Trying to configure the sgen(7D) driver to take attach to the tape library.

However, the Solaris multipathing driver (STMS aka Solaris Traffic Manager Software aka MPxIO) has bound against the tape library so the sgen driver cannot control it.

 Ex :

lrwxrwxrwx   1 root     sys           67 Apr 24 13:09 c1t50014380160535E8d0 -> ../../../devices/scsi_vhci/medium-changer@g50014380160535e8:changer

Here, the presence of the 'scsi_vhci' entry in the path name indicates that the library is under the control of the Solaris multipathing driver.
