Shelf

Disk Shelf Maintenance Procedures

This section provides procedural details for customer replaceable units (CRUs) of any disk shelf in the Sun ZFS Storage 7000 family of products. Refer to Disk Shelf Overview for component specifications and diagrams.

Prerequisites

• Read the information in the overview section for your controller and become familiar with the replaceable parts of the system:

• 7120 Overview

• 7420/7720 Overview

• 7700 Overview

• Follow the instructions in the Electrostatic Discharge Precautions section.

Legacy platform overviews for 7110, 7210, 7310, 7410, and J4400/J4500 Disk Shelf are provided in those sections of the Sun Storage 7000 Unified Storage System Service Manual.

Safety Information

Follow all Sun cautions, warnings, and instructions marked on the equipment and described in Important Safety Information for Sun Hardware Systems located at http://dlc.sun.com/pdf/816-7190-12/816-7190-12.pdf.

Electrostatic Discharge Precautions

• Remove all plastic, vinyl, and foam material from the work area.

• Wear an antistatic wrist strap at all times when handling any CRU.

• Before handling any CRU, discharge any static electricity by touching a grounded surface.

• Do not remove a CRU from its antistatic protective bag until you are ready to install it.

• After removing a CRU from the chassis, immediately place it in an antistatic bag or antistatic packaging.

• Handle any card that is part of a CRU by its edges only and avoid touching the components or circuitry.

• Do not slide a CRU over any surface.

• Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.

Tasks

Shelf Tasks

Replacing a Drive

The shelf drives are hot-swappable and may be replaced without removing power from the shelf. The replacement drive must be of the same capacity and type as the drive to be replaced. To avoid possible data loss when removing non-faulted drives, label each drive with the number of the slot from which it was removed and reinstall each drive into the same slot.

Faulted drives are indicated by an amber LED. Go to the Maintenance > Hardware section of the BUI and double click the shelf thumbnail to view Details for HDDs or to turn on the locator LED.

1. Locate the failed disk drive at the front of the chassis.
2. Press the release button in and to the right to release the ejection lever.
3. Pull the ejection lever fully open to unlock and partially eject the drive from the chassis.
4. Grasp the middle of the drive body and pull it toward you to remove it from the chassis.
5. Ensure the new drive ejection lever is in the fully extended position.
6. Align the new drive with the open slot and slide the drive into the disk chassis.
7. Push the drive into the chassis slot until the ejection lever engages the chassis connectors and begins to swing closed.
8. Press the ejection lever closed until it locks in place to seat the drive and lock it into the chassis. The Activity LED with be steady green to indicate a ready state.
9. Go to the Maintenance > Hardware screen of the BUI. Click for the controller and then click HDD to verify that the icon is green for the newly installed disk.

Replacing a Power Supply

The power supplies are hot-swappable and can be replaced without removing power from the system. The power supplies can produce high energy hazard and should only be replaced by instructed individuals with authorized access to the equipment. Failed power supplies are indicated by an amber LED on the rear panel, see the Shelf Rear Panel illustration. Go to the Maintenance > Hardware screen of the BUI. Double click the shelf and then click PSU to view details or to turn on the locator LED.

1. Locate the chassis and failed power supply.
2. Ensure the power supply on/off switch is in the "O" off position.
3. Disconnect the power cord tie strap from the power cord and unplug the power cord from the power supply.
4. Using your thumb and forefinger, unscrew both ejection are captive screws until loose and swing the ejection arms out until they are fully open.
5. Pull the power supply out of the chassis, being careful not to damage the circuit board connector extending from the back of the power supply.
6. With the ejection arms fully open, slide the new power supply into the chassis slot until it contacts the chassis backplane and the ejection arms begin to swing closed.
7. Push the ejection arms closed fully and secure both captive screws to seat and secure the power supply in the chassis.
8. Ensure the power supply on/off switch is in the "O" off position.
9. Plug the power cord into the new power supply and attach the power cord tie strap to the power cord.
10. Place the power supply on/off switch to the "I" on position. The Power status LED should be a steady green and the Power status LED and Fan LED should be off.
11. Go to the Maintenance > Hardware screen of the BUI. Click for the controller and then click PSU to verify that the icon is green for the newly installed power supply.

Replacing a SIM Board

The SIM boards are hot-swappable so you can replace them without removing power to the system. The SIM boards are multi-pathed, so you can remove one of the SIM boards at any time, regardless of the state of the blue SIM OK indicator. A faulted SIM board is indicated by an amber LED.

1. Locate the failed SIM at the back of the disk tray.
2. Label and disconnect the tray interface cables.
3. Use two hands to disconnect the SAS cable. Grasp the metal body of the connector with one hand and firmly grasp and pull the tab gently toward the connector body with the other, then pull the connector body outward to extract it from the bulkhead. Do not twist or pull the tab in any direction other than parallel with the connector body or it may break. If the tab breaks, use a small sharp object (such as a fine-tipped screwdriver) to lift the metal spring at the top of the connector shell to unlatch it.
4. Loosen the two extraction arm captive screws using your thumb and forefinger. If the captive screws are too tight to loosen by hand, use a No.2 Phillips screwdriver to loosen each screw.
5. Pull each ejector tab outward and push to the sides to release and partially eject the SIM from the chassis.
6. Grasp the middle of the SIM board and slide it out of the slot.
7. With the ejector arms in the full open position, align the new SIM board with the open slot and slide it into the tray until the ejector arms contact the tray connectors and begin to swing closed.
8. Swing both ejector arms in until they are flush with the SIM board panel to seat the board.
9. Tighten both captive screws to secure the board.
10. Reconnect the SAS interface cables to their original locations.
11. Wait approximately 60 seconds for the SIM board to complete its boot process, at which time the Power LED should be solid green and the SIM locate LED should be off.
