Alarm — high severityRDD (Raw Data Disk Array)

4003000B — RDD (raw data disk array) fault reported by the RTM

Canon Medical (Toshiba) CT error code, reported by the RDD (Raw Data Disk Array) — RAID status, reported via RTM.

What 4003000B means

On Aquilion RX / V4-62R004 and V3.20R003 and Aquilion ONE / V4.2 CT systems, status code 4003000B indicates: RDD (raw data disk array) fault reported by the RTM. The code originates in the RDD (Raw Data Disk Array) section of the RDD (Raw Data Disk Array) — RAID status, reported via RTM. Severity level A1 (Alarm — high severity).

Reported action: Work the RDD as a whole: check the per-slot disk LEDs on the front panel and the power/FAN LEDs, check the fibre-channel connection to the MHR boards at the rear, and run the console's RDD hardware test. Read the event log for the accompanying RDD condition — the neighbouring codes in this device group separate disk failure, RAID configuration and command-level faults — before replacing any hardware..

Toshiba/Canon Aquilion RX (V4-62R004), V3.20R003 and Aquilion ONE (V4.2) CT systems, on the RDD (Raw Data Disk Array) — the fibre-channel raw-data disk array, run as a RAID set with parity, that stores the raw scan data preprocessed by the MHR boards before reconstruction. These platforms' tables list this code in the RTM (real time manager) RDD device group with the plain message "Error in RDD." and no explanatory sub-text, so read the accompanying event log entry to identify the specific RDD condition.
