1 Use the arrow keys or press Tab to move to the Boot Volume Size field.
2 Press Enter to display a text box.
3 Enter the size in Gigabytes that should be assigned to the boot volume.
4 Press Enter again to accept the size.
To confirm unit configuration
1 Press Tab to select the OK button and press Enter to confirm creation of
the unit.
Or, if you want to cancel the creation of the unit, tab to Cancel and press
Enter.
2 If you leave the Unit Write Cache field enabled and do not have a BBU
installed, 3BM will ask you to confirm that you want to enable write
cache.
The unit is not actually created and no data is overwritten until you have
finished making all your changes and press F8.
3 If the volume summary screen appears, review the information and press
any key to continue.
Multiple volumes will be created if you entered a Boot Volume Size of
greater than zero (0), or if auto-carving is enabled and the combined size
of the drives in your unit is large enough to divide it into multiple
volumes. For more information about auto-carving, see “Using Auto-
Carving for Multi LUN Support” on page 92.
Note: Setting a Boot Volume Size is optional. In addition, if you specify a boot
volume, you do not have to install your operating system onto it. For more
information about creating a boot volume, see “Boot volume size” on page 103. If
the size of your array is 2TB or greater, you may also want to review the information
about carving the unit into multiple volumes. For details, see “Using Auto-Carving
for Multi LUN Support” on page 92.
