Abstract
A method, apparatus, system, and computer-readable storage medium that, in an embodiment, set uncorrectable error indicators in logical memory blocks in response to detecting an uncorrectable error in memory pages associated with the logical memory blocks. If the logical memory block is allocated to a hypervisor, the memory page may be deallocated in response to detection of the uncorrectable error. When an IPL of a partition is subsequently performed, a determination is made whether a logical memory block allocated to the partition previously encountered the uncorrectable error via the uncorrectable error indicator. If the logical memory block did previously encounter the uncorrectable error, the logical memory block is deallocated from the partition. In an embodiment, if spare memory exists, the logical memory block with the previously encountered uncorrectable error is replaced with the spare memory and the IPL of the partition is continued with the spare memory.
