Error Codes
When an error occurs during operation of the library, the library stops the current 
operation and displays an error code on the Operator Panel. Unless otherwise noted, 
try to resolve the problem by cycling power to the library and retrying the last 
operation. When following an Action Required procedure to clear an error, test the 
library after each step to determine if the error has been resolved using the Library 
Verify diagnostic (see “Running Library Verify Diagnostics” on page 7-5). If the 
problem persists, continue the Action Required procedure. FRU replacement 
procedures are described in Chapter 9, “Check, Adjust, Remove, and Replace 
Procedures,” on page 9-1.

Encryption
(continued)
An encryption-related error 
is posted…
Check the host application’s error logs, device driver logs, tape 
library error logs, and tape drive error logs for entries that are 
related to encryption. See “Downloading Library Logs” on 
page 7-16, “Downloading Drive Logs” on page 7-16, “Drive 
Error Codes” on page 1-15, and “Tape Drive Sense Data” on 
page 1-28.
A there is a connection 
problem with the 
Encryption Key Manager 
(EKM)…
If you are using library-managed encryption, perform the Key 
Path Diagnostic (see “Running Encryption Key Path 
Diagnostics” on page 7-11) . If the test fails, a problem could exist 
with the IP address, the Ethernet cable, or the EKM server. 
Perform the following:
1. Check the Ethernet connection between the library and the 
EKM server.
2. Check the TCP/IP configuration of the library and the server.
3. Check that the EKM is correctly installed and configured, and 
that the EKM application is properly started (refer to your 
EKM documentation).
4. Ensure that the tape drive is registered in the EKM (refer to 
your EKM documentation).
5. Ensure that a default key label is defined in the EKM (refer to 
your EKM documentation).
6. If you are using application-managed encryption or 
system-managed encryption, check your key proxy server’s 
documentation for a similar test.
