7h—DATA PROTECTION
Code Meaning Comments
26 10 Data decryption key fail limit
reached
A
SECURITY PROTOCOL OUT command has failed because
an incorrect key has been sent to the drive followed by a
read, and this has happened ten times consecutively.
Action: Further
SECURITY PROTOCOL OUT commands will not
succeed until one of these actions has been taken:
• Unload and reload the current tape.
• Power-cycle the drive.
Advise the user that they are using the wrong key, or that
there is a possible security attack.
27 00 Write-protected This is set if a write operation (
WRITE, WRITE FILEMARKS, or
ERASE) is requested for a write-protected cartridge.
Action: 1. Terminate the current I/O and return the appropriate
error.
2. Send a message to the console indicating that the drive
has been trying to write to a write-protected tape.
3. Subsequent action depends on the application.
2A 13 Data encryption Key Instance
Counter has changed
The drive received a
WRITE command from an initiator that
had locked its encryption parameters to a specific Key
Instance Counter, whose value has now changed.
Action: 1. Issue
SECURITY PROTOCOL IN command to find out what
the current encryption parameters are.
2. Issue a
SECURITY PROTOCOL OUT command to set the
correct security parameters.
3. Notify the user of a possible system configuration issue,
since several initiators are trying to control encryption
parameters.
30 00 Incompatible medium
installed
A write-type operation could not be executed because it is
not supported on the tape type that is loaded.
Action: 1. Terminate the I/O and return the appropriate error.
2. Send a message to the console indicating that writing
is not allowed on the type of tape that is currently
loaded.
3. Prompt the user to insert a different tape type.
4. Log the incident in the system log.
5. The calling application can retry the operation.
30 05 Cannot write medium,
incompatible format
For example, the drive tried to write to a tape of an
incompatible generation.
