scsi_get_device_type_string - look up per-device-type, returning matching information string
#include <sys/scsi/scsi.h> char *scsi_get_device_type_string(char *prop_name, dev_info_t *dip, struct scsi_device *devp);
Solaris DDI specific (Solaris DDI).
Name of string array property that contains a list of paired device-type information.
Pointer to the device info node for this HBA driver.
Pointer to a scsi_device(9S) structure of the target.
The scsi_get_device_type_string() function looks up the prop_name property, which can be specified in the HBA's driver.conf(4)file. This property allows specification of per-device-type information. The syntax for prop_name in a driver.conf(4) file is:
The formal syntax is:
prop_name = <duplet> [, <duplet> *];
<duplet> := "<vid+pid>", "<information"
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, \042 and \047). Trailing spaces can be truncated.
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.
scsi_get_device_type_string() returns a copy of the matching <information> 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);
This function can be called from kernel or interrupt context.
