Expanding Controllers Using SmartKit

Prerequisites

• The system network has been connected according to the networking diagrams in Connection Between Controller Enclosures.
• Controllers on all controller enclosures have the same memory size.

  You can run the show memory command to query the memory size of a controller.

• All controller enclosures have the same software version.

  You can run the show version all command to query the software version of controller enclosures.

• There is no critical or major alarm in the storage system.
• The public/private key pair of ibc_os_hs is the default values.
• The IP addresses of the management network ports on controller enclosures connected to the management network must be different but on the same network segment. For details, see "Changing IP Addresses of Management Network Ports Using a Serial Port" or "Changing IP Addresses of Management Network Ports Using DeviceManager" in the initialization guide corresponding to your product model.

• The Auto Discovery (AD) process has been enabled on all of the controllers in the new controller enclosure (1). For details on how to enable the AD process, see What Can I Do to Enable the AD Process?

  The AD process is used for message forwarding between controllers during expansion. After enabling the AD process on all of the new controllers, you must add the new controllers using SmartKit within 24 hours. Otherwise, controller expansion will fail and you need to enable the AD process on the new controllers again.

Precautions

• Use SmartKit to expand controllers for the storage system.
• The specific operation may vary according to the SmartKit versions.
