IV. CONSIDERACIONES FINALES

Controller nodes contain two types of DIMMs, control cache and data cache.

NOTE: If the failed node is already halted, it is not necessary to shutdown the node because it is not part of the cluster.

To replace a cache DIMM:

1. Connect the maintenance PC to the SP using the serial connection and start an spmaint session.

2. In the 3PAR Service Processor Menu, select option 7 Interactive CLI for an InServ, then select the desired system.

3. Issue the shownode -i command to identify the DIMM manufacturer and manufacturer part number.

4. Issue the servicenode start <nodeID> command to service the node. The node LEDs will appear blue.

5. Type exit to end the CLI session and to return to the 3PAR Service Processor Menu.

6. Before disconnecting the cables from the front of the controller node, note the locations ot the cables, or note or label them. The drive-side Fibre Channel cables are marked to simplify this task.

7. Select option 4 InServ Product Maintenance.

8. Select option 6 Halt an InServ cluster/node, then select the desired system.

9. Select the desired node and confirm all prompts to halt the node.

10. Allow 2-3 minutes for the node to halt, then verify that the node status LED is flashing green and the node service LED is blue indicating that the node has been halted.

11. Set the node power switch to the OFF position to turn off power on the node.

12. Wearing a wrist-grounding strap, remove the node:

a. Pull the insertion/removal levers out to release the node.

b. Pull the controller node insertion/removal lever out to disengage the node from the chassis midplane.

c. Slide the node part way out of the chassis and hold the node by the bottom and top to remove and carry, and place it on an ESD-safe work surface.

13. Loosen the captive screw then slide and lift the controller node cover to remove.

14. Identify the cache DIMM that requires replacement.

15. To remove, press outward on the two tabs on the sides of the DIMM.

16. Remove the replacement DIMM from its protective packaging.

17. Avoid touching the surface of the DIMM when inserting it into the vacant slot in the controller node.

Figure 32 Replacing a DIMM

18. Insert the DIMM by pushing downward on the edge of the DIMM until the tabs on both sides snap into place.

19. Replace the node cover:

a. Align the controller node cover with the pegs in their grooves, then slide the cover until it is properly seated.

b. Tighten the captive screw on the node cover.

Figure 34 Tightening the Captive Screw

20. Install the node:

a. Align the bottom of the node with the grooves in its slot and slide the node into the node chassis.

b. Push the insertion levers in quickly until the node is seated securely.

21. Set the node power switch to the ON position to turn on power on the node.

NOTE: Once power is applied to the node, it begins to boot. This process can take approximately 5-10 minutes. When complete, the node becomes part of the cluster.

22. While the node is booting, connect the Fibre Channel cables and Ethernet cables to the node, if applicable.

23. Verify that the node LED is blinking green indicating that the node has joined the cluster.

24. In the SP window, select option 7 Interactive CLI for an InServ, then select the desired system.

25. Issue the shownode command to verify the node has joined the cluster.

26. Issue the shownode -i command to verify the memory is operational.
