Adding Controllers Using SmartKit

Prerequisites

• C versions of the controller enclosures to be added for expansion and the original storage system are consistent. Otherwise, upgrade the controller software of the earlier version. For specific upgrade methods, refer to Upgrade Guide of the target version.
• The memory size of the controllers to be added for expansion is the same as that of the original storage system.
• Controller enclosures to be added have been powered on.
• The network has been deployed based on the scenario.
• There is no critical or major alarm in the storage system.

• The IP addresses of the management network ports on controller enclosures connected to the management network must be different. For details, see section "Changing IP Addresses of Management Network Ports" in the Installation Guide.

Precautions

• SmartKit is used to expand controllers for the storage system.
• The operation procedure varies with the SmartKit version. The actual GUI prevails.
• For controller enclosure 0, ensure that no Ethernet NICs are installed in slots IOM H9/L9 to IOM H13/L13. If Ethernet NICs have been installed in these slots, remove the Ethernet NICs before controller expansion and insert them back after controller expansion. Otherwise, the Ethernet NICs cannot be used after controller expansion.
