Chapter 1. Introduction to the 3ware Command Line Interface Using the command interface interactively You can use 3ware CLI interactively, entering commands at the main prompt and observing the results on the screen. To use the CLI interactively 1 Enter the following command: ./tw_cli The main prompt is displayed, indicating that the program is awaiting a command. //localhost> 2 At the CLI prompt, you can enter commands to show or act on 3ware controllers, units, and drives. For example, //

Working with 3ware CLI Using an input file to execute a script You can operate 3ware CLI scripts by executing a file. The file is a text file containing a list of CLI commands which you have entered in advance. Each command must be on a separate line. Syntax tw_cli -f Where is the name of the text file you want to execute. Example tw_cli -f clicommand.txt This example executes the file clicommand.txt, and runs the CLI commands included in that file. Scripting example Fol

Chapter 1. Introduction to the 3ware Command Line Interface Conventions The following conventions are used through this guide: • In text, monospace font is used for code and for things you type. • In descriptions and explanations of commands, a bold font indicates the name of commands and parameters, for example, /c0/p0 show all. • In commands, an italic font indicates items that are variable, but that you must specify, such as a controller ID, or a unit ID, for example, /c0/p0 show attribut

Understanding RAID Levels and Concepts RAID Concepts The following concepts are important to understand when working with a RAID controller: • Arrays and Units. In the storage industry, the term “array” is used to describe two or more disk drives that appear to the operating system as a single unit. When you work with 3ware software, “unit” is the term used to refer to an array of disks that is configured and managed through the 3ware software. Single-disk units can also be configured in th

Chapter 1. Introduction to the 3ware Command Line Interface Available RAID Configurations The following RAID levels and configurations are available for drives attached to a 9590SE-4ME 3ware RAID controller: • RAID 0 • RAID 1 • RAID 5 • RAID 10 • Single Disk • Hot Spare Note: You may notice mention of RAID 50 in the Command Syntax sections of the CLI Guide. RAID 50 requires six or more drives, and so is not available using the 9590SE-4ME. For how to co

Understanding RAID Levels and Concepts Figure 1. RAID 0 Configuration Example RAID 1 RAID 1 provides fault tolerance and a speed advantage over non-RAID disks. Also known as a mirrored array. Mirroring is done on pairs of drives. Mirrored disk arrays write the same data to two different drives using RAID 1 algorithms (see Figure 2). This gives your system fault tolerance by preserving the data on one drive if the other drive fails. Fault tolerance is a

Chapter 1. Introduction to the 3ware Command Line Interface Figure 3. RAID 5 Configuration Example RAID 10 RAID 10 is a combination of striped and mirrored arrays for fault tolerance and high performance. When drives are configured as a striped mirrored array, the disks are configured using both RAID 0 and RAID 1 techniques, thus the name RAID 10 (see Figure 4). A minimum of four drives are required to use this technique. The first two drives are mirror

Understanding RAID Levels and Concepts Single Disk A single drive can be configured as a unit through 3ware software. (3DM 2 or CLI). Like disks in other RAID configurations, single disks contain 3ware Disk Control Block (DCB) information and are seen by the OS as available units. Single drives are not fault tolerant and therefore not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss. Hot Spare A hot spare is a single dri

Chapter 1. Introduction to the 3ware Command Line Interface Using Drive Capacity Efficiently To make the most efficient use of drive capacity, it is advisable to use drives of the same capacity. This is because the capacity of each drive is limited to the capacity of the smallest drive in the unit. The total array capacity is defined as follows: Table 3: Drive Capacity RAID Level Capacity Single Disk capacity of the drive RAID 0 (number of drives) X (cap
