It's very very strange. I have not found any kind of information about.
Could you post the next?:
lsmod | grep ^dm
uname -a
cat /etc/*release
cat /etc/multipath.conf

Hi,
I have a server program that reads data coming in on USB ports. Device paths are in the format: /dev/ttyUSB0
Now, I would like to log data from another device coming in over Ethernet. My first step is trying to track down what the correct device path is which I am unsure of.

di_devfs_minor_path
di_devfs_path(3DEVINFO) Device Information Library Functions di_devfs_path(3DEVINFO)
NAME
di_devfs_path, di_devfs_minor_path, di_path_devfs_path, di_path_client_devfs_path, di_devfs_path_free - generate and free path names
SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ]
#include <libdevinfo.h>
char *di_devfs_path(di_node_t node);
char *di_devfs_minor_path(di_minor_t minor);
char *di_path_devfs_path(di_path_t path);
char *di_path_client_devfs_path(di_path_t path);
void di_devfs_path_free(char *path_buf);
PARAMETERS
node The handle to a device node in a di_init(3DEVINFO) snapshot.
minor The handle to a device minor node in a snapshot.
path The handle to a device path node in a snapshot.
path_buf A pointer returned by di_devfs_path(), di_devfs_minor_path(), di_path_devfs_path(), or di_path_client_devfs_path().
DESCRIPTION
The di_devfs_path() function generates the physical path of the device node specified by node.
The di_devfs_minor_path() function generates the physical path of the device minor node specified by minor.
The di_path_devfs_path() function generates the pHCI physical path to the device associated with the specified path node. The returned
string is identical to the di_devfs_path() for the device had the device not been supported by multipath.
The di_path_client_devfs_path() function generates the vHCI physical path of the multipath client device node associated with the device
identity of the specified path node. The returned string is identical to the di_devfs_path() of the multipath client device node.
The di_devfs_path_free() function frees memory that was allocated to store the path returned by di_devfs_path(), di_devfs_minor_path(),
di_path_devfs_path(), and di_path_client_devfs_path(). The caller is responsible for freeing this memory by calling di_devfs_path_free().
RETURN VALUES
Upon successful completion, the di_devfs_path(), di_devfs_minor_path(), di_path_devfs_path(), and di_path_client_devfs_path() functions
return a pointer to the string containing the path to a device node, a device minor node, or a device path node, respectively. Otherwise,
they return NULL and errno is set to indicate the error. For a non-NULL return, the path will not have a "/devices" prefix.
ERRORS
The di_devfs_path(), di_devfs_minor_path(), di_path_devfs_path(), and di_path_client_devfs_path() functions will fail if:
EINVAL The node, minor, or path argument is not a valid handle.
The di_devfs_path(), di_devfs_minor_path(), di_path_devfs_path(), and di_path_client_devfs_path() functions can also return any error value
returned by malloc(3C).
