Dell PowerVault TL4000 - Manual (Page 137)

Term Definitions :
v BOP (Beginning of Partition) : BOP (Beginning of Partition) is a SCSI term,
which in a single partition format is the same as beginning of tape. It means that
policy is determined on writes at LB zero. Appending to a tape [or overwriting
at a non-zero LB] does not change the policy already in use for that tape.
v Key Path : The avenue where key resolution is completed. This avenue is left to
be determined by method (and is the same), but can be set differently for some
hybrid modes.
v Density Reporting : Affects host reporting of density and is included to support
legacy needs for transparency. The default of not masking encrypted densities
means that the host can see a different density code for encrypted vs
non-encrypted tapes (x72 [enc] as opposed to x52 [non-enc]). This feature masks
this code so the drive reports the primary density only. Normally this feature is
set to the drive default (which is to show encr density).
Note: LTO drives do not support setting or reporting various densities, thus
LTO drives always report 0xFE (Other).
