Before you begin

Observe the following precautions when replacing the disk:

•Ensure you have a replacement part available before removing the

failed component. Removing a component impacts cooling within

the enclosure. Use a drive blank if a new drive is not available.

•HP recommends that the replacement drive matches the capacity and

speed of the original drive. For example, if the original drive was a

300 GB, 15K RPM drive, the replacement would be a 300 GB, 15K

RPM drive.

•Do not remove more than one disk at a time from the enclosure.

Doing so would impact cooling of the enclosure and may cause data

loss.

•Parts can be damaged by electrostatic discharge. Use proper anti-

static protection.

•Have a copy of the product user guide available for reference. You

can download a copy of the user guide from the product support

page on the HP website.

Types of disk failures

There are two types of disk failures:

•Hard failure: The disk is no longer functioning properly and has been

assigned a failed status. This type of failure is indicated by an oper-

ational state of (Failed) in HP P6000 Command View. The amber

fault status indicator on the disk is typically on.

•Impending failure: Although the disk is still functioning, errors have

been detected that indicate an impending failure. This type of failure

is not accompanied by a failed status.

CAUTION:

A disk with an impending failure will appear to be

operating normally in HP P6000 Command View,

and the fault light on the disk will not be on.

Therefore, it is important that you positively identify

the disk before performing the replacement. Work

with the HP Solution Center to ensure you identify

the correct disk for replacement.

Checking system redundancy

Before replacing a disk, check the redundancy status of the entire storage

system to ensure a disk can be removed without impacting data

availability.

1. Open HP P6000 Command View and click the icon of the storage

system you want to check (Figure 4).

Figure 4 Selecting a storage system

2. On the Initialized Storage System Properties window, click Check

Redundancy (Figure 5).

Figure 5 Checking redundancy

3. If the system is redundant, continue with Verifying component failure.

If the system is not redundant, information is displayed indicating

the cause of the lack of redundancy. See the HP P6000 Command

View online help to interpret the information that is displayed. In

this situation, work with your HP call center agent to determine how

to proceed.

CAUTION:

Do not proceed with the disk replacement until you are certain

the storage system is redundant.

Verifying component failure

Before replacing a disk, use the following methods to verify component

failure:

CAUTION:

If HP P6000 Command View does not present a status consistent

with the disk status indicators, or if HP P6000 Command View

or your system monitoring tool indicates multiple hardware

failures, contact HP support for assistance (http://www.hp.com/

support).

•Analyze any failure messages received. Error messages identify each

disk by its rack, enclosure, bay, and UUID (World Wide Name).

Record this information to assist you in identifying the correct disk

before replacing it.

The following is a sample of the disk identification information:

FRU List:

Storage System Name: EVA_1

Storage System World Wide ID: 5000-1FE1-0015-42A0

Disk Drive UUID: 2000-0000-871D-FE60

Drive Location ---

Enclosure ID: 8

Bay ID: 1

Rack Number: 0

NOTE:

The Disk Drive UUID corresponds to the disk Node

World Wide Name displayed in HP P6000

Command View.

•Check the disk status indicators (Figure 6 for Fibre Channel disks

and Figure 7 for SAS disks; Table 1 describes the LEDs). If a hard

failure has occurred, the amber indicator should be on solid.

•Check the disk status using HP P6000 Command View:

1. In the Navigation pane, select Storage system > Hardware >

Disk enclosure > Bay. Use the information from the error message

to guide you to the correct disk.

2. In the Content pane, select the Disk Drive tab.

3. Check the disk Node World Wide Name against the error

message UUID information recorded earlier to ensure you have

selected the correct disk (Figure 8).

Figure 8 Checking Node World Wide Name

4. Check the disk operational state. If a hard failure has occurred,

the operational state should be (Failed). A disk with an

impending failure indicates Good status until the condition of

the disk degrades enough to become a hard failure.

5. Verify that the Requested usage and Actual usage boxes display

Ungrouped (Figure 9).

Figure 9 Checking disk group status

CAUTION:

Both fields must display Ungrouped before you

remove the disk.

If fields display Ungrouped, continue with Step 7. If you must

ungroup the disk, continue with the following step.

Page 3

6. For an impending failure, you must ungroup the disk before you

remove it:

NOTE:

You should only ungroup one disk at a time. Before

you ungroup a disk, verify that leveling is not in

progress and that sufficient free space is available.

After you ungroup the disk, verify the status of the

disk group before continuing. For more information

about leveling and free space, see the Enterprise

Virtual Array configuration best practices white

paper for your array model.

a. Click Ungroup.

b. Click Ungroup in background.

CAUTION:

When selecting Ungroup in background, a

dialog box is displayed indicating the

Operation succeeded. This indicates that the

ungroup operation has been initiated. You can

monitor the progress of the ungroup on the Disk

Drive Properties window.

c. Click the Disk Drive tab and monitor the ungroup progress

in the Migration progress field (Figure 10).

Figure 10 Monitoring ungroup progress

When the ungroup is complete, continue with the next step.

NOTE:

The ungrouping process may take up to several

hours to complete. The time depends on the

capacity of the disk and the level of storage

system activity.

If, after attempting to ungroup the disk, the

Requested usage and Actual usage boxes do

not display Ungrouped or the Migration

progress box does not display 100%, contact

your HP-authorized service representative for

assistance.

7. Click Remove to prepare the disk for removal. The status

indicators on the disk will begin flashing to help you locate the

disk. You can now remove the disk as described in Removing

a hard drive.

Removing a disk drive

1. Determine the status of the disk drive from the hot-plug disk drive

LEDs.

2. Back up all data on the disk drive.

CAUTION:

To prevent improper cooling and thermal damage, do

not operate the storage enclosure unless all bays are

populated with either a disk drive or a blank.

3. Press the drive latch on the disk drive to unlatch the lever (1, Figure

11), and move the lever to the left (2).

Figure 11 Removing a disk drive

4. Pull the disk drive out of the drive bay (3).

Changing the Device Addition Policy

To prevent the storage system from automatically grouping a new disk

that may have the incorrect firmware on it, check the Device Addition

Policy and set it to manual if necessary:

1. In the HP P6000 Command View navigation pane, select the storage

system.

The Initialized Storage System Properties window opens.

2. Click System Options.

3. Select Set system operational policies.

4. If the Device Addition Policy is set to Automatic, change it to

Manual.

5. Click Save changes.

NOTE:

To return the Device Addition Policy to automatic, repeat this

procedure after you verify that the disk has the correct firmware

version.

Installing a disk drive

1. Insert the disk drive into the drive bay (1, Figure 12) until it clicks,

locking the drive. Push firmly on the front of the drive carrier to

ensure the drive is fully seated into the enclosure.

2. Rotate the drive lever to the right until it locks (2).

IMPORTANT:

When the drive is inserted and the enclosure is

powered, the drive LEDs flash for two seconds to

indicate that the drive is seated properly and receiving

power.

Figure 12 Installing a disk drive

3. As the drive begins to spin, be sure that the drive LEDs illuminate

one at a time and then turn off together to indicate that the system

has recognized the new drive.

In fault-tolerant configurations, allow the replacement drive to be

reconstructed automatically with data from the other drives. While

reconstruction is in progress, the online LED flashes.

Verifying proper operation

After replacing the disk, check the following to verify that the disk is

operating normally:

NOTE:

It may take up to 10 minutes for the component to display good

status.

•Check the disk status indicators (Table 1). The green indicator should

be on or flashing.

•Check the following using HP P6000 Command View:

•Navigate back to the component and check the operational state.

It should be (Good).

•Ensure the disk is running the correct firmware. Record the Model

number and the Firmware version of the disk (Figure 13). Check

the firmware version against the supported disk firmware in the

HP P6000 Enterprise Virtual Array Disk Drive Firmware Support

document, which is available at the following website:

http://www.hp.com/support/manuals

Click Disk Storage Systems under Storage, and then select the

appropriate product under P6000/EVA Disk Arrays.

If the disk is running an unsupported version of firmware, down-

load the correct firmware from the following website and install

it using the instructions included with the firmware file. Do not

add the disk to a disk group if it is running an unsupported firm-

ware version.

http://www.hp.com/support/evadiskfirmware

NOTE:

When downloading the firmware, use the disk

model number to locate the correct firmware file.

If you have difficulty locating the correct firmware,

contact your HP-authorized service representative

for assistance.

Figure 13 Checking model number and firmware version

Adding the disk to a disk group

After replacing the disk, add it to a disk group. The disk is typically

added back into its original disk group.

1. In the navigation pane, select Storage system > Hardware >

Disk Enclosure > Bay.

2. In the content pane, select the Disk Drive tab.

3. Click Group to initiate the process for adding the disk to a disk

group.

Operation Successful is displayed indicating the disk is now

grouped and leveling has been initiated. The storage system begins

immediately using the disk.

NOTE:

If the Device Addition Policy is set to automatic, the disk is

automatically added to a disk group. In this case the Group

option will not be available.

Returning the failed component

Follow the return instructions provided with the new component.
