SI(4S) — DEVICES AND NETWORK INTERFACES
NAME
si − SCSI IOASIC Host Adaptor Driver
CONFIG SERIES 5, 5E, 6
controller si0 at kbio ? csr ? priority 2
CONFIG S4000
controller si0 at obio ? csr 0x20 priority 4
All SCSI devices in a Solbourne system use a three layer device driver scheme. The top layer supports a specific type of device (for example disk sd(4s), or tape st(4s)), the middle layer contains common code (scsi(4)), and the lower layer supports specific host adaptor hardware (for example SCSI IOASIC si(4), or SCSI Rimfire sr(4s)). This man page describes the low layer operations for the SCSI IOASIC host adaptor.
The controller line above describes the SCSI IOASIC host adaptor on the Solbourne system board.

DIAGNOSTICS
si%d: failed basic register access! Is SCSI bus held in reset?
This message occurs during boot up if the registers in the WD chip can’t be read/written. This can be caused by the SCSI bus being held in reset by a failed device on the SCSI bus or by cable faults.
si%d: timeout: check scsi termination fuse!
This message occurs during boot up the WD chip is not completing a RESET command. It can be caused by lack of termination.
si%d: %dMHz WD33C9%s %s
This message prints during boot up. It provides information about the type and speed of the WD chip being used, the speed of the SCSI bus, and the version of the driver.
si%d: target %d lun %d: status %x parity error
si%d: target %d lun %d: parity error
si%d: not connected: status %x parity error
si%d: not connected: parity error
A parity error occurred on the SCSI bus. This can be caused by cables which are too long.
si%d: si_reset: asr %b: ltarg.lun %d.%d: lcode(%s)
The scsi bus is about to be reset. This message contains information about the state of the bus during the last bus operation.
si%d: ioasic flush address fail
A cache block failed to flush from the IOASIC.
ioasic: iobus %d: ECC/timeout error
The system board IOASIC detected a multibit ECC error or a Kbus timeout when fetching data for the WD chip.
ioasic: iobus %d: cant clear PO
The Page Overflow condition can’t be cleared from the IOASIC.
