Abstract
A computer implemented method for creating an encrypted logical unit is provided. A first identification number is received, the first identification number associated with a first encryption key used to encrypt a first logical unit. The first identification number and the first encryption key are stored at a first secure location, where the first secure location provides the first encryption key to a requester in response to receiving the first identification number from the requester, assuming the requester provides security credentials. A first metadata storage space is defined on the first logical unit, the first metadata storage space comprising a region on the first logical unit that remains unencrypted. The first identification number is stored in the first metadata storage space on the first logical unit.
