Modifying Specifications of a Protected Instance

Scenarios

If the specifications of an existing protected instance cannot meet the service requirements, you can perform steps provided in this section to modify the server specifications, including the vCPU and memory.

The following scenarios may involve:

• Modifying the specifications of both the production and DR site servers
• Modifying the specifications of the production site server only
• Modifying the specifications of the DR site server only

Notes and constraints

• The specifications of the protected instance cannot be modified when Server Type of the protection group is set to BMS.
• Certain types of ECSs and those migrated to Huawei Cloud using SMS cannot have their specifications modified on the SDRS console after being used to create protected instances. To change their specifications, delete the protected instances, modify specifications on the ECS console, and then create protected instances again.

Prerequisites

• The protection group is in the Available or Protecting state.
• The protected instance is in the Available, Protecting, or Modifying specifications failed.
• Servers of which the specifications to be modified are stopped.
