Preparing To Remove And Replace Parts; Replacing A Node Canister; Canister Memory Module - IBM Storwize V7000 Unified Problem Determination Manual

Each replaceable unit has its own removal procedure. Sometimes you can find that
a step within a procedure might refer you to a different remove and replace
procedure. You might want to complete the new procedure before you continue
with the first procedure that you started.
Remove or replace parts only when you are directed to do so.

Preparing to remove and replace parts

Before you remove and replace parts, you must be aware of all safety issues.
Before you begin
First, read the safety precautions in the IBM Systems Safety Notices. These
guidelines help you safely work with the Storwize V7000 Unified.

Replacing a node canister

Remove and replace a node canister.
Replacing a Storwize V7000 Gen2 node canister
To replace a faulty node canister with a new one received from CRU or FRU stock,
use this procedure. When replacing a node canister, aim to maximize drive and
system availability by maintaining one online node in the control enclosure with
the faulty node canister. If you cannot maintain at least one node canister online in
the system, then you might need to follow the system recovery procedure after
replacing the faulty node canister.
Procedure
1. Follow "Procedure: Removing a Storwize V7000 Gen2 node canister" on page
279 to remove the faulty node canister.
2. Remove the lid of the faulty canister, as described in "Procedure: Removing
and replacing the lid of a Storwize V7000 Gen2 node canister" on page 285.
Do the same to the replacement canister.
3. Some components inside the faulty node canister must be transferred to the
replacement canister. Transfer each of the following components as necessary:
v The battery, as described in "Replacing the battery in a Storwize V7000
Gen2 node canister" on page 315.
v The host interface adapters in one control enclosure, as described in
"Replacing a Storwize V7000 Gen2 host interface adapter" on page 371.
v Memory modules, as described in "Replacing a Storwize V7000 Gen2 node
canister memory module (16 GB DIMM)" on page 370.
v The compression pass-through adapter or compression accelerator, as
described in the installation description of upgrading the hardware to
install the compression accelerator.
4. Replace the lid of the faulty canister and the lid of the replacement canister, as
described in "Procedure: Removing and replacing the lid of a Storwize V7000
Gen2 node canister" on page 285.
5. Open the release lever of the replacement canister.
6. Push the replacement canister into the slot of the enclosure that the faulty
canister was removed from, until it stops.
7. Finish inserting the replacement canister by closing its release lever so that the
