Master keys
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 5 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, and you will need to discard them and create a new
set.
