Appendix A. Encryption Sense Data
A-5
5 EE 2E Encryption -
Unsupported Type EKM The tape drive received a
corrupted or unrecognized
message from the EKM. The
most likely causes are an
EKM code bug or
incompatible code versions
on the drive and EKM.
Note: This is expected to be a
rare occurrence.
Retry the command if
necessary. If the problem
persists, verify the EKM and
drive code versions are
compatible. As an example, if
the EKM code were updated
to include a new function but
the drive code version does
not recognize the new EKM
function then the code
versions are incompatible. If
the problem still persists,
obtain a drive dump and
EKM (or application if no
EKM is involved) traces, then
refer to your EKM
documentation.
Note: The byte and bit
pointers may be used to
indicate the first bad field in
the message.
5 EE 30 Encryption -
Prohibited Request The requested operation was
not allowed due to the current
mode or state. As an example,
a key path diagnostic was not
allowed because there was a
cartridge in the tape drive. Ensure that the requirements
for the requested operation
have been met. As an
example, before running a
key path diagnostic be sure
the tape drive is empty. If the
problem persists, obtain a
drive dump, then refer to
your EKM documentation.
5 EE 31 Encryption - Key
Unknown A key operation was not
allowed because the key was
not known (not a currently
tracked key).The key that was
used is not a match for this
tape cartridge. Retry the command using the
correct encryption key for the
cartridge.
5 EE 60 Encryption - Proxy
Command Error A command resulted in a key
transition that can’t be
handled by the
application/system proxy.
The proxy reports this
condition - this sense
combination is typically not
produced by the tape drive.
Note: This is only expected in
test environments, not in the
field.
If the problem persists, obtain
a drive dump and traces from
the proxy, then refer to your
EKM documentation.
