Disk sets in SVM

Using SVM disk sets even with single host (non-clustered) does makes sense for external connected storage. If you for some reason want to reinstall system or install new one but want to preserve all SVM made raids then disk sets make it really easy for you. Disk sets are really usefull if you want to move your external storage from one system to another. Below example what I did today - system was reinstalled but I wanted to preserve all SVM volumes on external JBOD. And if there's only one host using these disks then you probably want to set auto-take on.
