TABLE 6 LUN parameters and policies
Policy name Command parameters Description
LUN state
Disk LUN: yes
Tape LUN: No
Modify? No -lunstate encrypted |
cleartext Sets the Encryption state for the LUN. Valid values are:
•
cleartext - Default LUN state. Refer to policy configuration
considerations for compatibility with other policy settings.
•
encrypted - Metadata on the LUN containing the key ID of the
DEK that was used for encrypting the LUN is used to retrieve
the DEK from the key vault. DEKs are used for encrypting and
decrypting the LUN.
Key ID
Disk LUN: yes
Tape LUN: No
Modify? No -keyID Key_ID Specifies the key ID. Use this option only if the LUN was encrypted
but does not include the metadata containing the key ID for the
LUN. This is a rare case for LUNs encrypted in Native (Brocade)
mode.
Encryption
format
Disk LUN: yes
Tape LUN: yes
Modify? Yes -encryption_format native Sets the encryption format. Valid values are:
•
Native - The LUN is encrypted or decrypted using the Brocade
encryption format (metadata format and algorithm). This is
the default setting.
Encryption
policy
Disk LUN: yes
Tape LUN: Yes
Modify? Yes -encrypt | -cleartext Enables or disables a LUN for encryption. Valid values are:
•
cleartext - Encryption is disabled. This is the default setting.
When the LUN policy is set to cleartext the following policy
parameters are invalid and generate errors when executed:
-enable_encexistingdata -enable_rekey, and
-key_lifespan.
•
encrypt - The LUN is enabled to perform encryption.
Existing data
encryption
Disk LUN: yes
Tape LUN: No
Modify? Yes -enable_encexistingdata |
-disable_encexistingdata Specifies whether or not existing data on the LUN should be
encrypted. By default, encryption of existing data is disabled.
Encryption policy must be set to -enable_encexistingdata, and
the LUN state must be set to cleartext (default). If the encryption
policy is cleartext, the existing data on the LUN will be overwritten.
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.
