Procedure: Identifying which Storwize V7000 Gen1 enclosure or canister to service

Before you begin service actions on an enclosure or canister, verify that you are working on the correct enclosure or canister.

About this task

Procedure

Use the following options to identify an enclosure. An enclosure is identified by its ID and serial number.
  • The ID is shown on the LCD panel on the front left of the enclosure. The serial number is also found on the front left end cap of the enclosure and is repeated on the rear left flange of the enclosure. The enclosure ID is unique within a system. However, if you have more than one system, the same ID can be used within more than one system. The serial number is always unique.
    Note: To change the ID of an enclosure, select Monitoring > System in the management GUI. Use the dynamic image to display the enclosure to rename. Right-click the enclosure and select Modify ID. Use this option to set a unique ID on all your enclosures.
  • Within an enclosure, a canister is identified by its slot location. Slot 1 is the upper canister . Slot 2 is the lower canister. A canister is uniquely identified by the enclosure that it is in and the slot location. The ID can be 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 Name.
    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 an integer number. This number does not represent the slot location of the node. Similarly, the node ID does not indicate the slot location. To display the slot location, select Monitoring > System in the management GUI. Use the dynamic image to display the enclosure that contains the canister that you want to view. The enlarged view represents the actual location of the node. Hover over the node to display the node ID and other details. 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 the service assistant to identify a node canister by turning on the identify LED of the containing enclosure. This option is at the upper left of the service assistant page. It is a good practice to identify a node in this way before you perform any service action. Performing a service action on the wrong canister can lead to loss of access to data or loss of data.
