About this guide
1 CLI setup and overview The Command Line Interface (CLI) is used to configure and manage the array controller and its storage. Tasks include configuring logical storage units (LUNs), limiting access to storage, viewing system and component information, configuring iSCSI elements, and setting up the management interface. The CLI can also be used to display system setup information and status, and, provide information on devices that are attached to the controller.
2. Launch PuTTY on a PC that is connected to the same LAN as the MSA1510i. 3. Enter the IP address of the MSA1510i management port in the Host Name (or IP address) field. 4. Verify that the SSH radio button is selected. 5. Click Open. The SSH shell opens and you are prompted to log on. 6. Enter your username and password. NOTE: When using SSH, Telnet, or the HP Storage Management Utility (SMU) to connect to the MSA1510i management port, you are required to log on.
1. Ensure that the Telnet interface is enabled. To enable Telnet, use the SMU. For more information, see the HP Storage Management Utility user guide. 2. From any PC that is connected to the same LAN as the MSA, click StartRun to open the Run dialog box. 3. Enter the following command: telnet [] where [] is the IP address of the MSA management port. The Telnet shell opens and you are prompted to log on. 4. Enter your username and password.
2. Open your terminal emulation software. The following instructions demonstrate using HyperTerminal: a. Click StartRun to open the Run dialog box. Type hypertrm.exe, and then click OK. When accessed for the first time, the New Connection dialog box is displayed. b. In the New Connection dialog box, type a name to associate with the connection between the controller and the host server, and then click OK. The Connect To dialog box is displayed. c.
• Commands are not case sensitive and must be typed in full. • The CLI does not support line-continuation characters. If all characters of a command cannot fit on one line of the CLI, the command wraps to the next line on the screen. The maximum command length is 255 characters. Example command The following command has three portions: the basic command and three operands: add unit 0 data=”disk101-disk103” raid_level=0 The basic command is add unit.
CLI setup and overview
2 Initial configuration sequence The MSA can be completely configured using the CLI. If you want to use the HP Storage Management Unit (SMU), but the factory default management network settings do not work in your environment, see Configuring static management settings. The example commands shown in this chapter are provided as a general reference and may differ from the commands needed for your configuration. The examples show the command that is typed in at the CLI prompt and the system response.
2. Configure a logical drive on a set of disks using the add unit command: CLI> add unit 0 raid_level=5 data=disk101-disk105 size=100gb Logical Unit size = 102398 MB RAID overhead = 25597 MB Total space occupied by new unit = 127995 MB Free space left on this volume: = 1064201 MB Unit 0 is created successfully. 3. Repeat the add unit command as needed, to configure the storage in to multiple logical drives.
10. Use the bind portal_group to bind the portal group to the iSCSI target just created: CLI> bind portal_group pg1 target1 The portal group was bound successfully to the target. 11. Bind logical drives to the iSCSI target using the bind unit command: CLI> bind unit 0 target1 1 On Target target1: LUN 1 mapped to Unit 0 Alias: lun1t1 12. Repeat the bind unit command as required to bind several logical drives to the target. 13.
Configuring Access Controls for LUN access NOTE: The steps in this section assume that you already have a basic iSCSI setup configured. 1. Use the set acl command to enable Access Controls on the target: CLI> set acl target1 on Access Controls Enabled on Target target1 2.
• To a. b. c. iSNS enabled manually add iSNS servers Use the set isns command to change the iSNS server discovery mode: CLI> set isns server_discovery=manual iSNS parameters set. Use the add isns_server command to add the IP address of the iSNS server: CLI> add isns_server 20.20.20.26 The iSNS server was added successfully. Alias: isns1 Use the set discovery command to enable iSNS discovery on the iSCSI target.
4. [Optional] If required, enable access to the CLI via Telnet (not recommended) using the set service command: CLI> set service telnet on CAUTION: The Telnet protocol is not a secure method of transmitting data over a network. Because Telnet does not encrypt data, anyone with the proper knowledge and tools can read information being sent over the network.
3 Command reference Command overview The CLI uses the following basic types of commands: add Creates new configuration elements. bind Creates associations between iSCSI elements. delete Removes configuration elements. help Displays all possible commands or a detailed description of a specified command. reset Restores the default values of configuration elements. set Changes the value of configuration elements.

A Storage overview • • • • Arrays and logical drives Fault-tolerance levels Comparison of RAID Methods Choosing a RAID level Arrays and logical drives The capacity and performance of a single physical hard drive is adequate for home users. However, business users demand higher storage capacities, higher data transfer rates, and greater protection against data loss when a hard drive fails.
S1 S2 S3 S4 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 D1 D2 D3 15312 Figure 3 Data striping (S1-S4) and data blocks (B1-B12) on multiple physical drives (D1, D2, D3) For data in the logical drive to be readable, the data block sequence must be the same in every stripe. This sequencing process is performed by the array controller, which sends the data blocks to the drive write heads in the correct order.
that was originally on the failed drive to the online spare. The system is quickly restored to full RAID-level data protection. (In the unlikely event that another drive in the array fails while data is being rewritten to the spare, the logical drive will still fail.) A spare is assigned to an array and is automatically assigned to all logical drives in the same array. You do not need to assign a separate spare to each array; you can configure one hard drive to be the spare for several arrays.
S1 B1 B2 B3 B4 S2 B5 B6 B7 B8 D1 D2 D3 D4 D5 D6 D7 D8 S1 B1 B2 B3 B4 S2 B5 B6 B7 B8 15315 Figure 6 RAID 1+0 array, with eight physical hard drives (D1 through D8) In each mirrored pair, the physical drive that is not busy answering other requests answers any read request sent to the array. (This behavior is called load balancing.) If a physical drive fails, the remaining drive in the mirrored pair can still provide all the necessary data.
Table 5 RAID 5 features Advantages Disadvantages High read performance. Relatively low write performance. No loss of data if one physical drive fails. Loss of data if a second drive fails before data from the first failed drive is rebuilt. More usable drive capacity than RAID 1+0, because parity information requires the storage space equivalent to one physical drive.
