Defining Connectivity Components

Defining DLUR PUs

For each DLUR PU on the local node, specify a PU name. The name does not need to match the PU name configured on the host.

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.

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.

On an AS/400 system, the PU ID is configured in the EXCHID parameter.

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.
