Scenario
Unmount disks from physical servers.
Constraints
l For a Windows-based physical server, ensure that no program is reading data from or writing data into disks before unmounting them online. Otherwise, data may be lost during unmounting.
l For a Linux-based physical server, before unmounting a data disk online, log in to the physical server and run the umount command to disassociate the disk from the file system. At the same time, ensure that no program is reading data from or writing data into the disk. Unmounting fails when reading or writing action is in progress.
Operation Steps
1. Log in to eSurfing Cloud and go to the console.
2. Click 
at the top of the console, and select a region. In this topic, Hong Kong 2 is selected.
3. In the left-side navigation pane, go to Computing > Physical Server Service to go to the physical server list.
4. In the Name/Server Name column, click Instance Name of the target physical server to go to the physical server details page.
5. On the tab below, click Elastic Volume Service. Ensure that no program is accessing the data disk, and then click Unmount to the right of the target disk.
6. Confirm the information in the Unmount EVS pop-up window and click OK.
Note:
l Before unmounting the EVS, ensure that the logical disk of the EVS in the operating system has been unmounted by running the umount command. Otherwise, the EVS may fail to be unmounted.
l If a snapshot is created on the physical server to which the EVS is mounted, the snapshot cannot be used to restore data on the EVS when the EVS is unmounted.
7. After the command is delivered, Successful is displayed. Wait for a while and refresh the page. The data disk is unmounted.
