Creating a Storageset Profile
Creating a profile for your storagesets, partitions, and devices can simplify the
configuration process. Filling out a storageset profile helps you choose the storagesets
that best suit your needs and to make informed decisions about the switches you can
enable for each storageset or storage device that you configure in your subsystem.
The example storageset profile shown in Figure 2–6. Appendix A contains blank profiles
that you can copy and use to record the details for your storagesets. Use the information in
this chapter to help you make decisions when creating storageset profiles.
