Attach to VCS instances

After a data disk is created, you need to attach it to a VCS instance and initialize it in the VCS instance before using it.

info

Detach from a VCS instance

To delete a data disk or attach it to another VCS instance, please detach it from the original VCS instance before performing other operations.

For detailed steps of unmounting and detaching data disks, please refer to Detach a data disk.


Delete a data disk

You can delete a disk when it is no longer in use. Once deleted, it will not be billed anymore.

caution
  1. Be careful before deleting the data disk. Once the disk is deleted, it cannot be recovered.
  2. If the state of the data disk is IN-USE, the disk must be detached from the VCS instance and enter the AVAILABLE state first before it can be deleted. If the state of the data disk is RESERVED, it means that this data disk is attached to a VCS instance, and the instance state is Stopped. Please start the VCS instance first before detaching or deleting the data disk.
  3. When a snapshot of the data disk exists, the disk cannot be deleted. Please delete the disk snapshot before deleting the data disk.
  • Enter Data Disk Management page > select the data disk(s) you want to delete > click DELETE at the top.

  • Or click    next to the data disk > click DELETE.
  • Or enter Data Disk Details page> click DELETE at the top.
