scsi_log(9F) Kernel Functions for Drivers scsi_log(9F)NAMEscsi_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:
· An exclamation mark (!), the message goes only to the system buf‐
fer.
· A caret (^), the message goes only to the console.
· 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.
