Abstract
A storage subsystem has a plurality of storage devices. An indication of failure of at least one of the plurality of storage devices is detected. In response to detecting the indication of failure, monitoring is performed for a further condition. According to the monitored further condition, it is determined whether the at least one storage device has failed or whether communication has been lost to the storage subsystem. In response to determining that communication has been lost, state information of the storage subsystem is preserved to enable restoration of the storage subsystem after communication to the storage subsystem is recovered.
