Adding Target Tape Luns For Encryption - Brocade Communications Systems Brocade BladeSystem 4/24 User Manual

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

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.
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.
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.
