SCSI_GET_DEVICE_TYPE_STRING(9F)SCSI_GET_DEVICE_TYPE_STRING(9F)NAMEscsi_get_device_type_string - look up per-device-type, returning match‐
ing information string
SYNOPSIS
#include <sys/scsi/scsi.h>
char *scsi_get_device_type_string(char *prop_name,
dev_info_t *dip, struct scsi_device *devp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
prop_name
Name of string array property that contains a list of
paired device-type information.
dip
Pointer to the device info node for this HBA driver.
devp
Pointer to a scsi_device(9S) structure of the target.
DESCRIPTION
The scsi_get_device_type_string() function looks up the prop_name prop‐
erty, which can be specified in the HBA's driver.conf(4)file. This
property allows specification of per-device-type information. The syn‐
tax for prop_name in a driver.conf(4) file is:
The formal syntax is:
prop_name = <duplet> [, <duplet> *];
where:
<duplet> := "<vid+pid>", "<information"
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:
scsi_vhci_failover_override =
"STK FLEXLINE 400", "f_asym_lsi",
"SUN T4", "f_tpgs";;
The scsi_get_device_type_string() function searches the list of duplets
for a matching INQUIRY string. If a match is found,
scsi_get_device_type_string returns a copy of the <information> string.
The meaning of the returned <information> string is determined by the
caller.
RETURN VALUESscsi_get_device_type_string() returns a copy of the matching <informa‐
tion> string, or if no match is found, NULL is returned. When a non-
NULL value is returned, the caller is responsible for freeing the
<information> string via:
kmem_free(info, strlen(info) + 1);
CONTEXT
This function can be called from kernel or interrupt context.
