Warning:
This page is used to format a tape to one or two partitions. Extreme care must be used with this parameter
page to avoid accidental reformatting of a tape. Reformatting will destroy all previous data.
Maximum Additional Partitions
: This field is only valid on MODE SENSE where it is used to report the maximum
number of additional partitions that are supported by the drive. This field is non-changeable, however it accepts all
values as a don’t care. This number is the maximum number of additional partitions supported.
Additional Partitions Defined
: This field specifies the number of additional partitions to be defined for the tape
based on the IDP bit. The maximum allowed is the value returned in the Maximum Additional Partitions field.
FDP
: The Fixed Data Partitions bit is not supported by the drive and if set, a CHECK CONDITION status is returned
with an ILLEGAL REQUEST Sense Key set.
SDP
: The Select Data Partitions bit is not supported by the drive and if set, a CHECK CONDITION status is returned
with an ILLEGAL REQUEST Sense Key set.
IDP
: The Initiator Defined Partitions bit is supported and, when set to one, indicates that the tape shall be partitioned
based on the Additional Partitions Defined field, PSUM and Partition Size field.
The SDX-450V allows the tape to be split into two entirely separate and independent partitions like DDS format.
Each partition will have its own Reference, System and Vendor Group area. The maximum size of a partition will be
the whole tape. The partitions may exist together or the entire tape may be treated as a single partition. This is
illustrated below:
