Event Code Message Text and Description
4156 KMIP Handshake failure.
4157 KMIP Certificate unknown.
4158 KMIP host name lookup failed.
4159 KMIP certificate verify failed.
4160 Connection to SKLM/GKLM server failed
4161 Internal encryption key handshake failed
4162 for z/OS encryption not licensed
Details and Solution
The TLS connection could not be established
because of Handshake errors during certificate
exchange.
• Check the certificates on server and client
side for valid entries and that they are still
valid and not expired.
• Verify that TLS1.2 is enabled on the server.
• Check the client and server date/time for
current time.
• Ask your IT personnel for new and valid
certificates.
The server certificate is unknown because its
root certificate is missing or not trusted. Run
a new certificate request with your server or
certificate authority and import the resulting
certificate chain.
The host name on the network could not be
found. It does not exist or is misspelled.
• Verify that the entered host name is correct.
• Check your DNS address in the network
settings.
• Contact your IT personnel to verify the
entered data.
The TLS server certificate could not be verified
as a valid and trusted certificate.
• Check if your server root certificate changed.
• Create a certificate request against your
server to generate a new client certificate
based on the changed server certificates.
Retrieving of IPP encryption key failed because
connection to SKLM/GKLM server could not be
established.
Check for availability of server and verify
your server settings. Add a secondary fallback
server if possible.
Retrieving IPP encryption key failed because of
internal data transfer failure between drive and
library.
Verify if the latest drive software is installed. If
the failure reoccurs, check the library event log
for specific events associated with this drive.
Disable SKLM/GKLM for z/OS encryption or
install appropriate license for Library Managed
Encryption.
