| Hitachi AMS2000 configuration and setup example (Part 1) |
|
This is example of starting-up procedure and basic configuration
disk arrays Hitachi AMS2000 series. This article contains the following sections:Arrays overview
Hitachi disk arrays AMS2000 series is midrange storage systems. These arrays use a 3.5 inch SAS\SATA hard drives, and can work with SSD drives. This arrays fully operates on 3G SAS protocol witch provides a high speed data transfer operations and high I/O transfers. Comparing with Fibre Channel, SAS doesn’t use loops and FC switches and makes arrays more costeffective. One array can hold up to 480 disks and can take up to 3 racks.

Preparation for the startup
After checking all the cables in the rack of the array and connecting the array to the SAN
network, you should set a power mode of the array. This is posible to set using a rotary switch on the front side of the
controller shelf, as shown on Figure 1. Mode of the array must correspond to electrical sheme, lists of posible modes and descriptions listed in Table 2. Depends on the position of the switch arrays chose
cache memory operation modes and time for switching off. Switching between modes is done only available with the system powered off. Figure 1. Rotary switch
Table 2. Rotary switch modes
Do not set 0 and 2 when the UPS is not connected.
*1 : The duplication of the power supply system becomes unable to be done.
*2 : This cannot be used in the case of the single controller configuration.
DF-F800-VR4A is a Remote Adapter is optional part, whitch used to control power cuts and connects to a UPS monitoring server.
After the rotary switch is set up, you can start an array. To do this you need to power on power strip PDB at the back of the racks. Now you can start array by turning on the switch on the front panel. Then usally after about five minutes indicator READY LED, should light up green.
When doing this, when the READY LED (green) on the front of the Basic Chassis is blinking at high-speed in the dual controller configuration, the READY LED (green) on the front of the Basic Chassis lights up after it blinks at high-speed for the maximum of 30 to 50 minutes because the automatic download of the ENC firmware is operating.
Installing management software
Following completion of the start of array, you can start configuring it. To complete this operation you need to install array management software Hitachi Storage Navigator Modular 2, system requirements are listed in Table 3.
Table 3. System requirements
You should connect the ports of control array to Ethernet network or directly to the management computer. By default, the IP addresses of controllers uses foloving:
CTL #0 - 10.0.0.16; 192.168.0.16; 192.168.233.16; 172.23.211.16; 10.197.181.16
CTL #1 - 10.0.0.17; 192.168.0.17; 192.168.233.17; 172.23.211.17; 10.197.181.17 subnet mask 255.255.255.0
To enter the Hitachi Storage Navigator Modular 2 type in your browser following address: http://xxxx:23015/StorageNavigatorModular/ or https: / /xxxx: 23016/StorageNavigatorModular/ for the https, where xxxx - IP address of the management computer wnere Hitachi Storage Navigator Modular 2 installed. Program will prompt you to login to the program, as shown on Figure 2. When Hitachi Storage Navigator Modular 2 was newly installed, enter the temporarily registered user ID “system” and password “manager”.
Figure 2. Login window
The Hitachi Storage Navigator Modular 2 is activated in the Normal Mode and the main window is displayed. You can execute the display of the Hitachi Storage Navigator Modular 2 Operation Mode and state of the failure monitoring and the following functions in the main window.
For the operation of each function, refer to the page explaining each function.
• Registration of the disk array subsystem (registration, deletion, change, and properties display)
• Execution of the failure monitoring and setting of the failure monitoring option
• Change of the Operation Mode
• Display of the version
Figure 3. Main window
Hitachi Storage Navigator Modular 2 has three Active Modes, that is, the Normal Mode, Management Mode, and Maintenance Mode. In the Normal Mode, the program displays the configuration and statuses of the disk array. In the Management or Maintenance Mode, it can set the configuration of the disk array in addition to the function in the Normal Mode.
Changing the Normal Mode to the Maintenance Mode
Change the Operation Mode from the Normal Mode to the Maintenance Mode.
Check that the “mode” file exists in the following directory:\HiCommand\StorageNavigatorModular\conf.
If there is no mode file, create a mode file (without extension) and write the following letters in one line "StorageNavigatorModular". However, do not insert line feeds.
Store the created mode file in the following place:\HiCommand\StorageNavigatorModular\conf.
Put a checkmark in the array subsystem to operate on the main window, and press the [Ctrl] key, [Shift] key and the [E] key at the same time.
It is displayed as “maintenance mode” in [Operation Mode] of the upper part of the main window, and Hitachi Storage Navigator Modular 2 is operated in the maintenance mode, as shown on Figure 4.
Figure 4. Maintenance mode
Adding the disk array subsystem to be operated in order to operate it from the Hitachi Storage Navigator Modular 2.
Click the [Add Array] button in the “Subsystems” window of the main window. “HSNM2_Add Array Wizard” window is displayed.
Figure 5. HSNM2_Add Array Wizard
The array subsystem register is searched. Specify a search method and a range to search by a host name or an IP address.
Figure 6. IP address search window
The search result is displayed. Specify the array subsystem to register, and click the [Next] button. Enter the IP address only in the Control Unit to which the
LAN cable is connected. If the IP address is entered in a Control Unit to which the LAN cable is not connected, an error is caused.
