Procedure: Identifying which enclosure or canister to service

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

About this task

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.

There are physical differences between control enclosures and expansion enclosures. Depending on the system model, the front of the enclosure might have different features. But, in general, 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.
  • Various LED indicators are visible.
Depending on the system model, the rear of the enclosure might have different features. But, in general, looking at the rear of a rack:
  • Control enclosures contain node canisters that have slots for networking adapters, Ethernet ports, SAS ports, and USB ports. LED indicators are also visible.
  • Expansion enclosures have SAS ports and LED indicators and a service port. The model type is shown on a label.
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.
