Tape device LUN mapping

Tape device LUN mapping
When performing LUN mapping, ensure that a given LUN number from a backend physical target is
the same across all initiators in the container. Failure to do so can result in unpredictable switch
behavior including blade/switch faults. Use the following command to list the LUNs in the target.
switch:admin> cryptocfg --discoverLUN
NOTE
It is recommended that you follow the above rule if a given LUN on the backend target is LUN
mapped to different initiators.
