SCSI_LOG 9F "Jan 16, 2006"
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
illumos DDI specific (illumos DDI).
PARAMETERS
dip
Pointer to the dev_info structure.
String naming the device.
Error level.
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 buffer.
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(8). 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.
