12.8. 导入块存储域

过程 12.1. 导入块存储域

1. 在 iSCSI 存储服务器中发现目标：

   POST /ovirt-engine/api/hosts/052a880a-53e0-4fe3-9ed5-01f939d1df66/iscsidiscover
   Accept: application/xml
   Content-Type: application/xml
   
   <action>
       <iscsi>
           <address>192.0.2.0</address>
           <port>3260</port>
       </iscsi>
   </action>

2. 使用上一步中发现的 iSCSI 目标，获取导入候选的存储域列表：

   POST /ovirt-engine/api/hosts/052a880a-53e0-4fe3-9ed5-01f939d1df66/unregisteredstoragedomainsdiscover HTTP/1.1
   Accept: application/xml
   Content-type: application/xml
   
   <action>
       <iscsi>
           <address>192.0.2.0</address>
       </iscsi>
       <iscsi_target>iqn.name1.120.01</iscsi_target>
       <iscsi_target>iqn.name2.120.02</iscsi_target>
       <iscsi_target>iqn.name3.120.03</iscsi_target>
   </action>
   

   Copy to Clipboard Toggle word wrap
   响应显示没有与主机关联的存储域列表，如下所示：

   <action>
       <iscsi>
           <address>192.0.2.0</address>
       </iscsi>
       <storage_domains>
           <storage_domain id="6ab65b16-0f03-4b93-85a7-5bc3b8d52be0">
               <name>scsi4</name>
               <type>data</type>
               <external_status>
                 <state>ok</state>
               </external_status>
               <master>false</master>
               <storage>
                   <type>iscsi</type>
                   <volume_group id="OLkKwa-VmEM-abW7-hPiv-BGrw-sQ2E-vTdAy1"/>
               </storage>
               <available>0</available>
               <used>0</used>
               <committed>0</committed>
               <storage_format>v3</storage_format>
           </storage_domain>
       <status>
           <state>complete</state>
       </status>
       <iscsi_target>iqn.name1.120.01</iscsi_target>
       <iscsi_target>iqn.name2.120.02</iscsi_target>
       <iscsi_target>iqn.name3.120.03</iscsi_target>
   </action>

3. 将 iSCSI 存储域导入到主机：

   POST /ovirt-engine/api/storagedomains/ HTTP/1.1
     Accept: application/xml
     Content-type: application/xml
   
   <storage_domain id="6ab65b16-0f03-4b93-85a7-5bc3b8d52be0">
       <import>true</import>
       <host id="052a880a-53e0-4fe3-9ed5-01f939d1df66" />
       <type>data</type>
       <storage>
           <type>iscsi</type>
       </storage>
   </storage_domain>

过程 12.2. 附加块存储域

1. 将存储域附加到数据中心：

   POST /ovirt-engine/api/datacenters/01a45ff0-915a-45e0-8d56-5253234ac988/storagedomains
   Accept: application/xml
   Content-Type: application/xml
   
   <storage_domain>
       <name>scsi4</name>
   </storage_domain>
   

   Copy to Clipboard Toggle word wrap
2. 在存储域中查找未注册的磁盘：

   GET /ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks;unregistered
   Accept: application/xml
   Content-Type: application/xml

   这将返回有关存储域中任何未注册磁盘的信息，其响应如下：

   <disk href= "/ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks/b662f6da-3e97-4bb6-8a50-bda9980a6e83" id="b662f6da-3e97-4bb6-8a50-bda9980a6e83">

3. 将磁盘附加到存储域：

   POST /ovirt-engine/api/storagedomains/6ab65b16-0f03-4b93-85a7-5bc3b8d52be0/disks;unregistered
   Accept: application/xml
