If what we are trying to achieve is to allow multiple key management systems
in the same environment, how about adding a "domain ID"? Then the pair
"domain ID"/key ID should be unique in the environment.

Really, because it is not so clear to me?  Is the T10 Vendor ID that of the
device server that the Set Data Encryption page is sent to?  If so, what is
the value in that?  Or, does the T10 Vendor ID identify the key management
server?  That would make more sense.  It certainly is possible that the key
management is being done in the tape drive (or whatever is interpreting the
Set Data Encryption page).  It is also possible that the key management is
being done outside the device server by an entity that is accessible to the
device server through some out-of-band method.  What if the key management
server does not have a T10 Vendor ID?  For instance, what if it is just a
software application running on one of the servers in a network?  Maybe we
should have the capability of reporting which key management servers are
accessible to the device server and then the Key Reference must use one of
those identifiers with each Key Reference is supplies?
 
All of this came about over a worry that the vendor unique key identifier
was not a good enough way of identifying a key.  I don't think we have
solved this problem yet.

Dwayne, 

Yes, I think it does.  It becomes clear that the Vendor Specific Key is both
the T10 Vendor ID and the Vendor Specific Key Reference and that both will
be used for the OOB method to get the key.

Kevin, 
  
My intention was the T10 Vendor ID + the Vendor Specific Key Reference as a
pair. 
  
Does the following change make this clearer? 
  
Replace 
  
If the KEY FORMAT field is 01h, the KEY field shall contain the T10 VENDOR
INDENTIFICATION field, specified in "T10 Vendor ID Based Designator Format"
section of SPC-4, followed immediately by a Vendor Specific Key Reference
identifying the Key to be used to encrypt or decrypt data. 

with the following. 
  
If the KEY FORMAT field is 01h, the KEY field shall contain the information
shown in the following table.   
  
Table YX - vendor specific key  reference elements: 

Byte
Description 

00 - 07
T10 vendor identification, this element of the KEY field is provided to
associate the key reference to a specific vendor. 

08 - n
vendor specific key reference, this element of the KEY field identifies the
Key to be used by the device server to encrypt or decrypt data

  
See SPC-4 for a description of the T10 vendor identification field element. 
  
If this looks OK to you I will revise my proposal one more time before Paul
incorporates it into 05-446

Dwayne, 

I was concerned about the vagueness of what is used as the reference to be
used in a vendor specific manner.  Is it both the T10 Vendor ID + the Vendor
Specific Key Reference as a pair, or only the Vendor Specific Key Reference.

Kevin I thought that I covered that with the following statement. 
 
If the KEY FORMAT field is 01h, the KEY field shall contain the T10 VENDOR
INDENTIFICATION field, specified in "T10 Vendor ID Based Designator Format"
section of SPC-4, followed immediately by a Vendor Specific Key Reference
identifying the Key to be used to encrypt or decrypt data. 
Were you looking for something more?

Dwayne, 

I thought there was supposed to be some text about how the T10 vendor ID is
used.  More specifically, is the T10 Vendor ID supposed to be part of the
reference value used to get the key or not.
