Replacing a Lenovo Storage 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.
