Unable to Define a Low-Priority LUA LU in SNA Server Manager

• Microsoft SNA Server, versions 3.0, 3.0 SP1

SYMPTOMS

When you define an LUA LU in SNA Server Manager, there is no way to indicate that the LUA LU is low priority. Instead, all LUA LUs created using SNA Server Manager are defined as high priority, so that all traffic flowing over the LUA LU is handled at the same priority as 3270 LUs.

You can set the priority in SNA Server version 2.x. The SNA Server 2.x Administrator program supports configuration of the LUA LU priority through the "High Priority LU" checkbox located in the LUA LU Properties dialog box.

RESOLUTION

To work around this problem, do one of the following:

• Use the Snacfg.exe command line configuration program to add a low- priority LUA LU, using the following command:

  SNACFG LUA <luaname> /ADD /CONNECTION:<name> /LUNUMBER:<value> /HIGHPRIORITY:No

  -OR-



• To change an existing LUA LU to low priority, use this command:

  SNACFG LUA <luaname> /HIGHPRIORITY:No

  -OR-



• If the above command-line configuration method is not possible, see the fix to SNA Server Manager referenced below.

STATUS
