Configuration Guide
Where to Start
The following procedure outlines the steps to follow when planning your storage
configuration.
See Appendix A to locate the blank templates for keeping track of the containers
being configured.
1. Determine your storage requirements. Use the questions in “Determining Storage
Requirements,” page 2–3, to help you.
2. Review configuration rules. See “Configuration Rules for the Controller,” page
2–3.
3. Familiarize yourself with the current physical layout of the devices and their
addressing scheme. See “Addressing Conventions for Device PTL,” page 2–4.
4. Choose the type of storage containers you need to use in your subsystem. See
“Choosing a Container Type,” page 2–14, for a comparison and description of
each type of storageset.
5. Create a storageset profile (described in “Creating a Storageset Profile,” page
2–16). Fill out the storageset profile while you read the sections that pertain to
your chosen storage type:
— “Planning Considerations for Storageset,” page 2–18
— “Mirrorset Planning Considerations,” page 2–21
— “RAIDset Planning Considerations,” page 2–22
— “Partition Planning Considerations,” page 2–26
— “Striped Mirrorset Planning Considerations,” page 2–24
6. Decide which switches you need for your subsystem. General information on
switches is detailed in “Specifying Storageset and Partition Switches,” page 2–28.
— Determine the unit switches you want for your units (“Specifying Unit
Switches,” page 2–33).
— Determine the initialization switches you want for your planned storage
containers (“Specifying Initialization Switches,” page 2–29).
7. Create a storage map (“Creating Storage Maps,” page 2–34).
8. Configure the storage you have now planned using one of the following methods:
— Use SWCC. See the SWCC documentation for details.
