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.

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. |

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. |
Press
three times to scroll to the Shutdown Options menu.
Press
to display Restart.
Press
to scroll to Power Off.
Press
to select Power Off.
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. Press
three times to scroll to the Shutdown Options menu.
Press
to select Restart. Press
to display Restart system?
.
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. Press
three times to scroll to the Shutdown Options menu.
Press
to select Restart. Press
twice to display Uninitialize System Press
to display Uninitialize? Select Yes
and press Enter
. The system is now uninitialized.
Password options
The password entry options are:
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. |
Select a unique, eight-character alphanumeric password.
From the default menus (Storage System Name or World Wide Node) displayed, press
three
times to display System Password
.
Press
to display Change Password?

to accept this character and select the next character.
Repeat the process to enter the remaining password characters.
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. |
Press
four times to scroll to the System Password menu.
Press
to display Change Password.
Press
to scroll to Clear Password.
Press
to display Clear Password. Press Enter
to clear the password.
The Password cleared
message will be displayed.
Setting up a controller pair using the OCP
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.
