18.104.22.168 Make an Offline Disk Online
Make an offline disk into an online disk.
Context of Use
Admin Tool: A Microsoft Management Console (MMC) component, which is used by the administrator to configure the storage on the server.
Admin Client: The primary actor. The Admin Client is code that is running on the administrator's computer. The Admin Client implements client-side protocol components and consumes the storage services that are offered by the storage server. The Admin Client's interest is to correctly interpret, execute, and display the results of the commands that are issued by administrator.
Administrator: The administrator is the person who administers the storage. The administrator is interested in organizing the storage, setting access rights, and enforcing quota-based limits on the storage. The administrator is external to the Storage Services protocols and interacts with the Storage Services protocols through the Admin Client.
The administrator has configured the Disk Management service on the storage server and has the appropriate access privileges to configure the disks and volumes.
Main success scenario
Trigger: The administrator requests to convert an offline disk to an online disk by using the Admin Tool.
The Admin Tool requests that the Admin Client establish a communication channel to the Disk Management service of the Storage Services protocols.
The Admin Client contacts the Disk Management service to convert an offline disk to an online disk by using the IVolumeClient::ReAttachDisk method, as described in [MS-DMRP] section 22.214.171.124.1.41.
The Disk Management service converts the offline disk to an online disk to store configuration information in an implementation-specific manner.
The required conversion from an offline disk to an online disk and vice versa has completed successfully.
If the communication channel for [MS-DMRP] cannot be established, or it becomes disconnected, the Admin Client attempts to establish a connection multiple times until it fails. The completion of the disk's conversion depends on when the connection failed.
A variation of this use case is to convert an offline disk into an online disk by using the Virtual Disk Service Protocol, as described [MS-VDS]. The main success scenario steps of the variation are identical to those in the main use case as described in this section.
