Changing Specifications of a CBH Instance

Prerequisites

  • An EIP has been bound to the CBH instance.
  • You have backed up system data by referring to Backing Up the CBH System Data.
  • You have disabled the CBH system and terminated all other operations in the CBH system.

Procedure

  1. Log in to the CBH console.
  2. Click in the upper left corner on the displayed page and select a region.
  3. Locate the row that contains the target instance, and choose More > Expand > Change Specifications in the Operation column.
  4. Specify New Specifications and click Next.
  5. On the Details page, confirm the order details and click Submit.

    When receiving a network restriction notification, click Enable to eliminate the network restrictions so that specification change can be performed.

    You can view the rules in the security group and firewall ACL and ensure that:
    • Access to port 9443 is allowed in the outbound direction of the security group to which your CBH instance belongs.
    • The subnet where the instance locates is not associated with the firewall ACL, or the ACL rule of the associated firewall allows the instance to access port 9443 in the outbound direction.

  6. If the instance is billed on a yearly/monthly basis, you need to pay for the instance on the payment page.
  7. Return to the CBH instance list page and check the status of the instance.

    The system automatically changes the instance specifications. The entire process takes about 30 minutes.

    The instance status changes from Running to Changing > Restarting > Running. When the instance status changes to Running, the CBH instance can be used.
