Actions for Cloud Servers¶
You can perform the following actions against an active, running server in the Cloud Control Panel and the API.
Rackspace technical documentation for each cloud service describes all the actions that can be performed with that service’s public API. However, because role-based access control (RBAC) makes it possible to allow some users to perform actions that cannot be performed by other users, your ability to perform the actions listed here depends on the specific permissions granted to the ID you use.
You can learn more about RBAC at Getting Started with Role-Based Access Control (RBAC).
To learn how to perform Cloud Servers actions by using your choice of interface, begin at the following sections:
The rebuild action rebuilds a server on the same physical host with a selected base image or saved snapshot. The image that you select must be within the same operating system family (Windows or Linux). Your public and ServiceNet IP addresses are retained. All data and disk formatting is lost.
The resize action enables a server to sized up or down within the same flavor class. The server is offline during the resize. A new server on a different physical host is reserved, and data is transferred from the source to the destination. After all of the data has been transferred and the public and private IPs have been remapped, the newly sized server is brought online. You have 24 hours to confirm the resize by checking to ensure that your server is working as intended. Confirming destroys the original source server, while reverting moves you back to it. After 24 hours, your resize is automatically confirmed.
This action is not available for all flavor classes. Depending on the presentation of the disks, the option might be limited to up only or disallowed entirely.
Rescue mode builds a new server by using the current server’s image. If the system is unable to access the current server’s image, it uses the base image that server was built from. For example, if you have a server running a CentOS 6.5 snapshot with changes that you have created, the system tries to use that snapshot. If that snapshot is not available, the system uses the base CentOS 6.5 image.
When a server enters rescue mode, a temporary password is issued for logging in to the server. At this point, you can access the file system to recover or troubleshoot any issues. The exact process varies based on the operating system.
You can exit rescue mode at any time, returning your VM to its original state with any changes made. Rescue mode is automatically exited after 24 hours.
The reboot action performs a soft or hard reboot of the server. A soft reboot is a graceful shutdown and restart of the server’s operating system. A hard reboot power cycles your server, which performs an immediate shutdown and restart.
The console action opens a Java web terminal emulator window with a login prompt to the server over a secure HTTPS connection. This action gives you access to the server when access from SSH or RDP might be inhibited because of the server’s configuration or an error state. It might be necessary to install or update Java on the web browser used to access the console or to switch web browsers to ensure proper operation. The console is a backup means to access a server and should not be the primary method of access.
