NAME
       scsi_get_device_type_scsi_options   -  look  up	per-device-type	 scsi-
       options property

SYNOPSIS
       #include <sys/scsi/scsi.h>

       int    scsi_get_device_type_scsi_options(dev_info_t     *dip,	struct
       scsi_device  *devp, int default_scsi_options);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       dip

	   Pointer to the device info node for this HBA driver.

       devp

	   Pointer to a scsi_device(9S) structure of the target.

       default_scsi_options

	   Value returned if no match is found.

DESCRIPTION
       The  scsi_get_device_type_scsi_options() function looks up the property
       device-type-scsi-options-list, which can	 be  specified	in  the	 HBA's
       driver.conf(4) file. This property allows specification of scsi-options
       on a per-device-type basis.

       The formal syntax is:

       device-type-scsi-options-list = <duplet> [, <duplet> *];

       where:

       <duplet> := <vid+pid>, <scsi-options-property-name>

       and:

       <scsi-options-property-name> = <value>;

       The string <vid+pid> is returned by the device on a SCSI	 inquiry  com‐
       mand.  This  string  can	 contain any character in the range 0x20-0x7e.
       Characters such as double quote (") or single quote ('), which are  not
       permitted  in  property	value  strings, are represented by their octal
       equivalent (for example, \042 and \047). Trailing spaces can  be	 trun‐
       cated.

       For example:

       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;

       The  scsi_get_device_type_scsi_options()	 function searches the list of
       duplets	for  a	matching  INQUIRY  string.  If	a  match   is	found,
       scsi_get_device_type_scsi_options() returns the corresponding value.

RETURN VALUES
       scsi_get_device_type_scsi_options()   returns  the  scsi-options	 value
       found, or if no match is found the  default_scsi_options	 value	passed
       in.

CONTEXT
       This function can be called from kernel or interrupt context.
