HP-UX SNAplus2 R7 Administration Guide

Defining Connectivity Components
Defining DLUR PUs
To provide passthrough DLUR services to a downstream node, you must first configure (on the local node) the
PU name associated with the downstream node. This value must match the PU name that is configured for the
downstream node on the host computer.
To configure a DLUR PU, use one of the following methods:
Motif administration program
Select
Connectivity and
New DLUR PU
from the
Services
menu on the Node window.
Command-line administration program
Issue the following command:
define_internal_pu
5.3.1 DLUR PU Configuration Parameters
The following parameters are required for DLUR PU configuration:
PU Name
For each DLUR PU on the local node, specify a PU name. This name should match the PU name configured
on the host. (SNAplus2 sends both the PU name and PU ID to the host to identify the PU. The host normally
identifies the PU by its PU name, or by the PU ID if it cannot find a matching PU name.)
DLUS Name
The fully qualified LU name of the host LU that supports DLUS.
In order to use DLUR, the DLUR component of SNAplus2 has to establish an LU-LU session with the DLUS
on the host.
Contact your SNA network planner to determine the name of the host LU.
Backup DLUS Name
This parameter is optional. The fully qualified LU name of a backup host LU that can be used if the one
specified by
DLUS Name is unavailable.
Contact your SNA network planner to determine the name of the host LU.
PU ID
The PU ID of the PU on the local node that supports connectivity to the host. The PU ID comprises two
hexadecimal strings, one of three digits (known as the block number), and one of 5 digits.
Each dependent LU is associated with a PU. Both the PU and the LU are configured on the host computer.
For each PU, you need to define a DLUR PU on the SNAplus2 node. The PU ID must match the PU ID
configured at the host for this PU.
In many cases the PU ID is the same as the node ID, so the node ID is the default. However, if you need
more than 255 dependent LUs to access a specific host, you need to configure multiple DLUR PUs, each
with up to 255 dependent LUs, and each with a different PU ID.
If you are not sure how to set this field, consult your SNA network planner.
In a VTAM configuration, the first three digits should match the IDBLK parameter in the PU definition, and
the last five digits should match the IDNUM setting.
Initially active
Whether the DLUR PU is to be activated automatically when the node is started. If you do not set this option,
the DLUR PU must be started manually.
