Adding target tape LUNs for encryption
20
•
The New LUN option can be used only if replication is enabled for the encryption group.
•
If the local LUN contains host data, configuring it with the New LUN option will cause the data
on the last three blocks of the LUN to be lost. Before using the New LUN option, you must
migrate the contents of the LUN to another LUN that is larger by at least three blocks. The new,
larger LUN can then be used when creating the SRDF pair. The remote LUN of the SRDF pair
must be of the same size. The original smaller LUN with user data can be decommissioned.
Adding target tape LUNs for encryption
You can 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
paths to the LUN. 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).
1. Select Configure > Encryption from the menu task bar to display the Encryption Center
dialog box (Refer to Figure 185 on page 526).
2. Select a group, switch, or engine from the Encryption Center Devices table that contains the
storage device to be configured, then select Group/Switch/Engine > Targets from the menu
task bar.
NOTE
You can also select a group, switch, or engine from the Encryption Center Devices table, then
click the Targets icon.
The Encryption Targets dialog box displays ( Figure 301 ). Initially, the table is empty. You must
add LUNs manually.
