Introduction to the NOF API
NOF Verbs to Manage Specific SNAplus2 Functions
Chapter 174
• A DLC, port, and LS from SNAplus2 to the downstream computer.
For information about defining these components, see “Getting
Started”. The LS must be defined with the following parameters:
solicit_sscp_sessions = NO
dspu_services = PU_CONCENTRATION
dspu_name = the name of the PU serving the LUs on the downstream computer
pu_name = all zeros
• One or more type 0-3 LUs on the SNAplus2 node (and optionally an
LU pool containing these LUs) for communications with the host. For
information about defining LUs and LU pools, see “3270
Communications”.
You then define the LUs on the downstream computer and map these to
the LUs on the SNAplus2 node. To define the downstream LUs, use the
following verbs:
• DEFINE_DOWNSTREAM_LU,
DEFINE_DOWNSTREAM_LU_RANGE
To obtain information about the configuration or current status of
downstream LUs or about the downstream PU that serves them, use the
following verbs:
• QUERY_DOWNSTREAM_LU, QUERY_DOWNSTREAM_PU
To delete downstream LUs when they are no longer required, use the
following verbs:
• DELETE_DOWNSTREAM_LU,
DELETE_DOWNSTREAM_LU_RANGE
Managing DLUR
If the node supports DLUR (the dlur_supported parameter on the
DEFINE_NODE verb), and LUs on the SNAplus2 node will be using
DLUR to communicate with host systems, you need to define the PU on
the local SNAplus2 node that owns these LUs. This is not the same as
defining a PU for LUs that communicate directly with the host (which is
done using the DEFINE_LS verb).
To define the PU, use the following verb:
• DEFINE_INTERNAL_PU
To obtain information about the PU, use the following verb:
