Note: - The version of the FILEE parameter list (TEPEVER) is also updated
(to a 2) to accommodate the longer FILEE parameter list.
- For a given mount, the tape drive obtains (from the Encryption
Key Manager) and stores the key management-related information for
subsequent access. When returning this information to the drive, if
the encoding mechanism for one or both of the EEDKs is a "hash", the
Encryption Key Manager always tries to resolve the "hash" value in
an EEDK to its corresponding key label value and returns only the
hash value if the key label cannot be resolved.
- If the returned key label from the Encryption Key Manager is only
available as a hash value, the control unit automatically converts
the returned hash value to printable EBCDIC and returns this value
as the 64-CHAR key label (padded on the right with blanks X'40').
The returned hash value can be up to 56 bytes in length. This value
is then passed to the file end on volume exit along with the character
string *HASH* appended to the end of the character string in bytes
59-64. For example:
ABDCFAABF15698BCDE222156AB4589BEFCDE9009ACBECCA12345678A *HASH*
