Hi Eric,

I think there should be a few available. One of them is to look
into /sys per HBA port and per SCSI target, the /proc/scsi/scsi can be
a source for paths.

,eg:
/sys/class/scsi_host/host6/device/rport-6:0-0/target6:0:0/6:0:0:0

This folder has lintape drive number serial_num

Probably there could be easier ways.
