Replacing a BaseIO Card in an SGI

™

300H Server

A video of this procedure is available.

After troubleshooting and verifying the symptoms of a BaseIO card failure, complete the following

procedure to prepare the system for BaseIO replacement, remove the faulty BaseIO card, install the

new card, and return the system to operational status.

BaseIO Card Failure Symptoms

The following symptoms may indicate BaseIO card failures:

• eth0 is not available.

• eth0 performance is degraded.

• USB ports are not available.

• Boot drives are not accessible.

• System does not boot.

Safety Precautions

A fully-loaded chassis weighs approximately 125 pounds. Do not attempt to remove a chassis from

the rack by yourself.

You do not need to completely remove the chassis from the rack to replace a BaseIO card. Slide the

chassis out the front of the rack until the safety locks engage at the halfway point to keep the chassis

in place. Then, remove the front top cover to access parts for replacement.

Be sure to observe all ESD, electrical, and safety precautions when you perform the BaseIO card

replacement procedure. For more information, refer to the SGI UV 300 System User Guide, SGI

publication number 007-6351-00x.

Estimated Time Required

15 to 30 minutes.

Tools Required

A T10 TORX screwdriver.

System Preparation

Complete the following steps to prepare the system for the BaseIO card replacement procedure:

1. Have the customer shut down the SAP HANA database.

2. Have the customer shut down the operating system.

3. Run

uv3dmp

to log the hardware status prior to replacing the part:

rmc> uv3dmp

4. Power down the system.

5. Disconnect the chassis from site power.

6. Provide clearance for the chassis to slide in the rack:

a. Remove the bezel.

b. Remove the NUMAlink and other cables from the front of the chassis.

c. Remove the power cables from the rear of the chassis.

BaseIO Card Replacement Procedure

Removing a BaseIO Card

1. Grasp the handles and slide the chassis out the front of the rack until the chassis locks in place.

2. Remove the T10 TORX screws that secure the front top cover to the chassis.

3. Slide the cover toward the front of the chassis and lift off of the chassis.

Caution: Components inside the chassis can be hot. Wait at least five minutes before removing

components from the chassis.

4. Disconnect the cables from the BaseIO card.

5. Remove the Base IO retaining screw from the top of the bulkhead.

6. Remove the SSD drives from the BaseIO card and note the location of each drive.

7. Grasp the BaseIO card and pull straight up to remove it from the chassis.

Installing a BaseIO Card

1. Reinstall the SSD drives into the correct location on the BaseIO card.

2. Install the replacement BaseIO card by aligning it with the appropriate slot and pushing down

until it is fully seated.

3. Secure the BaseIO card with the retaining screw.

4. Reconnect the cables to the BaseIO card.

5. Replace the front top cover and secure with the T10 TORX screws.

6. Slide the chassis into the rack.

You will have to release the latches at the halfway point. Push the lock tab on the left side of

the chassis down, and push the lock tab on the right up to release.

7. Reconnect the NUMAlink and other cables on the front of the chassis.

8. Replace the bezel.

9. Reconnect the power cables on the rear of the chassis.

After BaseIO Card Replacement

Complete the following steps to return the system to operational:

1. Connect power to the system.

2. Run the

nl7cfg

utility from the RMC to verify cabling.

rmc> nl7cfg

Recable and run the utility again if necessary.

3. Have the customer boot the operating system.

4. Modify the

/etc/udev/rules.d/70-persistent-net.rules

file:

a. Change the eth0 entry to match the new MAC address listed in the eth1 entry.

b. Remove the eth1 entry that was created.

c. Reboot the system.

5. Run

uv3dmp

to log the hardware status after replacing the part:

rmc> uv3dmp

6. Run

sgi_health_check

to verify the performance and configuration for the system:

• For an SAP HANA appliance, use:

sgi_health_check -f

• For an SAP HANA TDI system, use:

sgi_health_check -t

7. Have the customer restart the SAP HANA database.
