Volumes on external storage devices are persistent and independent of the VMs. In contrast, hard disks on the hypervisor datastore are non-persistent and they are destroyed when deleted from the VMs or when the VMs are undeployed. This section covers volumes.

Deleting a Volume

Notes about deleting volumes:

  • You can only delete or remove volumes that are NOT attached to a VM. 
  • You cannot delete persistent template volumes if they are used in a virtual appliance. 
  • When you delete a an Integrated storage volume, it will be deleted in the disk cabinet and the data on the volume will be destroyed. 
  • When you delete a generic iSCSI volume, it will be removed from Abiquo (without deleting it in the disk cabinet).
Warning

If you are working with volumes on VMware hypervisors, do not use the option "delete from disk" because the volume may be destroyed.

To delete a volume, select the volume and click the  Image Removed  button:
