Phase

-

Description

-

Before the change

-
  • You can only change the disk type when the disk status is Available or In-use.
  • The disk type cannot be changed when any snapshot of the disk is being deleted.
  • Changing the disk type may affect the disk performance, so change the type during off-peak hours.
-

During the change

-
  • Some operations cannot be performed on the disk. Such operations include creating snapshots, creating backups, expanding the disk capacity, rolling back data from a snapshot, restoring data from a backup, attaching or detaching the disk, deleting the disk, transferring the disk, and creating an image from the ECS.
  • Changing the disk type may take several hours or even longer, and cannot be stopped. The time depends on the throughput, storage space, and original disk type at the time of the change.
  • In rare cases, the change may fail due to resource problems. In this case, you are advised to perform the change again.
  • You can have a maximum of 10 disks with their types being changed at the same time.
  • The OS cannot be changed if you are changing the disk type of a system disk.
-

After the change

-

In rare cases, the disk type may fail to be changed due to a backend issue. If this happens, try again later.
