"Finally, there have been a lot of problems reported with Encrypted Communications. Please be sure that your patches are up to date."
BOY, is THAT an understatement.
Also, make sure you understand the difference between ECC and encrypting the tapes - they are NOT the same thing.
Bob, for you, did one of the patches allow starting encryption on a "clean" (for lack of a better word) cell manager via the GUI? When I went through 6.2(1) and enabled ECC, I had to run a command line on the CM and then was able to add ECC for the rest of the clients in the cell.
