CX3 UltraScale™ Series and CX SeriesReplacing a Disk Module

To replace a disk module in a storage system, you must use the DiskReplacement Utility. This utility checks the storage system for disk modulesthat need replacing, and if any need replacing, it tells you how to replacethem.

This document describes how to use the utility, which is part of theNavisphere® Service Taskbar (NST). The NST is available from thePowerlink® website (http://Powerlink.EMC.com) on the CLARiiON®Tools page.

Before you start

The Navisphere Service Taskbar (NST) must run on a Windows hostthat is:

❑ Running a supported operating system version. For supportedversions, refer to the EMC Navisphere Service Taskbar Release Notes(P/N 300–003–690).

❑ Connected to the Internet and is on the same LAN as themanagement ports on your storage system.

❑ Running Java Runtime Environment (JRE). For supported versions,refer to the EMC Navisphere Service Taskbar Release Notes. If you donot install the correct version prior to downloading NST, the NSTsetup wizard gives you the option of installing it for you.

2 Replacing a Disk Module

Handling field replaceable units (FRUs)

This section describes the precautions that you must take and thegeneral procedures you must follow when removing, installing, andstoring any field replaceable unit (FRU).

Power issues and FRUs

Your storage system is designed to be powered on continuously. Mostcomponents are hot swappable; that is, you can replace or install thesecomponents while the storage system is running. Front bezels shouldalways be attached and each compartment should contain a FRU orfiller panel to ensure EMI compliance and proper air flow over theFRUs.

You should not remove a faulty FRU until you have a replacementavailable.

When you replace or install FRUs, you can inadvertently damagethe sensitive electronic circuits in the equipment by simply touchingthem. Electrostatic charge (ESD) that has accumulated on your bodydischarges through the circuits. If the air in the work area is very dry,running a humidifier in the work area will help decrease the risk ofESD damage. Follow the procedures below to prevent damage to theequipment.

Read and understand the following instructions:

Provide enough room to work on the equipment. Clear the worksite of any unnecessary materials or materials that naturally buildup electrostatic charge, such as foam packaging, foam cups,cellophane wrappers, and similar items.

Do not remove replacement or upgrade FRUs from their antistaticpackaging until you are ready to install them.

Before you service a storage system, gather together the ESD kitand all other materials you will need. Once servicing begins, avoidmoving away from the work site; otherwise, you may build up anelectrostatic charge.

An ESD wristband is supplied with your storage system. To use it,attach the clip of the ESD wristband (strap) to any bare (unpainted)metal on the storage system; then put the wristband around yourwrist with the metal button against your skin.

Replacing a Disk Module 3

Use the ESD kit when handling any FRU. If an emergency arisesand the ESD kit is not available, follow the procedures in the“Emergency procedures (without an ESD kit)” section.

Emergency procedures (without an ESD kit)

In an emergency when an ESD kit is not available, use the followingprocedures to reduce the possibility of an electrostatic dischargeby ensuring that your body and the subassembly are at the sameelectrostatic potential.

These procedures are not a substitute for the use of an ESD kit. Followthem only in the event of an emergency.

Before touching any FRU, touch a bare (unpainted) metal surface ofthe cabinet or storage system.

Before removing any FRU from its antistatic bag, place one handfirmly on a bare metal surface of the storage system, and at thesame time, pick up the FRU while it is still sealed in the antistaticbag. Once you have done this, do not move around the room ortouch other furnishings, personnel, or surfaces until you haveinstalled the FRU.

When you remove a FRU from the antistatic bag, avoid touchingany electronic components and circuits on it.

If you must move around the room or touch other surfaces beforeinstalling a FRU, first place the FRU back in the antistatic bag. Whenyou are ready again to install the FRU, repeat these procedures.

Downloading and installing the Navisphere Service Taskbar

Download the Navisphere Service Taskbar (NST) from thePowerlink CLARiiON Tools page for your storage system.

To access the CLARiiON Tools page, use the Navigator drop-down menu atthe top right of the Powerlink home page.

1. On the CLARiiON Tools page on the Powerlink website, selectyour CLARiiON system.

2. Select Navisphere Service Taskbar and select the option to save thesoftware to your host or management station.

3. In the folder where you saved the NST, double-click thesetup_NST.exe file, and if necessary, click Run to start theinstallation wizard.

4. Follow the instructions that appear.

After you accept the license agreement, the wizard verifies thatthe server is running the supported Java Runtime Environment(JRE) version.

If the server is running an earlier version of the JRE, select Yeswhen asked if you want to continue with the installation.

The installation wizard prompts you to download and installthe later version of the JRE from the Sun website.

If the server is running a later version of the JRE, the installationwizard asks if you want to continue with the installation.

Select Yes to continue or No to quit the installation.

Important: If you select Yes, the NST may not work properly witha later JRE version. If you select No, and manually remove the laterversion of the JRE, other applications that require this version maynot work properly.

5. When the installation is complete, click Done.

Replacing a Disk Module 5

Running the Disk Replacement wizard

! CAUTION

Disk modules are extremely sensitive electronic components. Alwayshandle a disk module gently, and observe the following guidelines:

Always wear a properly attached ESD wristband when removingor replacing a disk module.

Disk modules are sensitive to the extreme temperaturessometimes encountered during shipping. We recommend thatyou leave new disk modules in their shipping material andexpose the package to ambient temperature for at least four hoursbefore attempting to use the new modules in your system.

When removing a disk module, pull the module part way out ofthe slot, then wait 30 seconds for the drive to spin down beforeremoving it.

When installing multiple disks in a powered up system, wait atleast 6 seconds before sliding the next disk into position.

Place modules on a soft, antistatic surface, such as anindustry-standard antistatic foam pad or the container used toship the module. Never place a disk module directly on a hardsurface.

Never hit modules, stack modules, or allow them to tip over orfall.

Avoid touching any exposed electronic components and circuitson the disk module.

Do not remove a faulty disk module until you have a replacementmodule (with the same part number) or a filler module available.The part number (PN005xxxxxx) appears on the top or bottom ofthe module. A replacement disk module should have the sameformat (bytes per sector) and the same capacity (size and speed)as the module it is replacing.

1. Start the Navisphere Service Taskbar by doing either one of thefollowing:

6 Replacing a Disk Module

Verifying the operation of a new or replaced part using NavisphereManager

1. Start Navisphere® Manager for the storage system by entering theIP address in a browser window.

2. On the management workstation, start Navisphere Manager forthe storage system:

a. In a browser window, enter the IP address of the storage system.

b. Log in to Navisphere Manager with username cdlsupport andpassword wabisabi, and select global from the drop-downmenu for scope.

c. Click OK.

3. In the Navisphere Manager Storage tree, locate the icon for thestorage system in which you installed or replaced the part, expandthe storage-system icon, and select the Physical icon.

4. Expand the enclosure in which you installed or replaced the part,and navigate to the part.

5. Verify that the part is in the enclosure and that it is not faulted.

6. Verify that there are no trespassed LUNs on either storage processor(SP).

Replacement disk rebuilding

A replacement disk is rebuilt by restoring data to it from the RAIDgroup. Depending on the size of the disk, how much data is on thedisk, and whether I/O is running during the rebuild, this processcan take from a few minutes to many hours. You can determine theprogress of the rebuild process from Navisphere Manager by viewingthe properties for a LUN containing the replacement disk. The PercentRebuilt entry on the LUN Properties dialog box displays either thepercentage of the rebuild completed during the rebuild process and100% when the process is complete.
