scsi_get_device_type_scsi_options(9F)
NAME
scsi_get_device_type_scsi_options - look up per-device-type
scsi-options property
SYNOPSIS
#include
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) struc-
ture 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 = [, *];
where:

and:
= ;
The string 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, \042 and \047). 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 con-
text.
