scsi_get_device_type_scsi_options(9F)			   Kernel Functions for Drivers 		     scsi_get_device_type_scsi_options(9F)

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 command. 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, 42 and 47). Trailing spaces can be truncated.

       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.
