Table 5–45 Medium Partition Page Descriptor - Field Descriptions
Field Name Description
PS Parameters Savable. For MODE SELECT, this bit must be 0.
Additional Page Length This field indicates the number bytes in the page. However, the value
does not include bytes 0 and 1. The length is returned in MODE SENSE
commands and must subsequently be set to the same value when
performing MODE SELECT. If the page length does not match that
expected by the drive, a CHECK CONDITION status is returned, sense key
set to ILLEGAL REQUEST.
The drive returns a CHECK CONDITION status with sense key set to
ILLEGAL REQUEST if it receives an unsupported Page Code or a Page
field with values not supported or changeable. In such cases, no
parameters are changed as a result of the command.
Maximum Additional
Partitions Not supported. Must be 0.
Additional Partitions
Defined Must be 0. This field specifies the number of additional partitions to be
defined for the tape based on the settings of the SDP and IDP bits. The
maximum allowed is the value returned in the Maximum Additional
Partitions field. Only one partition is supported, therefore the value of
the field must be 0.

SDP Select Data Partitions. Must be 0.
IDP Initiator Defined Partitions. Must be 0.
PSUM Partition Size Unit of Measure. Must be 0.
