Sample Configurations

 

Example Two - One Adoptive Node for Two Packages with File Lock Migration

 

Figure 3-4 shows this sample configuration after host basil has failed.

 

Host sage has adopted pkg02. The package control option prevents host

 

sage from adopting another package, so host sage is no longer an

 

adoptive node for pkg01.

This sample configuration also enables the File Lock Migration feature.
