Temporary Capacity Prefetch
Since temporary capacity is pooled for the group, adjustments to the temporary capacity balance
can be made even when it is not being consumed. For performance reasons, the Group Manager
anticipates potential future use of temporary capacity and may prefetch an amount of temporary
capacity from one or more member systems. Although temporary capacity will not be used on
a member system unless the “-t” option was specified with the icapmodify command, an
icapmodify command without the -t option may still result in an adjustment of the temporary
capacity balance for members of the group. When this happens, the overall temporary capacity
balance for the group does not change, but there may be differences in the allocation to individual
member systems.
