Problem Solution
ENCRYPTION
Encryption Error: Displayed
when the drive detects an error
associated with an encryption
operation - if the problem
occurred while the tape drive
was writing data to, or reading
data from, tape
1. Check the host application to ensure the key management application is
providing the correct encryption key.
v Refer to the “Drive Sense Data” on page C-7 returned for an encryption
operation.
v Retry the encryption operation after the key management application
problems have been resolved.
2. Check the operation of the tape drive by resetting the drive (Operator Control
Panel: Service > Service > Drive Power) and running POST.
v Refer to the error code displayed on the Operator Control Panel if the drive
resets and POST fails.
v Retry the encryption operation if the drive reset and POST complete without
errors.
3. Check the media.
v Ensure the correct media is being used. Data encryption is supported with
LTO Ultrium 4, 5, and 6 Data and WORM Cartridges only.
v Retry the encryption operation with the tape cartridge in another encryption
enabled drive. Replace the media if the problem repeats with the same tape
cartridge in multiple drives. If the problem occurred while the tape drive
was running POST or diagnostics, replace the drive. The error code clears
with the first attempted write/read after the encryption key is changed, or
when the drive is placed in maintenance mode.
Encryption-related error is
posted Check the IBM SKLM application's error logs, device driver logs, tape library error
logs, and tape drive error logs for entries that are related to encryption. See
“Service Library: View Logs” on page 5-59, “Service Library: View Drive Logs” on
page 5-60, Chapter 8, “Error codes,” on page 8-1, and “Drive Sense Data” on page
C-7.
Connection problem with the
IBM SKLM application If you are using library-managed encryption, perform the Key Path Diagnostic
(see “Service Library: Key Path Diagnostics” on page 5-62) if this feature is
available. If the test fails, a problem could exist with the IP address, the Ethernet
cable, or the key management server. Perform the following:
1. Check the Ethernet connection between the library and the key management
server.
2. Check the TCP/IP configuration of the library and the server.
3. Check that the key manager is correctly installed and configured, and that the
application is properly started (refer to your key management documentation).
4. Ensure that the tape drive is registered in the key manager (refer to the IBM
SKLM Knowledge Center online).
5. Ensure that a default key label is defined in the key manager (refer to the IBM
SKLM Knowledge Center online).
If you are using application-managed encryption, check your tape backup
application documentation for a similar test.
ERROR CODES
There is an error code in the
error log. Most library or drive errors will result in an error code or error message on the
Operator Control Panel display. An error code history is maintained in the library
or drive error log. See “Service Library: View Drive Logs” on page 5-60 for how to
get the error log over the Operator Control Panel and “Service Library: View
Logs” on page 5-59 to view logs using the Web User Interface.
Look up the error code and try to resolve (see Chapter 8, “Error codes,” on page
8-1 and/or Appendix C, “Sense Data,” on page C-1).
