Common Precautions

Change Host Configuration

1. When choosing "Change Configuration" in the menu, it is required to shut down by default to execute the operation. If you need to upgrade without rebooting, please make sure that the host supports hot upgrading (indicated by "Hot Upgrade" in the Model | Features section) and select the "Hot Upgrade" option from the menu.

2. If you change the size of the system disk, the configuration change may take longer, with a reference time of approximately 30 minutes for every 100 GB. However, there is no need for manual adjustments after the expansion is complete.

3. After expanding the data disk, you need to manually adjust it in the system. For details, see Disk Expansion;

4. Any refunds generated from downgrading the configuration will be immediately credited to your cash account or gift account.

5. The settlement method of the refund/differential generated by changing the configuration is shown in the Explanation Document.

Reinstall Host

1. Reinstalling the host will not change its internal or external IP addresses.

2. Be mindful of the file system changes. For instance, reinstalling CentOS from version 6.x to 7.x may render the data disk unrecognizable.

Delete Host

1. Once a host is deleted, it cannot be recovered. Please proceed with caution and ensure that you back up your data in advance.

2. Deleting a host will automatically unbind any Elastic IP (EIP) and UDisk. If you no longer need these resources, you can delete them on the corresponding management page.

3. If the host is in arrears, deleting the host operation will not delete overdue orders. You still need to pay these orders.

4. If the host has not yet reached its expiration time, deleting the host will trigger a refund, immediately returning to your cash account or gift account. For the refund calculation method, please see the Explanation Document.

Making Images

1. It is recommended to shut down the host before creating an image. Otherwise, there may be a risk of failure to boot after the image is created.

2. Only system disk images are supported. If you wish to back up data disks, please use Data Ark.

Resetting Password

1. Currently, it is necessary to shut down the host in order to reset the password.

2. If the default account has been modified, the password reset may not take effect.
