In addition to the possibility of decryption, there is the issue that you need to get the disks from the array back into the same order they were in the original array with the same type and level of the disk controller. This may be less of a problem with mainframe disk arrays, but it can really be an issue trying to recover anything from an x86 disk array: there are several different arrays with different level of software and unless you get the disks into the same order with the same level of software on the same controller, it is next to impossible to recover anything useful even if the data is un-encrypted or just lightly encrypted (like DES).
