PARAMETERS

22       dip                     Pointer to the device info node  for  this  HBA
23                               driver.
24
25
26       devp                    Pointer  to  a scsi_device(9S) structure of the
27                               target.
28
29
30       default_scsi_options    Value returned if no match is found.

DESCRIPTION

34       The scsi_get_device_type_scsi_options() function looks up the  property
35       device-type-scsi-options-list,  which  can  be  specified  in the HBA's
36       driver.conf(4) file. This property allows specification of scsi-options
37       on a per-device-type basis.
38
39
40       The formal syntax is:
41
42         device-type-scsi-options-list = <duplet> [, <duplet> *];
43
44
45
46
47       where:
48
49         <duplet> := <vid+pid>, <scsi-options-property-name>
50
51
52
53
54       and:
55
56         <scsi-options-property-name> = <value>;
57
58
59
60
61       The  string  <vid+pid> is returned by the device on a SCSI inquiry com‐
62       mand. This string can contain any character  in  the  range  0x20-0x7e.
63       Characters  such as double quote (") or single quote ('), which are not
64       permitted in property value strings, are  represented  by  their  octal
65       equivalent  (for  example, \042 and \047). Trailing spaces can be trun‐
66       cated.
67
68
69       For example:
70
71         device-type-scsi-options-list=
72                 "SEAGATE ST32550W",  "seagate-options",
73                 "EXABYTE EXB-2501".  "exabyte-options",
74                 "IBM OEM DFHSS4S",  "ibm-options";
75
76         seagate-options = 0x78;
77         exabyte-options = 0x58;
78         ibm-options = 0x378;
79
80
81
82
83       The scsi_get_device_type_scsi_options() function searches the  list  of
84       duplets   for   a  matching  INQUIRY  string.  If  a  match  is  found,
85       scsi_get_device_type_scsi_options() returns the corresponding value.
86

RETURN VALUES

88       scsi_get_device_type_scsi_options()  returns  the  scsi-options   value
89       found,  or  if  no match is found the default_scsi_options value passed
90       in.
91

CONTEXT

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