Adding a DIMM

Adding a DIMM

A storage node supports up to 14 DDR4 DIMMs.

Impact on the System

Before adding a DIMM, you must power off the P36E or C36E node. This will adversely affect the services running on the node. Exercise caution when performing this operation.

Prerequisites

  • The adding DIMM is ready.

Precaution

  • Only professional technical support engineers are allowed to add a DIMM.
  • A P36E or C36E node has two power modules. Ensure that both are disconnected.
  • The DIMM has only one installation direction. If a DIMM cannot be properly seated in a slot, do not exert excess force on the module to avoid damaging the DIMM or slot.
  • The adding memory modules must be the same as the other memory modules. If new memory modules are different from the old memory modules, it is recommended to change all old memory modules in the node.
  • It is recommended to add same capacity memory modules in same type of nodes. If memory capacity in same type of nodes is different, it could cause faulty due to unbalanced performance between nodes.
  • Before adding a DIMM, record the system memory capacity for check and comparison after the replacement.

Do not install DIMM in 001(E) to ensure that data on the NVDIMM can be normally accessed.

The following lists rules to install a DIMM:

  • For a C36E node, configure one CPU in position CPU1. For a P36E node, configure two CPUs.
  • A dual-processor storage node has 14 DDR4 DIMM slots, as shown in Figure 3-114 and Table 3-5. NVDIMM is located at 000(A) in Figure 3-114.
    Figure 3-114  Memory riser (dual-processor)

  • Table 3-5 lists the memory channels.

    2. Tighten the latch to secure the ejector lever of the enclosure cover using flat-head screwdriver, as shown in step 3 in Figure 3-122.
  16. Put the storage node into the cabinet.
    1. Arrange at least four persons to lift the storage node on both sides, align the inner rails on the storage node with the holding rails, and push the storage node into the cabinet along the holding rails, as shown in Figure 3-123.

      Figure 3-128  Starting to clear NVDIMM data

    5. Wait 20 seconds. Check whether the displayed dialog box states "Clear NvDimm flash success. Please reboot system!"

      • If yes, go to 19.f.
      • If no, contact technical support.

  20. During the system startup, the basic input/output system (BIOS) interface is displayed. Check the system memory capacity.
    1. If information similar to the following is displayed, press Delete repeatedly. The BIOS interface is displayed, as shown in Figure 3-131.

      Figure 3-131  BIOS startup page

      NOTE:

      If a dialog box that informs you of entering the password is displayed, enter the BIOS password (default: Huawei12#$).

    2. On the BIOS interface that is displayed, check the system memory capacity, as shown in Figure 3-132.

      Figure 3-132  Checking memory capacity

      NOTE:
      • If the system memory capacity equals the actual memory capacity, the installation is successful. Then restart the device.
      • If the system memory capacity is less than the actual memory capacity, the installation fails. Remove and reinsert the DIMM.

  21. Repeat 8 to 20 on nodes that to be adding memory modules.
  22. Restart nodes added memory modules and power on the other nodes in the system.
  23. Wait for about 10 minutes then log in to DeviceManager, click Alarms, check if there are any major alarms or more critical ones.

    • If yes, rectify the fault according to suggestion.
    • If no, no further operations are required.

  24. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 Routine Maintenance.

    • If all inspection items are successful: The inspection is successful.
    • If some inspection items fail the inspection: The inspection is failed. Rectify the faults by taking recommended actions in the inspection reports. You need to reperform inspection after rectifying. If the inspection is still failed, contact Huawei technical support.

Follow-up Procedure

After adding the DIMM, label the replaced DIMM to facilitate subsequent operations.
