High availability features

Two interconnected controllers ensure that the failure of a controller component does not disable the system. A single controller can fully support an entire system until the defective controller, or controller component, is repaired. For EVA8000 configurations with more than four disk drive enclosures, the complete data redundancy configuration includes two Loop A and two Loop B data paths. For EVA4000 and EVA6000 configurations, data redundancy is accomplished with two Loop A data paths.

Each HSV210 controller has two lead-acid cache battery assemblies that provide power to the cache memory while each HSV200 controller has one. Each battery assembly has three lead-acid, non–spillable cells. When both battery assemblies are fully charged, they can provide power to the cache for up to 96 hours.

Operator control panel

The operator control panel (OCP) provides a direct interface to each controller. From the OCP you can display storage system status and configuration information, shut down the storage system, and manage the password. The OCP includes a 40-character LCD alphanumeric display, six pushbuttons, and five status indicators See Figure 32. HP Command View EVA is the tool you will typically use to display storage system status and configuration information or perform the tasks available from the OCP. However, if HP Command View EVA is not available, the OCP can be used to perform these tasks.

Status indicators

The status indicators indicate the internal status of the controller, as described in document HP StorageWorks EVA 4000, 6000, 8000 - OCP Indicators . During initial setup, the status indicators might not be fully operational.

Navigation buttons

The information displayed by the OCP, the data you can enter, and the navigation push button functions depend on the alphanumeric display mode.

To simplify presentation and to avoid confusion, the push button reference names, regardless of labels, are left , right , top , and bottom .

LCD

The two LCD rows display up to 20 alphanumeric characters per row. The LCD alternates between displaying the Storage System Name and the World Wide Node (see Figure 5).
NOTE: An active (flashing) display, an error condition message, or a user entry (pressing a push button) overrides the default display. When none of these conditions exist, the default display is active after approximately 15 seconds.

  • OCP firmware version

  • Controller version

  • XCS version

NOTE: The terms PPC, Sprite, Glue, SDC, CBIC, and Atlantis are for development purposes and have no significance for normal operation.

When viewing the software or firmware version information, pressing displays the Versions Menu tree.

To display System Information:
  1. The default display alternates between the Storage System Name display and the World Wide Node display.

    Press any push button to select the Storage System Menu Tree display.

  2. Press until the desired Versions Menu option appears, and then press or to move to sub–menu items per the System information functions table .

Shutting down the system

CAUTION: To power off the system for more than 96 hours, use HP Command View EVA.
You can use the Shutdown System function to implement the shutdown methods listed below. These shutdown methods are explained in the Shutdown methods table.

To ensure that you do not mistakenly activate a shutdown procedure, the default state is always NO , indicating do not implement this procedure . As a safeguard, implementing any shutdown method requires you to complete at least two actions.

Shutdown methods
LCD prompt
Description
Restart System?
Implementing this procedure establishes communications between the storage system and HP Command View EVA. This procedure is used to restore the controller to an operational state where it can communicate with HP Command View EVA.
Power off system?
Implementing this procedure initiates the sequential removal of controller power. This ensures no data is lost. The reasons for implementing this procedure include replacing a drive enclosure.
Uninitialize?
Implementing this procedure will cause the loss of all data. For a detailed discussion of this procedure, see Uninitializing the System.

Shutting the controller down

Use the following procedure to access the Shutdown System display and execute a shutdown procedure.
NOTE: HP Command View EVA is the preferred method for shutting down the controller. Shut down the controller from the OCP only if HP Command View EVA cannot communicate with the controller.

Shutting down the controller from the OCP removes power from the controller on which the procedure is performed only. To restore power, toggle the controller’s power switch.

CAUTION: If you decide NOT to power off while working in the Power Off menu, Power Off System NO must be displayed before you press Esc . This reduces the risk of accidentally powering down.
  1. Press three times to scroll to the Shutdown Options menu.

  2. Press to display Restart.

  3. Press to scroll to Power Off.

  4. Press to select Power Off.

  5. Power off system is displayed. Press Enter to power off the system.

Restarting the system

To restore the controller to an operational state, use the following procedure to restart the system.
  1. Press three times to scroll to the Shutdown Options menu.

  2. Press to select Restart.

  3. Press to display Restart system? .

  4. Press Enter to go to Startup.

No user input is required. The system will automatically initiate the startup procedure and proceed to load the Storage System Name and node World Wide Name information from the operational controller.

Uninitializing the system

Uninitializing the system is another way to shut down the system. This action causes the loss of all storage system data. Because HP Command View EVA cannot communicate with the disk drive enclosures, the stored data cannot be accessed.
CAUTION: Uninitializing the system destroys all user data. The WWN will remain in the controller unless both controllers are powered off. The password will be lost. If the controllers remain powered on until you create another storage system (initialize via GUI), you will not have to re-enter the WWN.
Use the following procedure to uninitialize the system.
  1. Press three times to scroll to the Shutdown Options menu.

  2. Press to select Restart.

  3. Press twice to display Uninitialize System

  4. Press to display Uninitialize?

  5. Select Yes and press Enter . The system is now uninitialized.

Password options

The password entry options are:
  • Entering a password during storage system initialization (see Setting up an HSV210-series controller pair using the OCP).

  • Showing the current password.

  • Changing a password (see Changing a password ).

  • Removing password protection (see Clearing a password ).

Changing a password

For security reasons, you may need to change a storage system password. Your password must contain eight alphanumeric characters consisting of any combination of the uppercase letters A through Z and the lowercase letters a through z.

Use the following procedure to change the password.
NOTE: Changing a system password on the controller requires changing the password on any HP Command View EVA with access to the storage system.
  1. Select a unique, eight-character alphanumeric password.

  2. From the default menus (Storage System Name or World Wide Node) displayed, press three times to display System Password .

  3. Press to display Change Password?

  4. Press Enter for yes.

    The default password, AAAAAAAA , is displayed.

  5. Press or to select the first character.

  6. Press to accept this character and select the next character.

  7. Repeat the process to enter the remaining password characters.

  8. Press Enter to enter the password and return to the default display.

Clearing a password

Use the following procedure to remove storage system password protection.
NOTE: Changing a system password on the controller requires changing the password on any HP Command View EVA with access to the storage system.
  1. Press four times to scroll to the System Password menu.

  2. Press to display Change Password.

  3. Press to scroll to Clear Password.

  4. Press to display Clear Password.

  5. Press Enter to clear the password. The Password cleared message will be displayed.

HSV controller cabling

All data cables and power cables attach to the rear of the controller. Adjacent to each data connector is a two-colored link status indicator.
  • When the green indicator is on, the link can communicate.

  • When the amber indicator is on, the link cannot communicate.

NOTE: These indicators do not indicate whether there is communication on the link, only whether the link can transmit and receive data.

The data connections are the interfaces to the disk drive enclosures or loop switches (depending on your configuration), the other controller, and the fabric. Fiber optic cables link the controllers to the fabric, and, if an expansion cabinet is part of the configuration, link the expansion cabinet drive enclosures to the loop switches in the main cabinet. Copper cables are used between the controllers (mirror port) and between the controllers and the drive enclosures or loop switches.
