Abstract

An aspect includes a method for receiving a memory allocation request for a logical partition. Partition mirroring is enabled for the logical partition. Unscrubbed memory is allocated to both a first and a second copy of the logical partition, with the second copy of the logical partition mirroring the first copy of the logical partition. Scrubbing of the first and second copy of the logical partitions is initiated. Subsequent to initiating the scrubbing one of the first and second copy of the logical partition is selected and partition mirroring is disabled for the logical partition. The first copy of the logical partition is deallocated based on selecting the second copy of the logical partition. The second copy of the logical partition is deallocated based on selecting the first copy of the logical partition.
