An apparatus, system, and method enable a new platform storage system to have access to an external storage system having data encrypted thereon by an existing platform storage system. Encryption information corresponding to the encrypted data in the external storage system is stored in a memory in the existing platform storage system. The encryption information stored in the memory of the existing platform storage system is transferred to an encryption table stored in the new platform storage system, so that the new platform storage system can read the encrypted data stored in the external storage system.
A system comprising:
A method of managing a system which includes a first storage system including a first CPU, a first memory, a first storage controller, and one or more first storage devices, a second storage system including a second CPU, a second memory, a second storage controller, and one or more second storage devices, a host computer coupled to both said first and second storage systems, and an external storage system coupled to both said first and second storage systems, wherein said first and second storage systems provide a plurality of volumes from said external storage system to the host computer, the method comprising:
