Chapter 4. IBM System Storage DS planning and configuration 185
5. After completion, the Storage Manager shows the arrays, logical drives, and hot spares
created automatically based on your input, as shown in Figure 4-48.

4.9.4 Manual configuration
In this section, we cover the necessary steps to configure available storage subsystem
capacity into logical drives using the Storage Manager interface. We already covered the
automatic procedure, where the options are limited. Now we cover the additional parameters
that you can select to better configure the storage for your environment.
We split the tasks into two sections, starting with the creation of global hot spares. We
recommend performing this task first to ensure that you have enough spare drives before
creating the logical drives.
Defining hot spare drives
The concept of a hot spare drive is explained in 4.1.3, “Hot spare drive” on page 114. Here we
cover the available methods of defining hot spare drives with Storage Manager V10.60.
Because we plan for this configuration, we start assigning hot spare drives and then continue
with the arrays.
