Replacing a Storwize V7000 Gen2 and Storwize V7000 Gen2+ node canister memory
module
You can replace a faulty node canister memory module (16 GB and 32 GB DIMM) with a new
one received from CRU / FRU stock. You can also use this procedure to add more memory
to your node canister.
Before you begin
Note:Storwize® V7000 2076-524 uses different DIMMs
than the Storwize V7000 2076-624and Storwize V7000 2076-U7A models. Be certain to use
the correct DIMM for your model. The memory type for each model is as follows.
Storwize V7000 2076-524 DIMMs are 16 GB, 240 p
socket, DDR3. Valid configurations are 2x16 GB (default configuration) and 4x16 GB (upgrade).
Storwize V7000 2076-624and Storwize V7000 2076-U7A DIMMs are 16 GB and 32 GB,
288 p socket, DDR4. Valid configurations are 2x16 GB (default configuration), 4x16 GB (upgrade) and
4x32 GB (upgrade). Support for 32 GB DIMMS requires code level 7.8.1 or higher.
Important: If you are adding memory to a node canister, you must remove that
node from the system configuration before you start the following procedure. To do so, you can use
the management GUI or the CLI.
To use the management GUI, right-click the node and select Remove.
To use the CLI, enter the following command, where object_id | object_name
identifies the node canister that receives the additional
memory:
rmnodecanister object_id | object_name
If you are replacing a faulty DIMM with a new one from FRU stock, you do not need to remove
the node canister from the system configuration.
Some node canisters, such as a Storwize V7000 2076-624or a Storwize V7000 2076-U7A canister, contain an air
baffle that is mounted on the rear side of the CPU heat sink (Figure 1).
You must remove the air baffle to gain access to the DIMM slots. To do so, grasp the top edge of
the air baffle. Then, lift it straight up from the heat sink screws.
Important: You do not need to remove the heat sink screws to remove the air
baffle.
Figure 1. Locating the air baffle
Locate the DIMM slot with the faulty DIMM.
Slot 1 is next to the battery area. Slot 2 is next to the processor. The slots are marked
1 , 2 , 3 ,
4 as shown in Figure 2
.
Remove the faulty DIMM by applying gentle, outwards pressure
simultaneously to the retaining clips at each end of the DIMM slot
until the DIMM is levered out of the slot.
Touch the replacement DIMM packaging onto a metal area
of the case, then remove the replacement DIMM from its package.
Ensure that the retaining clips of the DIMM slot are open.
Gently place the DIMM in the slot. Ensure that the notches in the DIMM align with the shape of
the slot, as shown in Figure 2.
Apply even, firm, downwards pressure on the DIMM in its
slot until the retaining clips move inwards and engage the edges of
the DIMM.
Ensure that the retaining clips are fully engaged with
the edges of the DIMM.
Gently pull the DIMM upwards and
ensure that it does not become dislodged.
If you removed it from the node canister in step 3, you must reinstall the air baffle. To
do so, slide the two peg holes in the air baffle onto the two rear most screws of the CPU heat
sink.
