Term Definitions:

vBOP (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.

vKey Path: This is the avenue where key resolution is performed. This is generally left to be determined by method (and is the same), but can be set differently for some hybrid modes.

vDensity Reporting: This 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 so the drive reports the primary density only.

–Expected Value: Normally this is set to the drive default (which is to show encr density).

–Value of Reporting this Feature: If a legacy setup will not work with a new density code being reported [for whatever software reason] this will allow transparent encryption to still be used.
