Additional Redundant Server Procedures 6-3
Use the following format to make your separate line entries into this file.
<IP Address> <Computer Name> <Computer Name0> <Comment>
<IP Address> <Computer Name1>
3. Click File
⇒
Exit and click Yes to save the Hosts file.
4. Repeat Step 1 to Step 3 for each Server node in your system.
5. Use the PING utility to determine if both Servers can see each other by
name and IP address.
Where: is:
IP Address the assigned internet address with no leading zeros. For example, a
typical address could be >192.168.0.1<.
Computer Name a base name of up to 13 characters, which must be the same for each
ProcessLogix Server in the system.
• In a redundant Server system, you must append a letter to the
base name to identify the PC’s function in the system architecture
with the letters a and b for the Primary and Secondary Servers,
respectively.
EXAMPLE
For example, if you have a redundant Server system and
you assign a base name of PLX1, the Computer Name
for the Primary Server and Secondary Engineering
Repository Database (ERDB) would be >PLX1A<, the
Secondary Server and Primary ERDB would be
>PLX1B<.
Computer Name0 the computer name appended with a 0 to show its association with
the first Ethernet adapter card.
Computer Name1 the computer name appended with a 1 to show its association with
the second Ethernet adapter card (in a dual Local Area Network (LAN)
system).
EXAMPLE
For example, if you have a redundant Server system with
a dual LAN and a base computer name of >PLX1<, the
Computer Names would be >PLX1A0<, >PLX1B0<,
and >PLX1A1<, >PLX1B1< for their respective
addresses. If you have a single LAN system, you only
need to append the Computer Name with a “0”.
Comment any additional descriptive data you want to include for a given
Computer Name.
• You must begin each entry with the number symbol >#<.
• An example of a Host file with additional Host name entries and
comments is shown above for reference.
• The Hosts file includes a default IP address of >127.0.0.1< for a
localhost. Do not delete this default entry from the Hosts file.
