Controller Node (Node) Replacement Procedure CAUTION: Customers should replace a controller node only on StoreServ 7200 Storage; other internal components should be serviced by the ASP. CAUTION: Alloy gray-colored latches on components like the node mean that the component is warm-swappable. HP recommends that the node be shutdown (with the power remaining on) before removing this component. Contact your ASP for node diagnosis and shutdown. CAUTION: To prevent overheating, node replacement requires a maximum service time of 30 minutes. NOTE: Be sure to put on your electrostatic discharge wrist strap to avoid damaging any circuitry. Preparation 1. Unpack the replacement node and place it on an ESD safe mat. 2. Remove the node cover: a. Loosen the two thumbscrews that secure the node cover to the node. b. Lift the node cover and remove it. 3. If a PCIe adapter exists in the failed node: a. Unpack the replacement PCIe adapter and place it on the ESD safe mat. b. Remove the PCIe adapter riser card from the replacement node by grasping the blue touch point on the riser card and pulling it up and away from the node. c. Insert the replacement PCIe adapter onto the riser card. d. Replace the PCIe adapter assembly by aligning the recesses on the adapter plate with the pins on the node chassis. This should align the riser card with the slot on the node. Snap the PCIe adapter assembly into the node. 4. Replace the node cover: a. While aligning the node rod with the cutout in the front and the guide pins with the cutouts in the side, lower the node cover into place. b. Tighten the two thumbscrews to secure the node cover to the node. 5. Pull the gray node rod to the extracted position, out of the component. Node Identification and Shutdown Before you begin, use either the HP 3PAR Management Console or HP 3PAR CLI to identify and halt the failed node. NOTE: If the failed node is already halted, it is not necessary to shutdown (halt) the node because it is not part of the cluster. The following figure illustrates the 7200 controller node. 16 Servicing the Storage System

Controller Node (Node) Replacement Procedure
CAUTION:
Customers should replace a controller node only on StoreServ 7200 Storage; other
internal components should be serviced by the ASP.
CAUTION:
Alloy gray-colored latches on components like the node mean that the component is
warm-swappable. HP recommends that the node be shutdown (with the power remaining on)
before removing this component. Contact your ASP for node diagnosis and shutdown.
CAUTION:
To prevent overheating, node replacement requires a maximum service time of 30
minutes.
NOTE:
Be sure to put on your electrostatic discharge wrist strap to avoid damaging any circuitry.
Preparation
1.
Unpack the replacement node and place it on an ESD safe mat.
2.
Remove the node cover:
a.
Loosen the two thumbscrews that secure the node cover to the node.
b.
Lift the node cover and remove it.
3.
If a PCIe adapter exists in the failed node:
a.
Unpack the replacement PCIe adapter and place it on the ESD safe mat.
b.
Remove the PCIe adapter riser card from the replacement node by grasping the blue
touch point on the riser card and pulling it up and away from the node.
c.
Insert the replacement PCIe adapter onto the riser card.
d.
Replace the PCIe adapter assembly by aligning the recesses on the adapter plate with
the pins on the node chassis. This should align the riser card with the slot on the node.
Snap the PCIe adapter assembly into the node.
4.
Replace the node cover:
a.
While aligning the node rod with the cutout in the front and the guide pins with the cutouts
in the side, lower the node cover into place.
b.
Tighten the two thumbscrews to secure the node cover to the node.
5.
Pull the gray node rod to the extracted position, out of the component.
Node Identification and Shutdown
Before you begin, use either the HP 3PAR Management Console or HP 3PAR CLI to identify and
halt the failed node.
NOTE:
If the failed node is already halted, it is not necessary to shutdown (halt) the node because
it is not part of the cluster.
