About This Document

This document describes the procedure for replacing the Fibre Channel

disk drive used in the EVA products.

Before you begin

Observe the following precautions when replacing the disk.

CAUTION:

Make sure you have a replacement part available before

removing the failed component. Removing a component impacts

cooling within the enclosure.

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

Doing so will impact cooling of the enclosure and may cause

data loss.

Parts can be damaged by electrostatic discharge. Use proper

anti-static protection. Refer to the documentation that shipped

with your system for additional information.

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 web site.

Disk replacement video

To assist you in replacing the disk, a replacement video has been

produced. You can view the video at the following web site. The same

procedure is used for EVA3000/5000 and EVA4000/6000/8000

products.

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

operational state of Failed in Command View EVA. The amber

fault status indicator on the disk is typically on.

Page 1

•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 Command View EVA, and the fault light on the disk

will not be on. Therefore, it is important the disk be positively

identiﬁed before performing the replacement. Make sure you

work with the HP Solution Center to ensure you identify the correct

disk for replacement.

Checking system redundancy

Before replacing a disk, you should check the redundancy status of

the entire storage system to ensure a disk can be removed without

impacting data availability.

CAUTION:

Do not proceed with the disk replacement until you are certain

the storage system is redundant.

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

system you want to check. See Figure 1.

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

Redundancy.SeeFigure 2.

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. Refer to online help for help

in interpreting the information displayed. In this situation, work

with your HP call center agent to determine how to proceed.

Figure 2 Checking redundancy

Verifying component failure

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

component failure:

CAUTION:

IfCommandViewEVAdoesnotpresentastatusconsistentwith

that of the disk status indicators, or if Command View or Instant

Support Enterprise Edition (ISEE) indicates multiple hardware

failures, contact HP support for assistance. The HP support web

site is located at http://www.hp.com/support

•Analyze any failure messages you may have received from system

monitoring (ISEE). 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 Command View.

•Check the disk status indicators.SeeFigure 3.Ifahardfailurehas

occurred, the Fault indicator should be On.

•CheckdiskstatususingCommandView EVA:

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

Rack>Diskenclosure>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. See Figure 4.

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 and will continue to do

so until the condition of the disk degrades enough to become

a hard failure.

5. Check the following conditions.

CAUTION:

The following conditions must all have the indicated states

before the disk is removed.

• Requested usage - Ungrouped. See Figure 6.

• Actual usage - Ungrouped. See Figure 6.

If all the above conditions are met, continue with Step 7.Ifthe

disk needs to be ungrouped, continue with the following step.

NOTE:

If the above conditions are not met after attempting to

ungroup the disk, contact your HP-authorized service

representative for assistance.

6. For an impending failure, it will be necessary to ungroup the

disk as follows before it can be removed.

a. Click Ungroup.

b. Click Ungroup in background.

CAUTION:

When selecting Ungroup in background, a dialog 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 page.

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

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

• If you are running XCS v6.000 or later, monitor the

Migration progress ﬁeld. See Figure 5.

• If you are running an earlier version of XCS or any

version of VCS, monitor the Requested usage ﬁeld and

the Actual usage ﬁeld. The status of both ﬁelds will

indicate Ungrouped when the process is complete.

NOTE:

The ungrouping process may take up to several hours to

complete. The time depends on the capacity of the disk

and thelevelofstoragesystemactivity.

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

indicators on the disk will begin ﬂashing to help you locate
