4.1 Configuring encryption on a single fabric In this section, we show our existing configuration of a host to target LUN via a single fabric only. We will then show the steps that we took to encrypt this target LUN containing existing data. For this single fabric encryption process, we use command-line interface (CLI) commands. 4.1.1 Current configuration In Figure 4-1, we see our current configuration of our host server accessing its cleartext data that resides on a LUN, which is provisioned from the Storwize V7000 over a single SAN fabric. We have two connections to each of the Storwize V7000 node canisters, which provides four paths to the target LUN0.
