Procedure: Identifying which enclosure or canister to service

Edit online

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

About this task

To prevent data access loss or data loss when servicing the system, it is important to identify the correct enclosure or canister when you complete a service action.

A canister can also be located 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 slot 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.

To display the node name and canister location in the management GUI, complete the following steps:

  1. Select Monitoring > System Hardware.
  2. On the System Hardware - 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, click Node Canister to highlight the node canister in the graphic and display details for the node canister.

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 data access loss or data loss.

To control the identify LED of an enclosure or online canister, use the management GUI:
  1. Select Monitoring > System Hardware .
  2. On the System Hardware - 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.
