Diagnostic Operations

Because the Receive Diagnostic command is not supported, check the error log
(also referred to as the events log) following a diagnostic failure. This provides
specific details of the error. The error log is available via a log sense command or
from the operator panel.
The uncalibrate diagnostic (page code 90h) uncalibrates all target data. This forces
the library to recalibrate during subsequent operations.
Note – The library generates a Not Ready to Ready Unit Attention Sense Key for
all other initiators after diagnostic operations have completed.
