| I2O_SCSI_QUEUECOMMAN(9) | Message-based devices | I2O_SCSI_QUEUECOMMAN(9) |
NAME¶
i2o_scsi_queuecommand - queue a SCSI command
SYNOPSIS¶
int i2o_scsi_queuecommand(struct scsi_cmnd * SCpnt, void (*done) (struct scsi_cmnd *));
ARGUMENTS¶
SCpnt
scsi command pointer
done
callback for completion
DESCRIPTION¶
Issue a scsi command asynchronously. Return 0 on success or 1 if we hit an error (normally message queue congestion). The only minor complication here is that I2O deals with the device addressing so we have to map the bus/dev/lun back to an I2O handle as well as faking absent devices ourself.
LOCKS¶
takes the controller lock on error path only
