Updating Applications

The entire cluster can be upgraded from a single node with the command:

cluster upgrade <ISO>|<URL>

Some issues to note:

• By default, the cluster upgrade is carried in parallel on all nodes and without any backup in order to provide a fast upgrade. For backwards compatibility, this command is the same as for example cluster upgrade <ISO> backup none fast.

• Use the cluster upgrade <ISO>|<URL> serial command if the VMware host is under load.

• If a backup is required, use the backup <location> parameter with a location as it was added with the backup add command. The command parameter can for example be:

  cluster upgrade <ISO>|<URL> backup <location>

  A downloadable URL can be specified using cluster|app upgrade <URL> which will first be downloaded before upgrading. For example:

  cluster upgrade http://myserver/path/myfile.iso

  If a downloadable URL is not available, use the instructions detailed under the Download section to copy the application upgrade package to the local server. Once complete, use cluster|app upgrade <ISO path> to upgrade the application, or for example: app upgrade myfile.iso.

A single node can be upgraded using the local variant:

app upgrade <ISO>|<URL>

By default, the upgrade will upgrade the system using the latest ISO upgrade package in the platform user’s directory.

The system will automatically reprovision itself after upgrading if necessary.

Note that the system will automatically perform a full backup before the upgrade so that the system can be rolled back if necessary. The destination for this backup can be specified using the following syntax:

cluster|app upgrade <URL>|<path> backup <backup-destination>

Valid backup destinations can be listed with backup list. If necessary, it is also possible to instruct the system not to perform a backup by specifying the backup destination as None.

See the backup restore section on how to restore a system to a former snapshot in order to revert to the snapshot prior to upgrade.
