scsi_log(9F)						   Kernel Functions for Drivers 					      scsi_log(9F)

NAME
       scsi_log - display a SCSI-device-related message

SYNOPSIS
       #include <sys/scsi/scsi.h>
	#include <sys/cmn_err.h>

       void scsi_log(dev_info_t *dip, char *drv_name, uint_t level,
	    const char *fmt, ...);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       dip	   Pointer to the dev_info structure.

       drv_name    String naming the device.

       level	   Error level.

       fmt	   Display format.

DESCRIPTION
       The  scsi_log()	function is a utility function that displays a message via the cmn_err(9F) routine. The error levels that can be passed in
       to this function are CE_PANIC, CE_WARN, CE_NOTE, CE_CONT, and SCSI_DEBUG. The last level is used to assist in displaying debug messages	to
       the  console  only.  drv_name is the short name by which this device is known; example disk driver names are sd and cmdk. If the dev_info_t
       pointer is NULL, then the drv_name will be used with no unit or long name.

       If the first character in format is:

	   o	  An exclamation mark (!), the message goes only to the system buffer.

	   o	  A caret (^), the message goes only to the console.

	   o	  A question mark (?) and level is CE_CONT, the message is always sent to the system buffer, but is written to	the  console  only
		  when	the system has been booted in verbose mode. See kernel(1M). If neither condition is met, the ? character has no effect and
		  is simply ignored.

       All formatting conversions in use by cmn_err() also work with scsi_log().

CONTEXT
       The scsi_log() function may be called from user, interrupt, or kernel context.
