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 148 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 137 for instructions.
2. Create a CryptoTarget container of type tape. Refer to the section “Creating a CryptoTarget
container” on page 141 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
Rekey policy
Disk LUN: yes
Tape LUN: No
Modify? Yes -enable_rekey time_period
<days>| -disable_rekey Enables or disables the auto rekeying feature on a specified disk
LUN. This policy is not valid for tape LUNs. By Default, the
automatic rekey feature is disabled. Enabling automatic rekeying
is valid only if the LUN policy is set to -encrypt. You must specify a
time period in days when enabling Auto Rekey to indicate the
interval at which automatic rekeying should take place.
Key lifespan
Disk LUN: No
Tape LUN: Yes
Modify? Disks
only. Tape: No
-
key_lifespan time_in_days
| none
Specifies the life span of the encryption key in days. The key will
expire after the specified number of days. Accepted values are
integers from 1 to 2982616. The default value is none, which
means the key does not expire. On tape LUNs, the key life span
cannot be modified after it is set.
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.
