Creating a Communication Path<br />
Creating a Communication Path<br />
Before configuring an SPS communication path between servers, verify the hardware and software<br />
setup. See the Configuration section for requirements.<br />
Configuration Notes<br />
• You should configure no more than one shared disk comm path between servers.<br />
• Shared Disk comm paths are supported for two-server clusters only.<br />
• For greater than two-server clusters, use multiple TCP/IP comm paths for heartbeat<br />
redundancy. A priority value is used to tell SPS the order in which TCP/IP paths to a given<br />
remote server should be used.<br />
• IMPORTANT: Supported configurations require that you define redundant comm paths so that<br />
the failure of a single communication line will not cause an unnecessary failover. If a single<br />
comm path is used and the comm path fails, SPS hierarchies may come in service on multiple<br />
servers simultaneously. This is known as "split-brain". Additionally, heavy network traffic on a<br />
