Name

i2o_scsi_queuecommand_lck — queue a SCSI command

Synopsis

int i2o_scsi_queuecommand_lck (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
