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 186 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 174 for instructions.

2. Create a CryptoTarget container of type tape. Refer to the section

“Creating a CryptoTarget

container”

on page 178 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 183

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.
