While deploying a vRealize Log Insight (vRLI) cluster with a VIP using vRealize Suite Lifecycle Manager 8.1, you receive this error:

Error Code: LCMVRLICONFIG40091 Error occured while configuring vRLI Integrated Load balancer. {“errorMessage”:“Specified IP address is not available. It is already held by another host in the network”,“errorCode”:“LOAD_BALANCER_ERROR”, “errorDetails”:{“errorCode”:“com.vmware.loginsight.api.errors.loadbalancer.ip_address_unavailable”}}

This is clearly due to an issue with the VIP that has been configured. Check both forward and reverse DNS records of course. But what if that’s OK? In my particular instance, the IP addresses for the vRLI node and the vRLI VIP IP addresses were not in the same subnet. Once we sorted those out vRLI deployed just fine.
