Claim:
1. A computer program product for managing an extended power line disruption time for a system having at least one battery backup unit, the computer program product comprising a computer readable storage medium having computer readable program code embodied therein that when executed causes operations to be performed, the operations comprising: maintaining extended power line disruption time information including a first extended power line disruption time currently used in the system and a second extended power line disruption time, wherein the first and second extended power line disruption times comprise a time during which the system continues with read and write operations using power from the at least one battery backup unit before initiating a graceful shutdown procedure of the system, wherein the first and second extended power line disruption times indicated in the extended power line disruption time information are different times and are available for selection to use with the at least one battery backup unit, and wherein a first end-of-life and a second end-of-life correspond to the first extended power line disruption time and the second extended power line disruption time, respectively; receiving a request to change from the first extended power line disruption time to the second extended powerline disruption time; and sending a message to a power distribution unit with information on the second extended power line disruption time to cause the power distribution unit to initiate a graceful shutdown of the system after power is supplied from the at least one battery backup unit for the second extended power line disruption time.
