• Multiple Mover Tasks (disk only). If ON, the Mover will allow multiple Mover tasks to access
the disk device.
• Reserve/Release (tape only). An indication of whether a SCSI reservation is taken on the device
when it's opened.
Advice - This is useful on fibre attached tape devices to ensure that HPSS has sole control on the
device. Without the reservation, it is possible for other hosts to interleave SCSI commands to the
drive with those issued by HPSS. This effect could potentially lead to corruption of data.
State. A set of flags describing the current state of the device. The flag states are presented as a list of
flag descriptions for each flag which is currently ON:
• Mounted - A media volume is mounted in the device.
• Open for Read - The device is open for reading.
• Open for Write - The device is open for writing.
• Busy - The device is in use.
• Error Encountered - An error was encountered on the device.
• Hit End-Of-Tape - The end of a tape was detected.
• Client Off Midblock - The device position is in the middle of a block.
• Data to be Synced - There are data that need to be flushed.
Set State. A set of flags showing device state changes which are pending. The flag states are presented as
a list of flag descriptions for each flag which is currently ON. See the State field description above for a
list of potential values.
Volume Flags. Flags which further describe that describe the volume type.
Number of Errors. The number of errors that have occurred on this device since the last time this field
was cleared. Click on the Reset button to the right of the field to reset the count to zero.
Block Size. The size, in bytes, of each data block on this device.
Volume ID. The label (name) of the volume which is currently mounted on this device. If no volume is
currently mounted, this field will be blank.
Bytes Read. The number of bytes that have been read from this device since the last time this field was
cleared. Click on the Reset button to the right of the field to reset the count to zero.
Bytes Written. The number of bytes that have been written to this device since the last time this field
was cleared. Click on the Reset button to the right of the field to reset the count to zero.
Operational Notes
• Setting device attributes through this window will not cause the configuration metadata to be
updated.
• The device statistics fields (number of bytes read, number of bytes written, number of errors) are
all initialized to zero when the mover is initialized.
