To prevent loss of access to data or loss of data when
servicing your system, it is important to be able to identify the
correct enclosure or canister when completing a service action. Each
enclosure is identified by its model type and serial number. Model
type and serial number are indicated by labels on the enclosure front
and rear.
Each canister is identified by its enclosure and slot
location. Viewing an enclosure from the rear, slot 1 is on the left
and slot 2 is on the right. There are physical differences between Lenovo Storage V7000 Gen2 control enclosures and expansion enclosures.
Looking at the front of a rack:
- The type of the enclosure, either Control or Expansion, is labeled
on the left bezel.
- The model type and serial number of the enclosure are found at
the bottom of the left bezel.
Lenovo Storage V series Gen2 refers to the newer generation of enclosures
in the following table:

Looking at the rear of a rack:
- Control enclosures contain tall and narrow power supplies at the
far left and right of the enclosure, with the node canisters installed
in between, side by side.
- Expansion enclosures contain short node canisters installed side
by side, above short power supply units also installed side by side.
- Control enclosures contain node canisters that have Ethernet ports,
and USB ports. Expansion enclosures do not have any of these ports.
The model type is shown on a label.
- Each canister is identified by its slot location. Viewing an enclosure
from the rear, slot 1 is on the left and slot 2 is on the right.
A canister is uniquely identified by the enclosure that
it is in and its slot location. This ID is shown as E-C or E|C where
E is the enclosure ID and C is the canister location. On the service
assistant, the ID is known as the Panel.
Note:
- When a node canister is added to a clustered system as a node,
it is given a node name and a node ID. The default node name is nodeN,
where N is the node ID. The node ID does not represent the slot location
of the node. On the page use the dynamic graphic
to show the back of the system. Hover over the canister to display
the node name and canister location. The service assistant home
page also shows both the node name and the canister location. If you
have only the node name, use these panels to determine the node canister
location.
- It is good practice to use this procedure to identify which enclosure
or canister must be serviced, as completing a service action on the
wrong canister can lead to loss of access to data or loss of data.
To control the identify LED of an enclosure or online
canister, use the management GUI:
- Log in to the management GUI for the system.
- Select the panel.
- Select the canister or enclosure to be identified.
- Select to control the identify LEDs for the component.
Alternatively, if a node canister is not online to the system,
use the service assistant to control the identify LED.
- Log in to the service assistant of the node canister to be identified.
- Click Identify at the upper left of
the page to control the identify LEDs.
