Abstract
A method for operating a computer data storage system is described. A recoverable error in a data storage device in recognized in response to receiving a command for a write operation. It is determined whether the data storage system is in a degraded state. The write operation encountering the recoverable error is reassigned to a space on a spare data storage device if the data storage system is not in a degraded state. The write operation is stored to reassign to a spare data storage device at a future time if the data storage system is in a degraded state.
