NOTE
Windows operating systems do not require smart card drivers to be installed separately; the driver
is bundled with the operating system. However, you must install a smart card driver for UNIX
operating systems. For instructions, refer to the Installation Guide that comes with your system.
The key is divided among the cards in the card set, up to 10. The quorum of cards required to
restore the master key must be less than the total number of cards in the set, and no greater than
five. For example, when the master key is backed up to a set of three cards, a quorum of any two
cards can be used together to restore the master key. When the master key is backed up to a set of
10 cards, a quorum size of up to five cards can be configured for restoring the master key. Backing
up the master key to multiple recovery cards is the recommended and most secure option.
NOTE
When you write the key to the card set, be sure you write the full set without canceling. If you cancel,
all previously written cards become unusable; you will need to discard them and create a new set.
