installp version, the ODM entries might not exist and this command fails. In
that case, run java -version to determine if it exists on the system. Ensure that
the PATH statement for root allows for proper access to the level of Java that
you want to use. Try the which java command .
7. If an existing Internet connection is to be used and no modem connection is
needed, continue with step 12 on page 204. Complete the intervening steps
only if you are using a modem connection for primary or secondary access to
IBM.
Modem communication steps
8. Since your NAS Gateway 500 is your Electronic Service Agent gateway server,
your modem must be attached to serial port 2 and a console to serial port 1.
Make a record of which TTY device (for example,
tty1
) is mapped to serial
port 2 (location: 01–S2–00). The lsdev -Cc tty command lists all TTY devices
and their locations.
Verify the serial port TTY characteristics (such as tty1):
v
tty interface is RS232
v
baud rate is 9600 or higher
v
login enable is disabled
v
flow control is RTS
Use SMIT TTY to verify or change these settings.
Note: Do not change serial port 1 to login disabled . The service console
access requires login enable be set to enabled.
9. The modem is used to register your NAS Gateway 500 and to call the IBM
SDR. For security, only outbound calls are required by the Electronic Service
Agent, so the auto-answer capability of the modem should be disabled. An
asynchronous modem with a minimum communications speed of 9600 baud
and error correction (in the United States) is required. Set the highest possible
baud rate for your modem. Refer to local procedures in your country to see
what the modem requirements are for the Electronic Service Agent.
Complete the setup instructions from Appendix A, “Modem configurations,” on
page 255 before using the Electronic Service Agent.
10. On your Electronic Service Agent gateway server, ensure that Point-to-Point
Protocol (PPP) is installed and configured. PPP is only required if a modem is
going to be used for error reporting to IBM. Following are the PPP Link
configuration parameters with general minimum values. These values
represent the minimum configuration required by the Electronic Service Agent.
If you plan to use PPP for anything else, these settings can be adjusted as
needed. There should be an available 0.0.0.0 interface if properly configured.
To prevent the setup server command from posting an error message, the
0.0.0.0 IP should be defined in /etc/hosts or DNS.
Tip: Enter the command ps -ef | grep ppp . Look for pppcontrol. If you find
this, PPP is installed, configured, and running. Skip to the next step and check
diagnostics.
If you cannot locate pppcontrol, enter lslpp -l bos.net.ppp . This command
indicates whether the PPP file set is installed. If it is not installed, install the
code from the AIX disk using SMIT. Return here and complete the following
steps when PPP in installed:
a. Enter smit .
b. Select Communications Applications and Services .
c. Select PPP .
