Abstract
A method that can stably and reliably resume SED from operating system power saving mode is disclosed. The solution comprises a storage lower filter driver and an extra external SCSI I/O queue. The storage lower filter driver is coupled to the storage class driver and configured to provide a SED power saving transaction in response to an operation system power function. An extra external SCSI queue and correspondingly a unique SCSI I/O queue state machine trigger mechanism are included in order to avoid overwhelming the capability of any particular host adapter. A dummy SCSI package is inserted into internal SCSI queue in last phase of operating system power down transaction so that internal SCSI queue can be activated during operation system power resuming.
