154 IBM System Storage DS3000: Introduction and Implementation Guide
Figure 8-30 Create Host Group - Complete
8.3 Configure Storage
The second part of the Configure Tab is Storage (Figure 8-14 on page 143). The first three
tasks are for basic configuration:
򐂰 Automatic Configuration
򐂰 Configure Hotspares
򐂰 Create Logical Drives
The other tasks are for more advanced functions:
򐂰 Create FlashCopy Logical Drives
򐂰 Create Logical Drive Copies
These tasks set up the arrays and logical drives on your storage subsystem. Arrays are sets
of physical drives that the controller logically groups together to provide one or more logical
drives to an application or an cluster. A logical drive is a logical structure you create on a
storage system or data storage. Creating arrays is one of the most basic steps and is required
before you can start using the physical disk space. That is, you divide your disk drives into
arrays and create one or more logical drives inside each array. The first three wizards allow
you to set up this basic configuration on your storage subsystem. More information about
arrays and their RAID Levels is in 4.1, “Storage subsystem concepts” on page 45.
Note: Unless you have unique requirements, we recommend to use the third task “Create
Logical Drive” and then the Automatic option (8.3.3, “Create Logical Drives” on page 161).
This usually ensures the most optimal balance between capacity, performance and
redundancy. A manual configuration will typically not have the most optimal settings.
