Operation Scenarios

Different from system disk images,data disk images contain only service data, and are created using ECS data disks.You can save the service data on the ECS data disks by creating data disk images. This method allows you to import image files of data disks locally and register them as data disk images supported by eSurfing Cloud. You can create an EVS using a data disk image, and then mount the EVS to an ECS for service data migration.

Constraints and Restrictions

Currently, it supports the upload of image files in RAW、qcow2、vmdk、vhd formats. Other types of files must be subject to format conversion.
To create a data disk image in this mode, the resource pool must have Zettabyte Object Storage and you have purchased object storage buckets.
The imported data disk images cannot be used to apply for ECSs like system disk images. They can only be used to apply for data disks.

Operation Steps

Log in to the management Console and select IMSto enter the IMS page.
On the Image list page, click Create Private Image.
Go to the page for creating a private image, and select the data disk image as the image type and the image file as the image source, as shown in the following figure
Enter the image file address, which can be obtained from the file details in the object storage buckets.
Select Linux or Windows as the operating system.
Fill in the data disk size. The size of the data disk cannot be smaller than that of the image file. If the size of the data disk is smaller than that of the image file, the actual data disk size will be the same as the size of the image file.
Fill in the remaining information and click Next and Create Now. The data disk image is created.

Subsequent Operation

After a data disk image is created, you can view it in the private image list.
The operations supported by a data disk image include: View details, apply for a data disk, modify, delete, export, share and unshare.
Use a data disk image to apply for a data disk. Click Apply for Data Diskin the action bar to enter the data disk application interface, as shown in the figure. The operation interface is the same as that for the EVS purchased using a conventional method. Note: When applying for a data disk using a data disk image, you cannot create a data disk using a snapshot.
