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 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. To display node canister details in the management GUI, complete these steps:
    1. Select Monitoring > System.
    2. On the System - Overview page, select the directional arrow next to the enclosure that contains the node canister that you want to display.
    3. On the Enclosure Details page, select the node canister in the graphic to display details for the node canister.
  • 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 in the management GUI, complete these steps:
  1. Select Monitoring > System .
  2. On the System - Overview page, select the directional arrow next to the enclosure that contains the node canister that you want to identify.
  3. On the Enclosure Details page, right-click the node canister in the graphic and select Identify from the Actions menu.
Alternatively, if a node canister is not online to the system, use the service assistant to control the identify LED.
  1. Log in to the service assistant of the node canister to be identified.
  2. Click Identify at the upper left of the page to control the identify LEDs.
