.SH DESCRIPTION
.sp
.LP
The \fBscsi_get_device_type_scsi_options()\fR function looks up the property
\fBdevice-type-scsi-options-list\fR, which can be specified in the HBA's
\fBdriver.conf\fR(4) file. This property allows specification of
\fBscsi-options\fR on a per-device-type basis.
.sp
.LP
The formal syntax is:
.sp
.in +2
.nf
device-type-scsi-options-list = \fI<duplet>\fR [, \fI<duplet>\fR *];
.fi
.in -2
.sp

.sp
.LP
where:
.sp
.in +2
.nf
\fI<duplet>\fR := \fI<vid+pid>\fR, \fI<scsi-options-property-name>\fR
.fi
.in -2
.sp

.sp
.LP
and:
.sp
.in +2
.nf
\fI<scsi-options-property-name>\fR = \fI<value>\fR;
.fi
.in -2
.sp

.sp
.LP
The string \fI<vid+pid>\fR is returned by the device on a SCSI inquiry command.
This string can contain any character in the range 0x20-0x7e. Characters such
as double quote (\fB"\fR) or single quote (\fB\&'\fR), which are not permitted
in property value strings, are represented by their octal equivalent (for
example, \e042 and \e047). Trailing spaces can be truncated.
.sp
.LP
For example:
.sp
.in +2
.nf
device-type-scsi-options-list=
        "SEAGATE ST32550W",  "seagate-options",
        "EXABYTE EXB-2501".  "exabyte-options",
        "IBM OEM DFHSS4S",  "ibm-options";

seagate-options = 0x78;
exabyte-options = 0x58;
ibm-options = 0x378;
.fi
.in -2
.sp

.sp
.LP
The \fBscsi_get_device_type_scsi_options()\fR function searches the list of
duplets for a matching \fBINQUIRY\fR string. If a match is found,
\fBscsi_get_device_type_scsi_options()\fR returns the corresponding value.
.SH RETURN VALUES
.sp
.LP
\fBscsi_get_device_type_scsi_options()\fR returns the \fBscsi-options\fR value
found, or if no match is found the \fBdefault_scsi_options\fR value passed in.
.SH CONTEXT
.sp
.LP
This function can be called from kernel or interrupt context.
