The 4U library Monitor Library: Drive Status page 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: 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. v Density 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. Normally this is set to the drive default (which is to show encr density). Monitor Library: Inventory This page provides detailed information about the tape inventory in the library. A summary of each magazine is shown.
