Increasing Instance Storage

You can increase the storage space of a CBH instance without upgrading other specifications.

Constraints

The CBH system data has been backed up.

Before you expand capacity, back up the CBH system data in the event of expansion failures. For details, see Which Types of System Data Can Be Backed Up in the CBH System?

Procedure

  1. Log in to the CBH console.
  2. Locate the row containing the instance you want to expand. In the Operation column, choose More > Expand > Expand Storage.
  3. Select the storage space you want to expand, confirm the billing mode and storage space, and then click Next.
  4. On the details page, confirm the storage of Current Specifications and New Specifications and the price for capacity expansion. Confirm the information and click Pay Now.
  5. Complete the payment.
  6. It takes about 30 minutes for the expansion to complete. During the expansion, no manual actions are required, and the status of the CBH instance will change from Changing to Restarting.
  7. When the CBH instance status changes to Running, the CBH system is available.
