HP-UX SNAplus2 R7 NOF Programmer's Guide

Introduction to the NOF API
NOF Verbs to Manage Specific SNAplus2 Functions
To delete a node and the LUs associated with it or to delete LUs from a node entry, use the following verb:
• DELETE_ADJACENT_LEN_NODE
If the local node is an end node or network node communicating with a LEN node, or if the local node is the
network node serving a LEN node, you need to set up directory entries for the LEN node and its LUs, using the
verbs described above. For communications with other node types, you do not need to set up directory entries
because the node will locate these resources dynamically as required (and add them to the directory so that they
can be used again).
However, you may want to set up entries for particular nodes or LUs so that the local node can communicate with
these resources without having to search for them. Because setting up entries for particular nodes or LUs overrides
the normal APPN resource location process, you can have problems at this node or at other nodes in the network
if the definitions are not correct. Do not define explicit entries for resources at other nodes unless you are sure that
the definitions are correct.
To define an individual node, LU, or wildcard entry for a range of LUs, use the following verb:
• DEFINE_DIRECTORY_ENTRY
To delete an individual node, LU, or wildcard entry from the directory, use the following verb:
• DELETE_DIRECTORY_ENTRY
Delete only directory entries that were explicitly defined using the verbs described previously (these entries return
an entry type of HOME on the QUERY_DIRECTORY_ENTRY verb). Do not use this verb to delete cached entries
(entries that have been set up dynamically as a result of network searches).
1.5.16 Querying the Network Topology
To obtain information (on a network node) about adjacent network nodes, use the following verb:
• QUERY_ADJACENT_NN
To obtain information about the TGs to adjacent network nodes, use the following verb:
• QUERY_LOCAL_TOPOLOGY
To obtain information (on a network node) about network nodes and virtual routing nodes (VRNs) in the network,
or about the TGs to these nodes, use the following verbs:
• QUERY_NN_TOPOLOGY_NODE, QUERY_NN_TOPOLOGY_TG
To obtain statistical information (on a network node) about the use of entries in the local node’s topology database,
use the following verb:
• QUERY_NN_TOPOLOGY_STATS
1.5.17 Checking the Communications Path to a Remote LU
To check that a particular target LU can be accessed (that the node owning the LU is active and that there is a
communications path to the LU), use the following verb:
• APING
1.5.18 Managing Servers on the SNAplus2 LAN
To obtain a list of servers (nodes) on the SNAplus2 LAN, use the following verb:
• QUERY_NODE_ALL
To obtain detailed information about a particular node, use the following verb:
