Planning Storage Configurations
62 HSG80 ACS Solution Software V8.8 for IBM AIX Installation and 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 64, to help you.
2. Review configuration rules. See "Configuration Rules for the Controller",
page 65.
3. Familiarize yourself with the current physical layout of the devices and their
addressing scheme. See "Addressing Conventions for Device PTL", page 67.
4. Choose the type of storage containers you need to use in your subsystem. See
"Choosing a Container Type", page 76, for a comparison and description of
each type of storageset.
5. Create a storageset profile (described in "Creating a Storageset Profile",
page 78). Fill out the storageset profile while you read the sections that
pertain to your chosen storage type:
— "Planning Considerations for Storageset", page 80
— "Mirrorset Planning Considerations", page 82
— "RAIDset Planning Considerations", page 84
— "Partition Planning Considerations", page 88
— "Striped Mirrorset Planning Considerations", page 86
6. Decide which switches you need for your subsystem. General information on
switches is detailed in "Specifying Storageset and Partition Switches",
page 91.
— Determine the unit switches you want for your units ("Specifying Unit
Switches", page 97).
— Determine the initialization switches you want for your planned storage
containers ("Specifying Initialization Switches", page 93).
7. Create a storage map ("Creating Storage Maps", page 98).
8. Configure the storage you have now planned using one of the following
methods:
— Use SWCC. See the SWCC documentation for details.
