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.
