Crypto LUN configuration

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 Table 6 on page 174 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 162 for instructions.
2. Create a CryptoTarget container of type tape. Refer to the section “Creating a CryptoTarget
container” on page 167 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 “Configuring a Crypto LUN” on page 172
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
Write Early Ack
Disk LUN: No
Tape LUN: Yes
Modify? Tape
Only. Disk: No
-write_early_ack
disable|enable
Specifies the Tape Write pipelining mode of the LUN. Two Write
Pipelining modes are supported:
disable - Early acknowledgement of commands (internal
buffering) for a tape lun is disabled.
enable - Early acknowledgement of commands (internal
buffering) for a tape lun is enabled.
The default value is enable.
Read Ahead
Disk LUN: No
Tape LUN: Yes
Modify? Tape
Only. Disk: No
-read_ahead
disable | enable
Specifies the Tape Read Ahead mode of the LUN. Two Read Ahead
modes are supported:
disable - The LUN disables the Tape read ahead and Tape
LUN will be operated in unbuffered mode.
enable - The LUN enables the Tape read ahead and Tape LUN
will be operated in buffered mode.
The default value is enable.
