Clustering system and remote host connection

The remote host must be able to communicate with the local host using the local host name of HULFT. Register the virtual IP address and linked local host name of HULFT to the DNS or the 'hosts' file so that the virtual IP address can be looked up using the local host name. This allows HULFT access via the same IP address (virtual IP address) and host name (virtual host name) even in the event of a failover.

<Setting example>

Local Host Name for HULFT

:

uxcluster

Virtual IP address

:

172.16.10.10

ACTIVE server

Node name

:

uxcluster1

Actual IP address

:

172.16.10.11

STANDBY server

Node name

:

uxcluster2

Actual IP address

:

172.16.10.12

Figure 3.2 Example Configuration of Host Name and IP Address

<Example of remote side 'hosts' file>

172.16.10.10  uxcluster

Note

The actual IP address or node name may be displayed in a log or in the console logs of the remote host. However, this does not cause abnormal behavior with HULFT.

For methods to prevent this phenomenon, refer to Notes on connecting from HULFT in a clustering environment.
