Configuring a tape LUN
This example shows how to configure a tape storage device. The basic setup procedure is the same
as for disk devices. Only a subset of configuration options and policy settings are available for tape
LUNs. Refer to
on page 169 for tape LUN configuration options.
1. Create a zone that includes the initiator (host) and the target port. Refer to the section
“Creating an initiator - target zone”
on page 158 for instructions.
2. Create a CryptoTarget container of type tape. Refer to the section
on page 162 for instructions.
a. Create the container, allowing the encryption format to default to Native.
FabricAdmin:switch> cryptocfg --create -container tape my_tape_tgt \
10:00:00:05:1e:41:9a:7e 20:0c:00:06:2b:0f:72:6d 20:00:00:06:2b:0f:72:6d
Operation Succeeded
b. Add an initiator to the CryptoTarget container “my_tape_tgt”.
FabricAdmin:switch> cryptocfg --add -initiator my_tape_tgt \
10:00:00:00:c9:2b:c9:3a 20:00:00:00:c9:2b:c9:3a
Operation Succeeded
c. Commit the transaction.
FabricAdmin:switch> cryptocfg --commit
Operation Succeeded
3. Configure the Crypto tape LUN. Refer to the section
for instructions.
a. Discover the LUN.
FabricAdmin:switch> cryptocfg --discoverLUN my_tape_tgt
Container name:
my_tape_tgt
Number of LUN(s):
1
Host:
10:00:00:00:c9:2b:c9:3a
LUN number:
0x0
LUN serial number:
Key ID state:
Key ID not Applicable
b. Add the LUN to the tape CryptoTarget container. The following example enables the LUN
for encryption. There is a maximum of eight tape LUNs per Initiator in a container.
FabricAdmin:switch> cryptocfg --add -LUN my_tape_tgt 0x0 \
10:00:00:00:c9:2b:c9:3a 20:00:00:00:c9:2b:c9:3a -encrypt
Operation Succeeded
NOTE
When changing the tape LUN policy from encrypt to cleartext or from cleartext to encrypt,
or the encryption format from Brocade native to DF-compatible while data is being written
to or read from a tape backup device, the policy change is not enforced until the current
process completes and the tape is unmounted, rewound, or overwritten. Refer to the
section
“Impact of tape LUN configuration changes”
on page 174 for more information.
c. Commit the configuration.
FabricAdmin:switch> cryptocfg --commit
