2 Adding target tape LUNs for encryption FIGURE 58 Add Encryption Target Tape LUNs dialog box 5. Select a host from the Host list. Before you encrypt a LUN, you must select a host, then either discover LUNs that are visible to the virtual initiator representing the selected host, or enter a range of LUN numbers to be configured for the selected host. 6. Choose a LUN to be added to an encryption target container using one of the two following methods: • Discover. Click to identify the exposed logical unit number for a specified initiator. If you already know the exposed LUNs for the various initiators accessing the LUN, you can enter the range of LUNs using the alternative method. • Enter a LUN number range. Click Show LUNs to add a range of LUNs to be configured for the selected host. The LUN needed for configuring a Crypto LUN is the LUN that is exposed to a particular initiator. 7. Select the desired encryption mode. Options are: Native Encryption, DF-Compatible Encryption, and Cleartext. • If you change a LUN policy from Native Encryption or DF-Compatible Encryption to Clear Text, you disable encryption. • The LUNs of the target that are not enabled for encryption must still be added to the CryptoTarget container with the Clear Text encryption mode option. NOTE The Re-keying interval can only be changed for disk LUNs. For tape LUNs, expiration of the re-keying interval simply triggers the generation of a new key to be used on future tape volumes. Tapes that are already made are not re-keyed. To re-key a tape, you need to read the tape contents using a host application that decrypts the tape contents using the old key, then rewrite the tape, which re-encrypts the data with the new key. 8. Click OK. The selected tape LUNs are added to the encryption target container. 70 Fabric OS Encryption Administrator's Guide 53-1002159-03
