.SH DESCRIPTION
.sp
.LP
The \fBscsi_log()\fR function is a utility function that displays a message via
the \fBcmn_err\fR(9F) routine. The error levels that can be passed in to this
function are \fBCE_PANIC\fR, \fBCE_WARN\fR, \fBCE_NOTE\fR, \fBCE_CONT\fR, and
\fBSCSI_DEBUG\fR. The last level is used to assist in displaying debug messages
to the console only. \fIdrv_name\fR is the short name by which this device is
known; example disk driver names are \fBsd\fR and \fBcmdk\fR. If the
\fIdev_info_t\fR pointer is \fINULL\fR, then the \fIdrv_name\fR will be used
with no unit or long name.
.sp
.LP
If the first character in \fIformat\fR is:
.RS +4
.TP
.ie t \(bu
.el o
An exclamation mark (\fB!\fR), the message goes only to the system buffer.
.RE
.RS +4
.TP
.ie t \(bu
.el o
A caret (\fB^\fR), the message goes only to the console.
.RE
.RS +4
.TP
.ie t \(bu
.el o
A question mark (\fB?\fR) and \fIlevel\fR is \fBCE_CONT\fR, 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 \fBkernel\fR(1M). If neither
condition is met, the \fB?\fR character has no effect and is simply ignored.
.RE
.sp
.LP
All formatting conversions in use by \fBcmn_err()\fR also work with
\fBscsi_log()\fR.
.SH CONTEXT
.sp
.LP
The \fBscsi_log()\fR function may be called from user, interrupt, or kernel
context.
