Member Replacement in an Array of Information Storage Devices

摘要

An information handling system includes a method for detecting a predictive failure indication for a predictive failure indicated physical disk of a disk group, determining an amount of used storage capacity of a lowest capacity physical disk of the disk group, and comparing a replacement storage capacity of a replacement physical disk to the used storage capacity. When the replacement storage capacity is greater than or equal to the used storage capacity even if the replacement storage capacity is less than a lowest storage capacity of the lowest capacity physical disk of the disk group, replacing the predictive failure indicated physical disk with the replacement physical disk.

1. A method comprising:
detecting a predictive failure indication for a predictive failure indicated physical storage device of a storage device group in an information storage subsystem; determining an amount of used storage capacity of a lowest capacity physical storage device of the storage device group; comparing a replacement storage capacity of a replacement physical storage device to the used storage capacity; when the replacement storage capacity is greater than or equal to the used storage capacity, replacing the predictive failure indicated physical storage device with the replacement physical storage device; and when a higher capacity replacement physical storage device having a higher capacity than the lowest storage capacity becomes available, replacing the replacement physical storage device with the higher capacity replacement physical storage device.
