MSA1000 Controller

Components

The MSA1000 Controller is a drive array controller specifically designed for installation in the MSA1000. The MSA1000 comes equipped with one MSA1000 Controller installed. An additional controller for redundancy can be purchased separately.

To ensure uninterrupted service, two copies of the controller firmware are stored in Read Only Memory (ROM) on the controller. See the “Recovery ROM” and “ROM Cloning” sections for more information.

Additional information about the following topics is included in this section:

■ MSA1000 Controller Display

■ Array Accelerator (Battery-backed Cache)

MSA1000 Controller

MSA1000 Controller Display

Each array controller in an MSA1000 contains an integrated Liquid Crystal Display (LCD). This module is used for displaying informational and error messages, showing the status of the module, and for providing user input when required. Traditional Power-On Self-Test (POST) messages issued by PCI-based array controllers have been combined with runtime event notification messages to create a new set of controller display messages.

Array Accelerator (Battery-backed Cache)

The Array Accelerator is a high-performance, upgradeable 256-MB SDRAM DIMM read/write battery-backed cache that can increase performance in database and fault-tolerant configurations. It performs both protected posted-write caching and read-ahead caching, allowing data to be accessed much faster than from disk storage.

In protected posted-write caching, data is written to the cache memory on the Array Accelerator rather than directly to the drives. Later, when the MSA1000 storage system is idle, the controller writes the cached data to the drive array.

The read-ahead cache detects sequential accesses to the array, reads ahead data, and stores the data in the cache until the next read access arrives. If the data is of a sequential nature, the data can be loaded immediately into memory, avoiding the latency of a disk access.

If the MSA1000 Controller fails before cached data is stored on the disk, the Array Accelerator and its integrated batteries may be removed from one MSA1000 Controller and installed on a replacement controller. Any data in the Array Accelerator that has not been written to the hard drive will be transferred to the replacement MSA1000 Controller.

Array Accelerator Features

MSA1000 Controller

Other features of the Array Accelerator:

■ Mounted on a removable daughterboard (allows stored data to be moved to

another controller if the original controller fails)

■ Backed up with replaceable batteries

■ Upgradable to 512 MB (256 MB per controller)

■ Adjustable read/write ratio - usually set during array configuration but can be

changed at any time

■ 16-bit Error Checking and Correcting (ECC) SDRAM memory

ECC detects and corrects all single-bit memory errors. It also detects all two-bit memory errors in any position, and most three- and four-bit memory errors in a single SDRAM. With ECC, an entire memory chip can also fail without data loss. This provides a high level of data integrity by ensuring the correction of common memory errors without affecting performance.

13MSA1000 Controller User Guide

MSA1000 Controller

Array Accelerator Batteries

The Array Accelerator has two rechargeable and replaceable Nickel Metal Hydride (NiMH) battery packs. Under normal operating conditions, these should last for three years before replacement is necessary. They are continuously recharged via a “trickle” charging process whenever the MSA1000 storage system is powered on.

The battery packs protect data on the Array Accelerator against equipment failure or power outage for up to four continuous days.

Note: Temperature, age, and cache size may affect battery life.

This also applies if the Array Accelerator is removed from the MSA1000 Controller. When power is restored to the MSA1000 storage system, an initialization process writes the preserved data to the disk drives. This is particularly important for data that has been cached by a posted-write operation, but has not yet been written to the hard drives.

Note: The batteries on a new MSA1000 Controller may be discharged when the

board is first installed. In this case, a Power-On Self-Test (POST) message will be displayed on the controller display panel when the controller is powered on, indicating that the Array Accelerator is temporarily disabled. No action is required on your part, since the internal circuitry will automatically recharge the batteries. Recharging the batteries can take up to 4 hours. The MSA1000 Controller will function properly during this time, although without the performance advantage of the Array Accelerator. When the batteries are charged to 90 percent of their capacity, the Array Accelerator is automatically enabled.

Depending on the status of the array accelerator, including a low battery charge, informational or error messages may be displayed on the controller’s LCD panel. For a listing of cache module LCD messages, see the definitions for LCD messages 60 through 79 in the “Controller Display Messages” chapter.

Replacing the MSA1000 Controller Cache

Caution: It is important to follow these instructions when replacing

components in the MSA1000. If the procedure is done improperly, it is possible to lose data or damage equipment. Refer to Appendix B, “Electrostatic Discharge,” for important information on using the proper procedures.

Note: If your system is equipped with a single controller, and you must replace the

controller cache, you must power down the system first. If your system is equipped with two controllers, and you want to replace a failed cache module with another of the same size, you can replace the module while the system is running. If your system is equipped with two controllers, and you are replacing the cache module with a module of a different size, you must power down the system first, and then change the cache module on both controllers at the same time.

1. Press the controller’s thumb latch and pull the latch handle towards you 1. See Figure 2.

2. Remove the MSA1000 Controller by pulling it straight out of the chassis 2.

Recovery ROM and ROM Cloning

Recovery ROM

Each MSA1000 Controller contains ROM (Read-Only Memory), which holds the firmware that operates the controller. The Recovery ROM feature stores two complete firmware images in the ROM: one active image and one backup image. When the controller is powering up, it checks both firmware images to ensure they are valid. If either one is not, the valid image will be copied on top of the invalid image to correct it. This is referred to as auto-flashing. All of this functionality is done automatically by the controller and does not require any user intervention.

ROM Cloning

Note: For an MSA1000 to operate in a redundant controller configuration, it must

contain two controllers that are executing the same version of firmware. During power up (or if an optional controller is hot-plugged while the MSA1000 is already operating) the firmware versions on both controllers are compared. If they are not the same, then the ROM Cloning feature will attempt to copy one version of firmware onto the other controller. After the copy has been completed, the controller that was modified will be automatically reset. Once the reset controller has powered up the two controllers should then start redundant operation. All of this functionality is done automatically by the controllers and does not require any user intervention.

MSA1000 Controller

The determination as to which firmware version will be used is based on the following criteria:

■ If the MSA1000 is being powered up with both controllers inserted, then the

most recent version of firmware will be used regardless of which controller it resides.

■ If the MSA1000 is already operating and an optional controller is

hot-plugged, then the version of firmware that is on the original (non-hot-plugged) controller will be used regardless of its version. This ensures that any host initiated I/O to the controller is not interrupted.

There is the possibility that a specific version of firmware may not be compatible with certain hardware revisions of a controller. In this scenario, the most recent firmware version that is compatible with both controllers will be copied to the controller with the incompatible firmware version. However, if the controller that

23MSA1000 Controller User Guide

MSA1000 Controller

is updated is already operating and processing I/O, then it will not be reset. The MSA1000 will not enter redundant operation and an appropriate message will be shown on the display. After the MSA1000 has been shutdown and powered back on, the controllers will then be able to enter redundant operation. On a subsequent power cycle, both controllers will enter redundant mode.

MSA1000 Controller Indicators

During normal runtime, the MSA1000 Controller has 18 indicators that indicate activity or malfunction of the controller. They are labeled 0-17, as shown in the following figure. The table that follows describes the purpose and function of each indicator.

Replacing the MSA1000 Controller

If an MSA1000 Controller is failing, informational or error messages will be displayed on the LCD panel of that controller, depending on the condition.

The following steps detail how to replace a failed MSA1000 Controller but can also be used to re-seat the controller.

Note: Redundancy is supported during a hard drive expansion, migration, or

extension process and during regular drive rebuilds.

Note: Replacement MSA1000 Controllers include a new cache module. Remove this

Updating the Controller Firmware

To load the latest version of the firmware for the MSA1000 Controller, go to the HP website at page, select the Software, Firmware & Drivers option.

Note: All supported operating systems obtain MSA1000 Controller firmware upgrades

from the HP website.

Installation instructions are available on the website. You can use several methods to find out the version of the controller firmware you

are currently running:

■ On the MSA1000 Controller LCD panel, use the arrow keys to scroll

backwards through the messages. Each time the MSA1000 storage system is restarted, the first message that is

displayed includes the firmware version.

■ In the CLI, use the SHOW VERSION command.

■ In the ACU, highlight the controller and view the details.

Controller Display Messages

Each array controller in an MSA1000 contains an integrated display. This module is used for displaying informational and error messages, showing the current status of the module, and for providing user input when required. Traditional Power-On-Self-Test (POST) messages issued by PCI-based array controllers have been combined with runtime event notification messages to create a new set of controller display messages.

The display module consists of the following components:

■ A two-line, twenty-column display text display window

■ Four push buttons arranged in a circular “pie” shape

■ Two status indicator lights

Controller Display Messages

About the LCD Messages

The display module is capable of holding up to 100 messages. Once this maximum size has been reached, older messages will be removed to make room for newer ones. Messages can be of three types: error, informational, and user input.

The display message may specify a box number. The following box numbers are defined.

■ Box 1 is the MSA1000 chassis.

■ Box 2 is the storage enclosure attached to SCSI port A of the MSA1000.

■ Box 3 is the storage enclosure attached to SCSI port B of the MSA1000.

Error Messages

Error messages indicate that a problem has occurred and may require user action to correct it. A complete list of possible messages and their meanings is contained in this appendix.

An amber indicator to the left of the display text display window will be turned on when ever an error message is currently being viewed. This indicator will also be turned on if an error message was sent to the display module but has not been viewed because non-error type messages were sent to the display module afterwards. By scrolling backwards and viewing all error messages, the indicator will return to only lighting up when currently on an error message.

Informational Messages

Informational messages indicate non-critical changes in the system that are provided as feedback to the user. A complete list of possible messages and their meanings is contained in this appendix.

The amber indicator to the left of the display text display window will normally be turned off whenever an informational message is currently being viewed unless an unviewed error message was previously sent to the display module. By scrolling backwards and viewing all error messages, the indicator will return to only lighting up when currently on an error message.

User Input Messages

User input messages indicate that the system has encountered an issue that can be handled in two different ways. It allows the user to either choose which way to handle the issue or it will default to a standard choice after a set period of time.

User Input

Controller Display Messages

These user input messages will only occur during system power on and not during run time. A complete list of possible messages and their meanings is contained in this appendix.

The amber indicator to the left of the display text display window will blink on and off when a user input message is currently being viewed and is available for input. If the user has not provided input within the time-out period, the message will remain but the indicator will stop blinking.

Older messages can be viewed by scrolling backwards using the up push button (with the up arrow on it). Messages that are more recent can be viewed by scrolling forwards using the down push button (with the down arrow on it). The last message can be viewed by pressing the left button. When a new message is sent to the LCD, the display will show that message and ignore any previous scrolling position. This new message is now the most recent message available.

User input messages will allow the user two options, which are selected by either pushing the left push button (with the left arrow on it) or the right push button (with the right arrow on it). The meaning of each button will be defined in the display text display window.

Deleting Messages

The currently displayed message can be deleted from the display module by pressing the left push button and the right push button at the same time.

Redundancy Link Light

There is a green indicator to the left of the display text display window that will be lit when two array controllers have been inserted into the MSA1000 and they have enabled controller redundancy. The indicator will not be lit if there is only one array controller inserted or if the array controllers are not redundant due to some type of failure.

Note: You must have redundant cables connected to enable redundancy.

Electrostatic Discharge

To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

■ Avoid hand contact by transporting and storing products in static-safe

containers.

■ Keep electrostatic-sensitive parts in their containers until they arrive at

static-free workstations.

■ Place parts on a grounded surface before removing them from their

containers.

■ Avoid touching pins, leads, or circuitry.

■ Always make sure you are properly grounded when touching a static-sensitive

component or assembly.

67MSA1000 Controller User Guide

Electrostatic Discharge

Grounding Methods

There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

■ Use a wrist strap connected by a ground cord to a grounded workstation or

computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

■ Use heel straps, toe straps, or boot straps at standing workstations. Wear the

straps on both feet when standing on conductive floors or dissipating floor mats.

■ Use conductive field service tools.

■ Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an Authorized HP Reseller install the part.

Note: For more information on static electricity, or assistance with product installation,

contact your HP Authorized Reseller.
