Overview

MSA1000 Controller display

Each controller 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.

Overview

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 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

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.


15

Overview

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 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 messages 60

through 79 in “ Controller Display Messages ” on page 31.

Overview

Controller firmware

Each MSA1000 Controller contains Read-Only Memory (ROM), which holds the firmware that operates the controller.

When operating in a redundant controller configuration, the MSA1000 or

MSA1500 cs must contain two controllers executing the same firmware version.

Automatic firmware recovery

Two firmware images are stored in the ROM of each controller: one active image and one backup image.

Each time the system is powered on or restarted, the active and the backup images on the controller are checked to ensure they are valid. If one of the images is not valid, the valid image is automatically copied on top of the invalid image. This functionality does not require any user intervention.

Redundant-controller rirmware cloning

Each time a system with two controllers is powered on, restarted, or if a second controller is hot-plugged in a single-controller configuration, the firmware versions on the controllers are compared. If the firmware versions on the controllers are not the same, the system prompts to clone the firmware from the active controller onto the standby controller as follows:

CLONE FIRMWARE ? ‘<‘ = NO, ‘>’ = YES

If a “no” response is entered or a response is not made to the prompt within 60 seconds, the firmware is not cloned and power to the standby controller is disabled. The system will operate from from one controller in a non-redundant mode until the firmware on both controllers is the same.

If a “yes” response is entered, the following messages are displayed while the contoller is updated and automatically restarted:

ROM CLONING STARTED

ARRAY CONTROLLER RESTARTING

MSA1X00 STARTUP COMPLETE

The two controllers should now operate in redundant mode.

Note: Cloning is not possible in single-controller configurations.

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; they 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 Controllers include a new cache module. Remove this new module from the replacement Controller and replace it with the cache module from the failed controller. Using the same cache module will complete the disk writes that may have been trapped in the controller’s cache. See “

Replacing the MSA1000 Controller cache ”

for procedural instructions.

1. Press the controller’s thumb latch and pull the latch handle toward you 1.

2. Remove the MSA1000 Controller by pulling it straight out of the chassis 2, as illustrated in Figure 3 .

Controller Display Messages

3

Each array controller contains an integrated display panel. This panel 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 is capable of holding up to 100 messages. After this maximum size has been reached, older messages are automatically removed to make room for newer ones.

LCD message types

Messages can be of three types: error, informational, and user input.

See “ LCD message descriptions ” on page 34for a complete list of messages and

their meanings.

Error messages

Error messages indicate that a problem has occurred and may require user action to correct it.

An amber indicator to the left of the display text display window will be turned on when ever an error message is 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.

After 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.

The amber indicator to the left of the display text display window will normally be turned off whenever an informational message is being viewed unless an unviewed error message was previously sent to the display module.

After 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 choose which way to handle the issue or it will default to a standard choice after a set period of time. These input messages only occur during system power on and not during run time.

The amber indicator to the left of the display text display window will blink on and off when a user input message is being viewed and is available for input.

Press the left or right button on the LCD panel to respond to the prompt. If the user has not provided input within the time-out period, the message will remain but the indicator will stop blinking.

32



Responding to LCD messages

When a new message is sent to the LCD, the display will automatically show that message and ignore any previous scrolling position.

The display panel consists of a two-line, twenty-character text display window and four push buttons arranged in a circular “pie” shape. The push buttons are used to scroll through the messages, respond to prompts, and delete messages, as described in the following illustration and table.

Electrostatic Discharge

B

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.


69

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.
