PS Bit
A Parameters Savable (PS) bit of zero indicates that the supported parameters cannot be
saved.
In the field names on this page, the following element type abbreviations
are used:
MT Medium Transport Element (picker/elevator assembly)
ST Storage Element (magazine slots)
I/E Import/Export Element (optionally configured mail slots)
DT Data Transfer Element (tape drive)
In the descriptions that follow, XX and YY are any of the element type
abbreviations.
A StorXX bit value of one indicates that the defined elements provide
independent storage of media. A value of zero indicates that the elements do
not provide independent storage of media. StorDT and StorST are both set
to a value of one. If mail slots are configured, StorI/E is set to one. StorMT is
always set to a value of zero.
An XX à YY bit value of one indicates that the Medium Changer device
supports all MOVE MEDIUM commands where the source is element type
XX, the destination is element type YY, and the element addresses are
otherwise valid. An XX
à YY bit value of zero indicates that the Medium
Changer device does not support MOVE MEDIUM commands where the
source is element type XX, the destination is element type YY, and the
element addresses are otherwise valid.
