1. A method, comprising:
- operating a first logical partition in a first processing complex of a server cluster in an active mode and a second logical partition in the processing complex in a standby mode;
detecting a failure in a second processing complex of the server cluster; and
in response to said failure detection, activating the standby logical partition in the first processing complex to operate in an active mode.

Abstract
A first logical partition in a first processing complex of a server cluster is operated in an active mode and a second logical partition in the processing complex is operated in a standby mode. Upon detection of a failure in a second processing complex of the server cluster. the standby mode logical partition in the first processing complex is activated to an active mode. In one embodiment, partition resources are transferred from an active mode logical partition to the logical partition activated from standby mode. Other embodiments are described and claimed.
