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.
