available. The default value is 1. If the list fills before the Fill Count is exhausted, filling stops and a
message is displayed.
Fill Increment. This field determines how each new volume label is generated. The Fill Increment is
the number by which each automatically generated label will differ from the previous one when a value
is in the Volume Label field and the Fill Count is greater than 1. Valid values are positive integers up to
the number of available drives. The default value is 1. A volume label is six alphanumeric characters.
The Fill Increment is added to the least significant portion of a volume label to generate a new label.
Volume Label. The next label that will be generated and inserted into the table. The labels are generated
when the field loses focus. Select Fill Count, Fill Increment, and Fill Direction before entering a value
in this field.
Fill Direction. Determines which direction filling takes place in the table. By default, Fill Direction is
Horizontal. Select the desired value for this field before entering a Volume Label.
Total Count. The total number of physical volumes in the generated Volume List. This is an
informational field and not directly enterable.
Volume List. A list of volume labels specifying the volumes used to create resources. You cannot enter
labels directly into this list but must instead use the Fill Count, Fill Increment, and Volume Label
fields. Use the scrollbar to navigate the list of labels.
Clear All. This button clears the Volume list and Volume Label field.
Create Resources. Begins the process of creating HPSS storage resources using the displayed data. A
start message is displayed on the status bar, and all window features are disabled, except for the Dismiss
button. This prevents the user from modifying any data on the window while the create request is in
progress.
8.2. Removing Storage Space
Removing storage space from the HPSS system is a two step process:
1. Delete Resources. In the first step, the Core Server virtual volume metadata is deleted; this
process is called deleting storage resources.
2. Export Volumes. In the second step, the physical volumes that belonged to the virtual
volumes are exported from the PVL.
The second step, exporting the volumes from the PVL, is not always necessary. Once the resources are
deleted in step 1, new storage resources can be created on the volumes without the need to export the
volumes from the system and reimport them. Exporting the volumes is necessary only if the volumes are
not going to be reused in the HPSS system, or if for some reason they must be relabeled. The site may
wish to export the volumes if they are to be imported into a different PVR in the system, but this function
can also be accomplished with the Move Cartridges operation.
8.2.1. Deleting Storage Resources
Storage resources can be removed from HPSS volumes by the use of the Delete Resources window or the
remove utility.
Once resources have been deleted, the volumes may be reused or removed from the HPSS system. To
