Fixes
New functionality
This code introduces a “power on” event log. The event log will now extract and interpret the reason
for the power on event (i.e. firmware upgrade, assert reset, power on etc.)
Encryption
• When external encryption control is in place and the encryption parameter request policy is set
to "request data encryption parameters when not set", the drive must request a key when a Write
command is received after a read operation. In previous code versions, this was not the case, but
it is now corrected.
• Every time a dataset is read, if the dataset is encrypted and the “First Encrypted Block” indicates
there are no encrypted records on tape, then First Encrypted Block will be changed to reflect the
reality.
• The SSC-3 standard states that if a volume is mounted in the drive, then it is not possible to modify
the external encryption control settings. This has been identified as an issue with certain customers,
