1. A method, comprising:
operating a first logical partition in a first physical processing complex of a server cluster in an active mode and a second logical partition in the same first physical processing complex in a standby mode, wherein the first physical processing complex includes partition resources transferrable within the first physical processing complex and reallocatable to one of the first and second logical partitions of the first physical processing complex by a hypervisor, which partition resources include at least one of processing and memory partition resources, wherein said standby mode operating has reduced transferrable partition resources allocated by the hypervisor for a logical partition operating in a standby mode as compared to said active mode operating for a logical partition operating in an active mode, wherein said active mode operating includes providing access to a shared resource for a logical partition operating in an active mode and wherein said standby mode operating includes denying access to said shared resource for a logical partition operating in a standby mode;
detecting a failure of a third logical partition in a second physical processing complex of the server cluster different from the first physical processing complex; and
in response to said failure detection, activating the standby logical partition in the first physical processing complex to operate in an active mode.
