Configuring Early Tape Creation
Early Tape Creation is a way to generate a physical copy of virtual data prior to an export (realize) operation
being requested. Using the ETC feature enables export operations to complete faster.
1 From the menu bar, select Setup→ Early Tape Creation.
The Early Tape Creation screen lists the parameters that must be defined when configuring Early Tape
Creation.
• Enter Maximum Concurrent Processes - The maximum number of physical drives to use for
Early Tape Creation operations. This parameter must be set to a value larger than zero (0). The
number of available drives appears in brackets and is 1 less than the number of physical drives on
the Pathlight VX, thereby making at least 1 drive available for other system activity.
• Enter Media Percentage Full - Specifies how full virtual media needs to be before it is a candidate
for Early Tape Creation. The default value is 90%. The minimum setting is 75%. Media will not be
a candidate for Early Tape Creation if it is less than 75% full.
• Early Tape Creation Window: Enter Start Time - Creates a window when Early Tape Creation
will be active.
• Early Tape Creation Window: Enter End Time - Creates a window when Early Tape Creation will
be active.
All Day is the default setting to allow Early Tape Creation to happen at any time. It is recommended
that this process run in the background while no other processes, such as backups, are running.
2 Enter valid values for the parameters and click Apply.
The Progress Window appears, which contains information on the status of the Early Tape Creation
configuration.
• If Success appears in the Progress Window: Early Tape Creation was successfully configured.
• If Failure appears in the Progress Window: Early Tape Creation was NOT configured. To view the
troubleshooting procedures, click View Recommended Actions. To view the error details, click
Error Log for information on why Early Tape Creation was not configured. To configure Early Tape
Creation, repeat Step 1
and Step 2.
3 Click Close to close the Progress Window.
Note
Early Tape Creation only applies to virtual media with a physical counterpart
in an attached tape library. If the virtual media does not have a physical
counterpart, Early Tape Creation does not generate a physical copy.
Note
Early Tape Creation functionality is deactivated if the Maximum Number
of Physical Drives parameter is set to zero (0).
Note
Once the Progress Window appears, you cannot cancel or stop this
action. However, you can close the window by clicking the X in the upper-
right of the screen, but confirmation of success or failure is NOT shown.
