Purpose

The DISPLAY MAJNODES (major nodes) command displays the status of all active major nodes in the domain.

This command displays the status of all active major nodes, which include the following major node types:

Adjacent CP
Application program
Cross-domain resource manager (CDRM); in a multiple-domain network
Channel-attachment
Cross-domain resource (CDRSC); in a multiple-domain network (including independent logical units)
Dynamic XCF local SNA major node (ISTLSXCF)
External communication adapter (XCA)
Local SNA
Local non-SNA
LUGROUP
Model
NCP
Rapid transport protocol (ISTRTPMN)
Switched
Transport resource list

Note: NCP major nodes, which are type 4 physical units, are listed in the display as PU T4/5 major nodes. The VTAM® host physical unit, which is a type 5 physical unit, is listed in the display as a PU T4/5 major node. Channel-attachment major nodes are listed in the display as CA major nodes.

Operands

MAX

Specifies the maximum number of active major nodes that VTAM displays for this command.

MAX=*: Specifies that the value of the DSPLYMAX start option is used to limit the display output.
MAX=number_of_resources: Specifies the number of active major nodes that VTAM displays for this command. The valid range is 1–value of DSPLYMAX. The default is the value specified for the DSPLYDEF start option.
Specifying MAX limits the display output. VTAM searches only for the number of instances that you have specified. When that number is found, VTAM does not search any further. This saves processing time for the command and gives you control over the amount of display output generated by the command. If fewer active major nodes are found than you have specified on MAX, VTAM displays only the active major nodes that are found.

Resulting display

The resulting display gives the name, type, and status of each known major node.

Displaying major nodes: limiting output to two resources:

d net,majnodes,max=2
IST097I DISPLAY ACCEPTED
IST350I DISPLAY TYPE = MAJOR NODES
IST089I VTAMSEG  TYPE = APPL SEGMENT     , ACTIV
IST089I VTAMSG2  TYPE = APPL SEGMENT     , ACTIV
IST1315I DISPLAY TRUNCATED AT MAX = 2
IST1454I 2 RESOURCE(S) DISPLAYED
