Caution –
In FC and SATA configurations with large drive capacities, the size of the
logical drive might exceed the device capacity limitation of your operating system. Be
sure to check the device capacity limitation of your operating system before creating
the logical drive. If the logical drive size exceeds the capacity limitation, you must
partition the logical drive.
