NAME
       sn - return tape library drive serial numbers

SYNOPSIS
       sn -a b.t.l

DESCRIPTION
       The  sn	program	 will  use several variations of the SCSI READ ELEMENT
       STATUS command to attempt to retrieve  and  display  any	 serialization
       information that the library might have about the drives within it. For
       a description of the formatting of this information, see inquire(8).

SIMPLE OPTIONS
       -a b.t.l
	      Selects a specific ordinal SCSI address, where b is the  logical
	      SCSI  bus,  t is the SCSI target, and l is the SCSI logical unit
	      number (LUN) on that target. See libscsi(8).

       The device selected should be a SCSI medium changer device (i.e. a tape
       library or autochanger)

Sample Output
       If you specify a device that is not a medium changer:

	The device at scsidev@4.3.0 does not seem to be a medium changer

       If  you	select	a  library  that  returns  only serial numbers for the
       drives:

	  <Medium Changer Device HP C7200 G300 at scsidev@0.100.0>
		  <Medium Changer S/N>	  US0EG00002
		  <Medium Changer SCSI-3 Device Identifiers>
			  ATNN:HP      C7200	       US0EG00002
	  <Data Transfer Element 1>
		  <Serial Number>	 CXA21P1213
	  <Data Transfer Element 2>
		  <Serial Number>	 CXA18P2046

     If you select a library that returns only SCSI-3 Device  Identifiers  for
     the drives:

	  <Medium Changer Device HP C7200 G300 at scsidev@0.100.0>
		  <Medium Changer S/N>	  US0EG00002
		  <Medium Changer SCSI-3 Device Identifiers>
			  ATNN:HP      C7200	       US0EG00002
	  <Data Transfer Element 1>
		  <SCSI-3 Device Identifiers>
			  ATNN:QUANTUM DLT8000	       CXA21P1213
	  <Data Transfer Element 2>
		  <SCSI-3 Device Identifiers>
			  ATNN:QUANTUM DLT8000	       CXA18P2046

     If	 you  select  a	 library  that	returns both serial numbers and SCSI-3
     Device Identifiers for the drives:

	  <Medium Changer Device HP C7200 G300 at scsidev@0.100.0>
		  <Medium Changer S/N>	  US0EG00002
		  <Medium Changer SCSI-3 Device Identifiers>
			  ATNN:HP      C7200	       US0EG00002
	  <Data Transfer Element 1>
		  <Serial Number>	 CXA21P1213
		  <SCSI-3 Device Identifiers>
			  ATNN:QUANTUM DLT8000	       CXA21P1213
	  <Data Transfer Element 2>
		  <Serial Number>	 CXA18P2046
		  <SCSI-3 Device Identifiers>
			  ATNN:QUANTUM DLT8000	       CXA18P2046
