A “Fast Ready” category means that the Library Manager can order category
mounts from this category without recalling data from a stacked volume. This
enables quick mount times because the mount request does not require a recall.
To define a “Fast Ready” category, enter the four-digit hexadecimal category
number, select the desired VTS or TS7700 Virtualization Engine (and expire time, if
desired), and select the Add/Modify category push button.
To associate an expire time for the category, define the category. Then, enter a
number in the Expire Time field and select its associated unit. For example, if you
wanted the expire time associated with the category to be six hours, you would
enter

To delete a category from the “Fast Ready” category list, highlight the category in
the list box, then select the Delete category... push button.
Expire Time
The Library Manager and the VTS or TS7700 Virtualization Engine use this
time to expire logical volume data for logical volumes in the defined
“Fast-Ready” category. The minimum expire time is 24 hours. The
maximum expire time is 32,767 hours (approximately 194 weeks). You can
enter the expire time in hours, days, or weeks.
If zero is entered or if no entry is made in this field, the logical volumes
will not be expired.
Hold Selecting the Hold option prevents a logical volume from being selected
for mount processing or to be moved out of its assigned category until the
expire time has elapsed or has been reset to zero.
The Set VTS/VE Category Attributes window has the following push buttons:
