specified string matches a VTAM® LUGROUP entry, a dynamic LU is created at the host.
