Abstract
Data encrypted using a first device-specific key of a first host device is written to a first logical storage device of a storage system. The storage system generates a copy of the first logical storage device, and associates the copy of the first logical storage device with a second logical storage device of the storage system. Data encrypted using a second device-specific key of a second host device is written to the second logical storage device of the storage system. Responsive to a request from the second host device for particular data of the second logical storage device, the storage system determines if the particular data was encrypted using the first key or the second key, and provides the second host device with the particular data and an indication of a result of the determination.
