STORAGE CONTROL DEVICE AND CONTROL DEVICE FOR DETECTING ABNORMALITY OF SIGNAL LINE

摘要

A controller module (CM) includes buffers that feed back signals output using respective signal lines used for mutual communication with other CM, and a first detecting unit and a second detecting unit that detect abnormality such that the levels of the signals output using the signal lines do not change from respective specific levels when each level of the fed-back signals does not coincide with an expected level being a level previously determined according to a predetermined timing.

1. A storage control device comprising:
a feedback unit that feeds back a signal output using a signal line used for mutual communication with other storage control device; and a detecting unit that detects abnormality such that a level of the signal output using the signal line does not change from a specific level when a level of the signal fed back by the feedback unit does not coincide with an expected level being a level previously determined according to a predetermined timing.
