Procedure: Identifying which enclosure or canister to service

Use this procedure to identify which enclosure or canister must be serviced.

To prevent loss of access to data or loss of data when you service your system, it is important to be able to identify the correct enclosure or canister when you complete 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 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 refers to the newer generation of enclosures that are listed in the following tables.

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.

Notes:

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 Monitoring > System 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.
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 Monitoring > System panel.
Select the canister or enclosure to be identified.
Select Action > Identify 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.
