Recovery of storage device in a redundant array of independent disk (raid) or raid-like array

摘要

A method for managing storage devices in a storage subsystem having an array of storage devices, according to one embodiment, includes determining that a storage device in an array of storage devices has failed. A first candidate storage device having storage device characteristics that match storage device characteristics of the failed storage device is identified. The first candidate storage device is exchanged with a second candidate storage device in response to determining that the second candidate storage device has storage device characteristics that are more similar to the storage device characteristics of the array of storage devices than the first candidate storage device.

1. A method for managing storage devices in a storage subsystem having an array of storage devices, the method comprising:
determining that a storage device in an array of storage devices has failed; identifying a first candidate storage device having storage device characteristics that match storage device characteristics of the failed storage device; exchanging the failed storage device and the first candidate storage device by rebuilding data from the array onto the first candidate storage device; after exchanging the failed storage device with the first candidate storage device, determining that a second candidate storage device would better balance the array of storage devices than the first candidate storage device; and in response to the determination that the second candidate storage device would better balance the array of storage devices than the first candidate storage device, exchanging the first candidate storage device and the second candidate storage device.
