Final answer:
To disable site affinity for multi-site clusters, you need to adjust the cluster configuration settings specific to the technology used for managing the cluster. This may involve altering resource properties or using command-line tools.
Step-by-step explanation:
Disabling site affinity for multi-site clusters typically involves changing the cluster configuration settings to prevent the cluster from preferring one site over another for the location of resources. This is a process that will depend on the specific technology or software you're using to manage the cluster. For example, in Windows Server Failover Clustering (WSFC), it may involve adjusting the properties of cluster resources to ensure that they do not have a preferred site, or using PowerShell commands to set the site affinity settings to 'None'. Each cluster management tool will have its own method and therefore, referring to the official documentation or support resources for that specific tool is necessary for detailed instructions.
