Before You Configure NIC Host Redundancy
If a directory does not support multimaster replication on the same machine as the NIC host, use NIC replication rather than NIC host redundancy. Without multimaster replication on the same machine, the NIC host must write its CORBA object references to the directory only when you start the NIC host, therefore a directory failure is unlikely to affect the operation of the NIC.
Before you configure NIC host redundancy, make sure that:
- NIC host software is installed on two separate machines for each set of NIC hosts to act as a redundant pair.
- Redundancy monitor software is installed on each system that is to act as a NIC monitor.
Usually, you install the monitor on the same machine as the SAE. A machine can support only one monitor.
For information about installing the NIC software and the redundancy monitor software, see SDX Getting Started Guide, Chapter 5, Installing the SDX-300 Software.
