Identify Any Communications Lines Using the TRSA

The subsystems and utilities that use the SLSA subsystem to access an TRSA are

illustrated in Figure 1-2.

Use the following procedure to help you identify the subsystems and utilities that are

configured to use a TRSA. Specific instructions are provided for identifying SNAX/TR

lines.

Perform the following steps:

1. Determine the name of the logical interface (LIF) and physical interface (PIF)

associated with the TRSA to be relocated.

a. Use the SCF INFO LIF command:

->SCF INFO LIF $ZZLAN.*

b. Scan the output of the command for the name of the TRSA to be relocated.

Make a note of the LIF name and PIF name.

Example 4-1

shows the output of this command. The Logical interface (LIF)

name is shown in the Name column and the physical interface (PIF) name is

shown in the PIF column. The name of the Token-Ring ServerNet adapter

(TRSA) CRU is the first part of the PIF name (for example, E0153).

The PIF name indicates the physical port on the TRSA. For example, the PIF

named E0153.1.A. identifies the UTP (RJ-45) port on the TRSA named E0153.

In this example, the LIF associated with the TRSA named E0153 is named

L018.

2. Determine the TCP/IP processes, subnets, and Internet Protocol (IP) addresses

associated with the LIF for the TRSA to be relocated.

a. Use the SCF INFO SUBNET command:

->INFO SUBNET $*.*

b. Scan the output of the command for the LIF you identified in Step 1 and then

find the associated TCP/IP process, subnet, and IP address. Make a note of this

Note. SNAX/XF and SNAX/APN lines that use token-ring connections are referred to as

SNAX/TR lines in the following procedure.

Note. Make a note of the information you obtain during this procedure. You can record this

information on the planning worksheet provided or you can use the SCF LOG command to

capture both the command and the display to a file. To start logging, type LOG logfilename

at the SCF prompt. To stop logging, type LOG at the SCF prompt.
