Ｉデイスクの停電処理装置。 A power outage detection section that detects an AC input power outage, an interrupt flag generation section that generates an interrupt flag upon detection of a power outage, a microphone processor that instructs the SCSI disk to reset when this interrupt flag is given, and this reset. The SCS consists of a host adapter that receives a command and sends a SCSI reset to the SCSI disk, and a disk controller that is installed on the SCSI disk side and compensates for writing one sector by SCSI reset.
I-disk power outage processing device.
