Notes and Constraints Monthly/yearly EVS disks cannot be transferred. Frozen EVS disks cannot be transferred. Encrypted EVS disks cannot be transferred. EVS disks with backups and snapshots available cannot be transferred.
What Is EVS? Overview Elastic Volume Service (EVS) offers scalable block storage for cloud servers. EVS disks provide high reliability, high performance, and come with a variety of disk types.
What Are the Differences Between Expanding Capacity by Expanding an EVS Disk and Creating a New EVS Disk? The differences are as follows: Expanding an EVS disk is when you expand the capacity of an existing EVS disk. Some systems let you expand the capacity of EVS disks in use.
Elastic Volume Service (EVS) Service Specific Terms 1. Definition Service Unavailability means the Elastic Volume Service (EVS) system log shows that EVS was inaccessible for one (1) or more consecutive minutes because of Huawei Cloud. 2.
Managing Encrypted EVS Disks What Is EVS Disk Encryption? EVS enables you to encrypt data on newly created disks as required. For details, see Purchasing an EVS Disk. It uses the industry-standard XTS-AES-256 cryptographic algorithm and keys to encrypt EVS disks.
Extending the Volume Group by Adding an EVS Disk Scenarios If the space of an LVM volume group no longer meets your needs, you can extend the volume group by adding new EVS disks, creating physical volumes, and adding the physical volumes to the volume group.
Deleting a Shared EVS Disk Because a shared EVS disk can be attached to multiple servers, ensure that the shared EVS disk is detached from all the servers before deletion. For details, see Unsubscribing from or Deleting an EVS Disk.
Updating an EVS Disk Function This API is used to update an EVS disk. Calling Method For details, see Calling APIs. URI PUT /v2/{project_id}/volumes/{volume_id} Table 1 Path Parameters Parameter Mandatory Type Description project_id Yes String The project ID.
EVS Overview To achieve persistent storage, CCE allows you to mount the storage volumes created from Elastic Volume Service (EVS) disks to a path of a container. When the container is migrated within an AZ, the mounted EVS volumes are also migrated.
Managing EVS Snapshots EVS Snapshot Overview Using EVS Snapshots
Managing EVS Quotas Querying EVS Resource Quotas Increasing EVS Resource Quotas
Updating an EVS Snapshot Function This API is used to update an EVS snapshot. Calling Method For details, see Calling APIs. URI PUT /v2/{project_id}/snapshots/{snapshot_id} Table 1 Path Parameters Parameter Mandatory Type Description project_id Yes String The project ID.
Example Requests Creating an EVS disk (Use an image to create a non-shared EVS disk in the DSS storage pool. Set the disk type to common I/O, device type to SCSI, and disk size to 40 GiB.)
Creating an EVS Disk Scenarios This section describes how to create an EVS disk by calling APIs. For details about how to call APIs, see Calling APIs. In the following example, APIs are called to create a disk from a snapshot.
EVS Disks What Is Elastic Volume Service? Elastic Volume Service (EVS) offers scalable block storage for ECSs.

Deleting an EVS Snapshot Function This API is used to delete an EVS snapshot. Constraints A snapshot can be deleted only when its status is available or error. Calling Method For details, see Calling APIs.
Updating an EVS Snapshot Function This API is used to update an EVS snapshot. Enterprise project authorization is supported. Calling Method For details, see Calling APIs.
