command. On Windows, you must enclose the name between two backslashes (\) in addition to other delimiters. For example, the following name is used in a command that runs under Windows: [\"Engineering\"] For a Linux system when used in a script file, the name appears as: ["Engineering"] Configuring a Storage Array When you configure a storage array, you can maximize data availability by ensuring that data is quickly accessible while maintaining the highest level of data protection possible. The speed at which a host can access data is affected by the disk group RAID level and the segment size settings. Data protection is determined by the RAID level, hardware redundancy (such as global hot spares), and software redundancy (such as the Snapshot feature). In general, you configure a storage array by defining the following entities: • A disk group and associated RAID level • The virtual disks • Which hosts have access to the virtual disks This section explains how to use the script commands to create a configuration from an array of physical disks. Determining What is on Your Storage Array Even when you create a configuration on a previously unconfigured storage array, you still need to determine the hardware and software features that must be included with the storage array. When you configure a storage array with an existing configuration, you must ensure that your new configuration does not inadvertently alter the existing configuration, unless you are reconfiguring the entire storage array. For example, to create a new disk group on unassigned physical disks, you must determine which physical disks are available. The commands described in this section enable you to determine the components and features in your storage array. 44 Configuring a Storage Array
