Borrowing from the Common Scratch Pool (CSP) can be turned on or off. Turning
borrowing off provides a means to keep the number of stacked volumes in a pool
constant. Turning borrowing on provides a means for a pool of volumes to
dynamically adjust to a fluctuation in the number of stacked volumes required to
store active data. Borrowing can be further defined as Keep or Return to CSP after
reclaim. If borrowing is turned on and a stacked volume is borrowed, this property
defines whether the stacked volume is returned to the CSP once the stacked
volume is reclaimed or if it is to remain in the borrowing pool.
To modify pool properties, do the following:
1. Select VTS 1 or 2.
2. Select from the list of current stacked volume pools presented in the list box.
Use the mouse or keyboard to highlight the stacked volume pool you want to
modify.
3.
In the Pool Properties for VTS section, modify the fields as needed.
