Configuration Procedures
Creating a New Array
This section provides instructions for creating or modifying new arrays after
you have installed your operating system. If you are configuring a new array,
the configuration wizard leads you through the process. If you want to bypass
the wizard, use the following procedures to create your array.
Creating a new array involves the following general steps:
■ Choosing a controller for the array
■ Grouping physical drives of the same size into an array
■ Subdividing the array into one or more logical drives
The following example illustrates how to use the Array Configuration Utility
to create a new array.
For this example, make the following assumptions:
■ Array A contains at least one physical drive that has been configured as
a logical drive and contains the operating system.
CAUTION: Do not modify the logical drive that contains the operating system.
Modifying this drive can result in loss of data.
■ Four 9.1-GB drives and two 4.3-GB drives are connected to the
Integrated Smart Array Controller. The operating system is not installed
on any of these drives.
■ Two new arrays will be configured. Array B consists of three 9.1-GB
drives with the fourth 9.1-GB drive used as a spare. Array C contains
the two 4.3-GB drives.
■ The fault-tolerance method for all logical drives on Array B is RAID 5,
Distributed Data Guarding. The fault-tolerance method for all logical
drives on Array C is RAID 1, Drive Mirroring.
