Creating a new storage connection requires a
POST request.
It is possible to create a new storage connection without adding a storage domain. The host
id or name is optional; providing it will attempt a connection to the storage via the host.
Example 13.2. Creating a New Storage Connection
13.3.2. Deleting a Storage Connection

Deleting a storage connection requires a
DELETE request. A storage connection can only be deleted if neither storage domain nor LUN disks reference it.
The host
name or id is optional; providing it unmounts the connection from that host.
Example 13.3. Deleting Storage Connection
13.3.3. Updating a Storage Connection
复制链接链接已复制到粘贴板!
Updating an existing storage connection requires a
PUT request. The storage domain must be in either maintenance mode or unattached to successfully update the connection.
Providing the host
name or id is optional; if provided, the host attempts a connection to the updated storage details.
Example 13.4. Updating a Storage Connection
13.3.4. Updating an iSCSI Storage Connection

Updating an existing iSCSI storage connection requires a
PUT request. An iSCSI storage domain must be in maintenance mode or unattached to successfully update the connection.
Example 13.5. Updating a Storage Connection
Adding a new storage domain with existing storage connection requires a
POST request. This is only applicable with file-based storage domains: NFS, POSIX, and local.
Example 13.6. Adding a New Storage Domain with Existing Storage Connection
Attaching an additional storage connection to an iSCSI storage domain requires a
POST request.
Example 13.7. Attaching an Additional Storage Connection to iSCSI Storage
Detaching a storage connection from an iSCSI storage domain requires a
DELETE request.
Example 13.8. Detaching a Storage Connection from iSCSI Storage
DELETE /ovirt-engine/api/storagedomains/iSCSI_Domain_ID/storageconnections/Storage_Connection_ID HTTP/1.1 Accept: application/xml Content-type: application/xml
DELETE /ovirt-engine/api/storagedomains/iSCSI_Domain_ID/storageconnections/Storage_Connection_ID HTTP/1.1
Accept: application/xml
Content-type: application/xml
13.3.8. Defining Credentials to an iSCSI Target
复制链接链接已复制到粘贴板!
When an iSCSI storage domain is added using the Administration Portal, only a single user name and password can be specified for that domain. However, some setups require that each host in the cluster use a separate user name and password. Specific credentials can be applied to each iSCSI target per host by using the
storageconnectionextensions element.
Example 13.9. Defining credentials to an iSCSI target
