Why Was a 40-GB EVS Disk Added to the Target Server During the Migration? SMS creates and attaches a 40-GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use basis.
Possible Causes Using SMS requires that you have permissions for SMS, ECS, VPC, IMS and EVS, or the migration will fail. Solution Obtain the required permissions and try again. For details, see Creating a User and Granting Permissions. Parent Topic: Known Errors and Solutions
The EVS quotas are exhausted. To prevent unforeseen spikes in resource usage, there are preset quotas on the EVS disk quantity, the EVS disk capacity, and the EVS snapshot quantity. For details about EVS quotas, see Querying EVS Resource Quotas.
Solution Sign in to the EVS console and locate the disk based on the disk ID displayed in the migration failure cause. Contact customer service to unsubscribe from the disk. After the unsubscription, click Start on the migration task page to continue the migration.

EVS Disks SMS creates and attaches a 40-GB EVS disk to each target server during the migration. These EVS disks are billed on a pay-per-use basis. After the migration is complete, these temporary EVS disks will be released.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Possible Causes The source server did not have Internet access, so it could not communicate with SMS, IAM, ECS, EVS, IMS, VPC, or EPS. To solve this issue, you need to check the source network. Solution Log in to the source server.

In addition, EVS requires that disk capacity be expanded in increments of 1 GB. Therefore, the paired target server disk must be at least 1 GB larger than the source GPT disk.
Elastic Volume Service (EVS) After a migration task is started, SMS attaches a temporary pay-per-use EVS disk to the target server, which will be deleted after the migration is complete. - Cloud Trace Service (CTS) CTS can record SMS operations for querying, auditing, or backtracking
EVS Disks SMS creates and attaches a 40-GB EVS disk to each target server during the migration. These EVS disks are billed on a pay-per-use basis. After the migration is complete, these temporary EVS disks will be released.
If the IAM users who will be added to this group need all SMS permissions, attach system-defined policies SMS FullAccess, OBS OperateAccess, ECS FullAccess, VPC FullAccess, and EVS FullAccess to the group. EVS KMSAccess must be attached if disk encryption is required.

You are advised to replace the local disks with EVS disks. Parent Topic: Disk Management
If the IAM user to be added to this group needs all SMS permissions, attach system-defined policies SMS FullAccess, OBS OperateAccess, ECS FullAccess, VPC FullAccess, and EVS FullAccess to the group. EVS KMSAccess must be attached if disk encryption is required.
