Preparation procedures

System power to the MSA1500 cs does not shut off completely with the power switch. The

two positions of the front panel power switch should be considered as ON and STANDBY,

rather than ON and OFF. The STANDBY position removes power from most of the electronics

and the drives, but portions of the power supply and some internal circuitry remain active. To

remove all power from the system, you must disconnect the power cord from the storage

system. In systems with multiple power supplies, you must disconnect all the power cords to

remove power completely from the system.

WARNING: To reduce the risk of electric shock or damage to the equipment, disconnect

power from the storage system by unplugging all power cords from either the electrical

outlet or the MSA1500 cs.

Note: Before removing any serviceable part, determine whether the part is hot-pluggable or

non-hot-pluggable. Hot-pluggable devices in the MSA1500 cs include the fan modules, power

supplies, I/O modules and the MSA1000 controllers.

Hot-pluggable parts

If the part is hot-pluggable, a power shutdown of the device in not required for replacement of

the part. Hot-pluggable devices in the MSA1500 cs include the power supplies, fan modules,

SCSI I/O modules, Fibre Channel I/O modules, and MSA1000 Controllers.

WARNING: Before replacing a hot-pluggable component ensure that steps have been

taken to prevent loss of data.

Non-hot-pluggable parts

If the part is non-hot-pluggable, the MSA1500 cs must be powered down. Non-hot-pluggable

parts include the 2U chassis, and the power switch.

WARNING: To reduce the risk of personal injury or damage to the equipment, the

installation of options other than hot-plug power devices should be performed only by

individuals who are qualified in servicing computer equipment and trained to deal with

handling.

■Obtain adequate assistance to lift and stabilize the product during installation or

removal.

■Remove all pluggable power supplies and modules to reduce the weight of the product.

■Always load the heaviest item first, and load the rack from the bottom up. This makes the

rack “bottom-heavy” and helps prevent the rack from becoming unstable.

■Extend the leveling jacks to the floor.

■Rest the full weight of the rack on the leveling jacks.

■Attach the stabilizing feet to the rack if it is a single-rack installation.

■The racks are coupled in multiple-rack installations.

■Fully extend the bottom stabilizers on the equipment. Be sure that the equipment is

properly supported/braced when installing options and boards.

■Be careful when sliding the unit into the rack. The slide rails could pinch your fingertips.

■Ensure that the rack is adequately stabilized before extending a component outside the

rack. Extend only one component at a time. A rack may become unstable if more than

one component is extended for any reason.

■Do not attempt to move a fully loaded equipment rack. Remove equipment from the rack

before moving the rack.

■At least two people are needed to safely unload the rack from the pallet. An empty 42U

rack weighs 115 kg (253 lb), is over 2.1 meters (7 ft) tall, and may become unstable

when being moved on its casters. Do not stand in front of the rack as it rolls down the

ramp from the pallet; handle it from the sides. Stabilize the device by keeping the unit on

the rails.

WARNING: Because the rack allows stacking of computer components on a vertical rather

than horizontal plane, ensure that precautions have been taken to provide for rack stability

and safety. It is important to follow these precautions providing for rack stability and safety,

and to protect both personnel and property. Heed all cautions and warnings throughout the

Replacing the MSA1000 Controller

The following steps detail how to replace a failed MSA1000 Controller.

Note: Before replacing your controller, follow these guidelines: If your system is equipped with a

single controller, and this controller fails, it is recommended that the old cache module be migrated

to a new controller. This is done to complete the disk writes that may have been trapped in the

controller’s cache. If an expand process is occurring, a dual controller system will transition into a

non-redundant state. If a controller failure occurs during an expand process, it is required that the

old cache module be migrated to the replacement controller to complete the expand process. If this is

not done, the array contents will be invalid.

Note: The MSA1000 Controller is hot-pluggable and the unit does not need to be powered down

in order to replace them.

1. Complete the preparation procedures. See the “Preparation procedures” on page 20 of this

chapter.

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

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

MSA1000 Controller display

Each array controller in a MSA1500 cs 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.

The display module consists of the following components:

■A two line, twenty column display text display window

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

■Two status indicator lights

Controller display messages

The display module is capable of holding up to 100 messages. After this maximum size is

reached, older messages are 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 MSA1500 cs chassis.

■Box 2 is the storage enclosure attached to SCSI port A of the MSA1500 cs.

■Box 3 is the storage enclosure attached to SCSI port B of the MSA1500 cs.

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 chapter.

An amber indicator to the left of the LCD display is turned on when an error message is

currently displayed. This indicator is 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 backward and viewing all error messages, the indicator will

reset and light 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 chapter.

The amber indicator to the left of the LCD display is off whenever an informational message is

currently being viewed unless an unviewed error message was previously sent to the display

module. By scrolling backward 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 a situation that allows user

input. The user can select from a number of choices. If the user does not select one of the

choices in a set amount of time, the system will select the default setting. 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 chapter.

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.

Scrolling

Older messages can be viewed by scrolling backward using the up navigation button (with the

up arrow on it). Messages that are more recent can be viewed by scrolling forward using the

down navigation button (with the down arrow on it). The last message can be viewed by

pressing the left navigation button. When a new message is sent to the LCD, the display shows

that message and ignores any previous scrolling position. This new message is now the most

recent message available.

Diagnostics

55Modular Smart Array 1500 cs Maintenance and Service Guide

Deleting messages

The currently displayed message can be deleted from the display module by pressing the left

navigation button and the right navigation button at the same time.

Redundancy link light

There is a green indicator to the left of the LCD display that is lit when two array controllers

are inserted into the MSA1500 cs with controller redundancy enabled. The indicator is not lit

if only one array controller is inserted or if the array controllers are not redundant due to some

type of failure.

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 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

In order for a MSA1500 cs 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 MSA1500 cs 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. On initial power up, the controller in the right slot is considered the primary

controller and the version of firmware on that controller is cloned. If a failed controller is

replaced, the controller still in operation is considered the primary controller and the version

on that controller is cloned.

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 is updated is already operating and

processing I/O, then it will not be reset. The MSA1500 cs will not enter redundant operation

and an appropriate message will be shown on the display. After the MSA1500 cs 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.

Note: The system power in the MSA1500 cs does not shut off completely with the power switch.

STANDBY removes power from most of the electronics and the drives, but portions of the power

supply and some internal circuitry remain active. To remove the power completely, disconnect all

power cords from the equipment.

Power supply

The power supply uses a single bi-color LED to indicate status. This LED can be illuminated

with either a green or amber color. The green indicator on the power supply assembly is on

when the power supply is operational. When the power supply experiences a fault, the power

supply indicator turns amber. If the power supply indicator is off, AC power is not present.

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.

Electrostatic Discharge

94 Modular Smart Array 1500 cs Maintenance and Service Guide

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.
