DISC
structures logged- ncr_siop, siop_cns, siop_struc
description- The SCRIPTS received a disconnect message for the
current physically threaded command. The state of the
SCSI command was saved. If another command request
was on the ready queue, it was enqueued for SCRIPTS
command execution, otherwise, the SCRIPTS were
placed in an idle loop.
IDOV
structures logged- ncr_siop, siop_cns, siop_struc
description- The SCRIPTS determined that more data bytes were
being transferred across the SCSI bus than what the user
had indicated in the siop_struc. An error is logged in the
siop_struc. The SCRIPTS will be restarted at an entry
point which will either receive bytes into a bit bucket
(DATA-IN) or write an error pattern to the device
(DATA-OUT) until the target transitions out of the
DATA phase.
INIT
structures logged- none
description- This log entry only documents that the SIOP
initialization routine siop_init() was called.
INT
structures logged- ncr_siop, siop_cns, siop_struc
description- An invalid reselection occurred. A device for which no
siop_struc is available, reselected the SIOP.
KICK
structures logged- ncr_siop, siop_cns, siop_struc
description- The Firmware SCSI command startup routine was
entered to process an siop_struc. A command structure
was found and dequeued from the ready queue and then
the command was dispatched to the SCRIPTS for
execution.
