The purpose of this document is to give a brief overview of the migration process which allows SNA profiles to be converted from the format used by SNA Services/6000 V1.2 or Communications Server V4 for AIX to the format used by IBM eNetwork Communications Server V5 for AIX. This document is one in a series of documents that aid in Communications Server V5 configuration.
For more information, see the IBM eNetwork Communications Server for AIX Migration Guide, SC31-8585.
The eNetwork Communications Server home page is available at:
http://www.software.ibm.com/enetwork/commserver/
The AIX and RS/6000 product documentation library is also available:
http://www.rs6000.ibm.com/resource/
Before upgrading the AIX operating system, and before installing IBM eNetwork Communications Server V5, complete the following steps.
exportsna -f FILENAME
FILENAME specifies the output file that will contain all of the exported SNA Services profiles.
Upgrade the AIX Operating System to AIX Version 4.1.5 or a later version. Then install IBM eNetwork Communications Server V5.
The overall migration process has two parts: converting the Version 1.2 profiles to Version 4.2 format, and then converting the Version 4.2 format to Version 5 format.
Migrate the SNA Services Version 1.2 profiles to Communications Server V4.2 format with the following command:
migratesna -s SOURCEFILE [-t TARGETFILE] [-l NETWORK.CPNAME]
Parameters:
NOTE: Because SNA Services/6000 allowed multiple control points and later SNA products allowed only one, the fully qualified local control point (CP) name is what you want this RS/6000's single control point name to be. This name needs to be unique on your SNA network. One common convention is to use the system's TCP/IP HOSTNAME as its SNA CP NAME also.
Migrate the Version 4.2 profiles to Version 5 format with the following command:
snamig -o -f OldTextConfigFile
OldTextConfigFile is the same file name as TARGETFILE from the preceding section
of this document.
The default settings for the optional flags of this command create the following file names for the converted profiles:
/etc/sna/sna_node.cfg
/etc/sna/sna_domn.cfg
/etc/sna/sna_tps
First, start the SNA DAEMON with the command sna start; then start the SNA NODE with the command snaadmin init_node. To use the preferred method of controlling and administering eNetwork Communications Server V5 for AIX, start the graphical interface tool with the command xsnaadmin. If a graphics interface is not available, SNA resources may be started manually from the command line or by using smit.
