How to Replace the J4400 Array Chassis Assembly.

Solution

WHAT SKILLS DOES THE ENGINEER NEED

If customer has a CRU-Uplift contract use J4400 Trained engineer

TIME ESTIMATE: 180 minutes

TASK COMPLEXITY: 4

WHAT STATE SHOULD SYSTEM BE IN TO BE READY TO PERFORM RESOLUTION ACTIVITY? :

NOTE: If ASR is enabled, it should be deactivated temporarily before servicing the equipment so that additional unnecessary Service Requests are not created.

DEACTIVATING ASR WITH CAM 6.10: ASR is automatically deactivated when you select "Reserve the tray for maintenance" in Service Advisor, and it is reactivated when you select "Release the tray from maintenance" in Service Advisor.

DEACTIVATING ASR WITH CAM 6.9 OR EARLIER: Before proceeding with the part replacement:

1. Log into CAM.
2. Go to "Storage Systems" -> [your arrayname] -> "Administration" -> "Array Health Monitoring".
3. Uncheck the box "Enable ASR for this array" under the section "Monitoring for This Array". If the box is already unchecked, there is no action required. Remember the status however, as it will matter in step 3 of REACTIVATING ASR WITH CAM 6.9 OR EARLIER below.
4. Click on "Save" if you have unchecked the box in step 3 above.

Verify Chassis Failure:
1. Power LED (front) is amber.
2. Audible alarm sounding.
3. All component fault LEDs green: (Disk(front), SIM Power LED (back), Power supply LEDs (back)).

Prerequisites:
1. Back up all data stored on array.
2. Stop all system I/O to array.
3. ESD Precautions.
4. Remove all power from chassis and components.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing Chassis:
1. From back cabinet, locate chassis being replaced.
2. Disconnect power cord from each power supply.
3. Label mini-SAS cable for reconnection on the replacement chassis.
4. Disconnect mini-SAS cables from each SIM board: Grasp the metal body of the connector, and firmly grasp and pull the tab gently toward the connector body, and then extract the connector from the bulkhead.
5. Power Supply: Loosen two captive thumb screws on power supply ejection levers and swing ejection levers fully outward to partially eject power supply.
6. Pull power supply out of tray. Repeat 5 and 6 to remove each SIM board.
7. Disk Drives: Press release button in and to the right to release the disk extraction lever. Swing extraction lever. Grasp middle of disk drive and pull toward you to remove from tray.
8. Record slot location on outer drive casing for reinstall.
9. Store each disk drive in a static-free environment.
10. Chassis Remove two system locking clips from lower corners of rear chassis.
11. Front of cabinet, loosen four captive screws, two on either side.
12. Grasp each side of chassis and pull it toward you, remove from cabinet.

Installing Chassis:
1. Front of cabinet, slide new chassis into cabinet until front flanges of chassis touch vertical face of cabinet.
2. Tighten captive screws on each side.
3. Back of cabinet, slide system locking clip onto each lower corner of chassis.

Installing CRUs:
1. Front of cabinet, install each disk drive and disk filler. Unlatch and swing extraction lever. Slide each drive into tray until extraction lever engages with tray connectors and the lever begins to swing closed. Press the extraction lever closed.
2. Back of cabinet, install 2 SIM boards in SIM slots. Swing both extraction levers fully open position. Slide it into tray until it engages with tray connectors. Simultaneously push both extraction levers toward middle of board to seat it in tray. Tighten extraction lever captive screws.
3. Repeat Step 2 to install two power supplies.

Finalizing:
1. Back of cabinet, reconnect power cables into power supply.
2. Replace tie strap on each power cord.
3. Turn on power power supplies.

Checking Status:

1. Power-on sequence is  complete and no faults detected if:  All tray and drive OK/Power LEDs are steady green and amber Service Required LEDs are off.
2. If Amber LED is blinking for any module: Reseat module. If still Amber blinking, contact Oracle Customer Service Personnel.
3. If alarm sounds after plugging in first power cord, the alarm will shut off once second power cord is connected.

OBTAIN CUSTOMER ACCEPTANCE
   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

REACTIVATING ASR with CAM 6.10: ASR is automatically deactivated when you select "Reserve the tray for maintenance" in Service Advisor, and it is reactivated when you select "Release the tray from maintenance" in Service Advisor. If ASR was not enabled before beginning this procedure, selecting "Release the tray from maintenance" will not activate it.

REACTIVATING ASR WITH CAM 6.9 OR EARLIER: After proceeding with the part replacement:

1. Log into CAM.
2. Go to "Storage Systems" -> [your arrayname] -> "Administration" -> "Array Health Monitoring".
3. Check the box "Enable ASR for this array" under the section "Monitoring for This Array". Do this ONLY if you unchecked the box in step 3 of DEACTIVATING ASR WITH CAM 6.9 OR EARLIER. If you found the box was unchecked, leave it unchecked now.
4. Click on "Save" if you have checked the box to reactivate ASR.
