Adding Target Tape LUNs for encryption

You configure a Crypto LUN by adding the LUN to the CryptoTarget container and enabling the

encryption property on the Crypto LUN. You must add LUNs manually. After you add the LUNs, you

must specify the encryption settings.

When configuring a LUN with multiple paths, the same LUN policies must be configured on all the

LUN’s paths. If there are multiple paths to the same physical LUNs, then the LUNs are added to

multiple target containers (one target per storage device port). See “Configuring encrypted storage

in a multi-path environment” on page 516 for a multi-path configuration scenario.

1. Select Configure > Encryption from the menu bar.

The Encryption Center dialog box displays.

2. Select the encryption group, switch, or encryption engine containing the storage device to be

configured.

3. Click Encryption Targets.

The Encryption Targets dialog box displays.

4. Select a Target storage device from the list, and click LUNs.

The Encryption Target LUNs dialog box displays.

5. Click Add.

The Add Encryption Target Tape LUNs dialog box displays.

This dialog box includes a table of all LUNs in the storage device that are visible to hosts. LUNs

are identified by the Host world wide name, LUN number, and Volume Label Prefix number.

6. Select a host from the Host list.

Before you encrypt a LUN you must select a host and 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.

7. 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 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.
