Robert, I did not understand whether you ran into an issue when you configured the zone w/o IP address and installed sun cluster or just thinking about what is the best way to use the IP addresses. Let me make few comments and also ask few questions to understand it better:
1) Which Sun Cluster release are you running? How are you using or planning to use the zone with Cluster - failover container, zone node or the latest zone cluster feature? 2) I did not understand the following: >However it seems that the way the IP address is configured in in this scenario >there >is a race condtition when if zone boots too quickly (everything is cached in a >memory) >some services which depend on network will be started before the IP address >has been >configured which is causing them to fail, etc. For example it is often a case >with ssh if >configured to bind to the ip address and not to *. Sometimes with other apps >which can't >contact dns, etc. Are you saying that the Solaris ssh service binding to the Sun Cluster logical host IP address? Won't that be a problem when the IP address fails over another node? 2) There are different purposes for the Zone public IP address and the Logical Host resource IP address. The zone cluster IP address grants the network access to the Solaris zone and I believe it's an optional thing. Sun Cluster logical host resources are used to failover the resources between the cluster nodes. So that said, I am not sure I understand your rationale behind comparison or the choice you are trying make between them. 3) Solaris supports zones with out public IP address, and Sun Cluster zone node feature works with this. That means with zone nodes feature, you can create zones w/o the IP address configured. Then can create the logical host resources to failover the application beween the zone nodes. However, Sun cluster zone cluster feature requires all zones part of the zone cluster to have the public IP address. I might be missing something here, more details would be appreciated.
