3.12.2 Delete a virtual server (virtual disk)
Function
This service template disconnects volumes that are connected to instances in a KVM environment that is controlled by OpenStack.
The OpenStack-related terms used in this document are the names displayed in the OpenStack Dashboard. The OpenStack-related terms are:
- Identity
Displayed as "identity" or "KeyStone"
- Project
Displayed as "project" or "tenant"
- Volume
Displayed as "volume" or "block storage"
This service template requires the following servers:
- OpenStack server
A server on which OpenStack is installed
- KVM server
A server on which Kernel-based Virtual Machine is installed
- OpenStack control server
A server that executes the REST API on the OpenStack server
- Instance
An instance that is managed by the OpenStack server or by KVM. A general virtual server.
An overview of the processing is as follows:
(1) This service template disconnects volumes that are connected to instances.
This service template uses instance and volume names that have been specified by the user.
(2) The volumes can be deleted optionally.
This service template uses the volume names that have been specified by the user to delete the volumes.
Points to note concerning property settings:
(1) When volumes are disconnected, this service template waits the number of seconds that has been specified for the openstack.checkVolumeDetachmentInterval property, and then repeats the operation to check the status of the volumes the number of times that has been specified for the openstack.checkVolumeDetachmentCount property. Adjust the value of each property, according to the environment in use.
(2) When volumes are deleted, this service template waits the number of seconds that has been specified for the openstack.checkVolumeDeletionInterval property, and then repeats the operation to check the status of the volumes the number of times that has been specified for the openstack.checkVolumeDeletionCount property. Adjust the volume of each property, according to the environment in use.
Prerequisites
For the most recent information about the prerequisite products for the system, prerequisite products for the system executing the service templates, and the supported OSs for the prerequisite products for the system executing the service templates, see the release notes.
[Required product in the system]
JP1/Automatic Operation 12-00 or later
[Prerequisite products in the system executing the service template]
(1) Prerequisite products for an OpenStack server
- OpenStack
(2) Virtualization environment that manages instances
- Kernel-based Virtual Machine
- VMware vCenter Server
- VMware vSphere ESXi
(3) OpenStack control server
- Microsoft .Net Framework 3.5 or later
[Prerequisite product OS running in the system executing the service template]
(1) Prerequisite OSs for instances
- Red Hat Enterprise Linux Server 6 (32-bit x86), Red Hat Enterprise Linux Server 6 (64-bit x86_64)
- Red Hat Enterprise Linux Server 7 (64-bit x86_64)
(2) Prerequisite OSs for the OpenStack control server
- Windows Server 2008 R2 Standard/Enterprise/Datacenter
- Windows Server 2012 Standard/Datacenter
- Windows Server 2012 R2 Standard/Datacenter
Note that environments where Server Core is installed are excluded.
[Usage conditions of prerequisite products in the system executing the service template]
(1) Conditions related to instances
- Each instance name must be unique in a single project.
(2) Conditions related to volumes
- Each volume name must be unique in a single project.
Cautions
(1) When you disconnect volumes, make sure that they are unmounted. If volumes being mounted are disconnected, the file system might become corrupted.
(2) If specified instances and volumes exist together, the volumes are deleted even if no connection relation exists between the instances and volumes. Therefore, make sure that the specified volume names are correct.
