Enter the logical volume’s volser in the Enter the logical volume’s volser ... field,
then select the Find push button. A “Search in progress” message is displayed
while the search is occurring. The appropriate VTS is interrogated for where the
logical volume resides.
If the search is successful and the logical volume does reside on a stacked volume,
data is displayed. The following information can be displayed in the window:
Primary
The primary physical volume that contains the specified logical volume.
Spanned
If the logical volume does not fit entirely on the primary stacked volume,
the remainder of the data is written to this spanned primary stacked
volume. The data that makes up the requested logical volume has been
split between the primary stacked volume and the primary spanned
volume.
Secondary
If a secondary copy of a logical volume has been made (as defined by the
volume’s management class), this is the physical volume that contains the
secondary copy of the logical volume. A logical volume can only have a
secondary copy if Advanced Policy Management is installed and enabled
and the volume’s management class indicates a secondary copy should be
made.
Spanned
If the logical volume does not fit entirely on the secondary stacked volume,
the remainder of the data is written to this spanned secondary stacked
volume. The data that makes up the requested logical volume has been
split between the secondary stacked volume and the secondary spanned
volume.
If the search is not successful, messages are displayed that describe why the search
failed.
