C0030002 — "Error in RDD" — disk array fault on the CT console

Canon Medical (Toshiba) CT error code, reported by the RTM RDD (raw data disk array).

What C0030002 means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 and Aquilion S16 and Asteion Super4 and Aquilion 16 CT systems, status code C0030002 indicates: "Error in RDD" — disk array fault on the CT console. The code originates in the RTM RDD — raw data disk array section of the RTM RDD (raw data disk array). Severity level A1 (Alarm — high severity).

Reported action: Inspect the raw data disk array for a failed disk or fan before continuing — the status LEDs on the front of each slot, and those beside the fibre-channel connectors at the rear, report power, fan and drive state. Record the acquisition that triggered the alarm; disk replacement and the RDD reconfiguration that follows it are service tasks, and drive slot order must be preserved or the stored data becomes invalid..

Reported on Aquilion 16, Aquilion RX/V4-62R004, Aquilion ONE/V4.2, Aquilion S16, Asteion Super4 and V3.20R003. It comes from the 102:Device RTM RDD group of the console error table, where the OEM text reads "Error in RDD.", graded A1 (high-severity alarm). RDD is the Raw Data Disk Array that holds the scan raw data used for reconstruction; on the Aquilion 16 console it is the fibre-channel disk array mounted in the REC BOX.
