16
17 resp = client.create_volume_with_snapshot_id(snapshot_id="s-er2Q****", # 快照ID
18 charge_type='Postpaid', # 支付方式
19 cluster_id="DC-jh5q****", # 专属集群ID
20 purchase_count=2) # 购买数量
21 print (resp)查询磁盘列表
使用以下代码查询所有的磁盘列表：
Plain Text
1from baidubce.auth.bce_credentials import BceCredentials
2from baidubce.bce_client_configuration import BceClientConfiguration
3from baidubce.services.bcc import bcc_client

21 print (resp)查询磁盘详情
使用以下代码可以根据磁盘ID查询单个磁盘的详细信息：
Plain Text
1from baidubce.auth.bce_credentials import BceCredentials
2from baidubce.bce_client_configuration import BceClientConfiguration
3from baidubce.services.bcc import bcc_client

14 client = bcc_client.BccClient(config)
15
16 resp = client.get_volume(volume_id='v-3uIJ****') # 指定磁盘ID
17 print (resp)
18 挂载CDS磁盘
使用以下代码将磁盘挂载在指定的BCC实例下，注意CDS磁盘需要挂载在与其处在相同可用区下的BCC实例上。
只有磁盘状态为 Available 且实例状态为 Running 或 Stopped 时才允许挂载：
Plain Text
1from baidubce.auth.bce_credentials import BceCredentials
2from baidubce.bce_client_configuration import BceClientConfiguration
3from baidubce.services.bcc import bcc_client, bcc_model
4
5if __name__ == '__main__':
6 # 设置您的ak、sk和要访问的地域
7 HOST = 'http://bcc.bj.baidubce.com'
8 AK = 'ak'
9 SK = 'sk'
10 # 设置默认配置
11 config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
12 endpoint=HOST)
13 # 创建bcc client
14 client = bcc_client.BccClient(config)
15 # 设置要挂载的磁盘ID
16 volume_id = 'v-***'
17 # 设置要挂载的实例ID
18 instance_id = 'i-***'
19 resp = client.attach_volume(volume_id, instance_id)
20 print(resp)卸载CDS磁盘
使用以下代码将指定的磁盘从实例中卸载。
只有实例状态为 Running 或 Stopped 时，磁盘才可以执行此操作：
Plain Text
1from baidubce.auth.bce_credentials import BceCredentials
2from baidubce.bce_client_configuration import BceClientConfiguration
3from baidubce.services.bcc import bcc_client, bcc_model
4
5if __name__ == '__main__':
6 # 设置您的ak、sk和要访问的地域
7 HOST = 'http://bcc.bj.baidubce.com'
8 AK = 'ak'
9 SK = 'sk'
10 # 设置默认配置
11 config = BceClientConfiguration(credentials=BceCredentials(AK, SK),
12 endpoint=HOST)
13 # 创建bcc client
14 client = bcc_client.BccClient(config)
15
16 # 设置要卸载的磁盘ID
17 volume_id = 'v-***'
18 # 设置所挂载的实例ID
19 instance_id = 'i-***'
20 resp = client.detach_volume(volume_id, instance_id)
21 print(resp)释放CDS磁盘
使用以下代码释放未挂载的CDS磁盘，系统盘不能释放：
- 磁盘释放后不可恢复。默认情况下，该磁盘的所有快照将保留，但会删除与磁盘的关联关系。
-
只有磁盘状态为 Available 或 Expired 或 Error 时才可以执行此操作。
def release_volume(self):
Plain Text1 #设置要释放的磁盘ID 2 volume_id = 'your-choose-volume-id' 3 4 self.assertEqual( 5 6 type(self.client.release_volume(volume_id)), 7 8 baidubce.bce_response.BceResponse)
磁盘扩容
使用以下代码对磁盘进行扩容：
- 磁盘只能进行扩容操作，不支持缩容。
- 只有Available状态的磁盘，才能进行扩容操作。
- 只有磁盘状态为 Available 或 Expired 或 Error 时才可以执行此操作。
- 各磁盘类型可配容量范围详见磁盘性能。

24 new_volume_type="cloud_hp1") # 扩容后磁盘类型, 可取值见：https://cloud.baidu.com/doc/BCC/s/6jwvyo0q2#storagetype
25 print(response)回滚磁盘
使用以下代码用指定磁盘自身的快照回滚磁盘内容：
- 磁盘状态必须为 Available 才可以执行此操作。
- 指定 snapshotId 必须是由 volumeId 创建的快照。
- 若是回滚系统盘，实例状态必须为 Running 或 Stopped 才可以执行此操作。
-
回滚系统盘快照，自本次快照以来的系统盘数据将全部丢失，不可恢复：
from baidubce.auth.bce_credentials import BceCredentials from baidubce.bce_client_configuration import BceClientConfiguration from baidubce.services.bcc import bcc_client, bcc_model
if name == 'main': # 设置您的ak、sk和要访问的地域 HOST = b'http://bcc.bj.baidubce.com' AK = b'ak' SK = b'sk' # 设置默认配置 config = BceClientConfiguration(credentials=BceCredentials(AK, SK), endpoint=HOST) # 创建bcc client client = bcc_client.BccClient(config) volume_id = 'v-vG0z**' # 用于回滚指定磁盘的快照ID，必须为 volumeId 所创建的快照 snapshot_id = 's-HkbJ**' resp = client.rollback_volume(volume_id, snapshot_id) print (resp)

使用以下代码可以实现磁盘续费。
磁盘扩缩容期间不能进行续费操作：

18 billing = bcc_model.Billing('Prepaid', 2)
19 resp = client.purchase_reserved_volume(volume_id=volume_id, billing=billing)
20 print (resp)修改磁盘属性（新）
