cryptoCfg 2 -key_lifespan time_in_days | none Specifies the lifespan 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. This operand is valid only for tape LUNs. The key lifespan cannot be modified after it is set. -newLUN Indicates that the LUN created does not contain any user data and will be part of a replication configuration. This operand is optional. The presence of this operand is incompatible with the with -keyID, -key_lifespan, and -enable_rekey options. An RSA RKM must be configured and replication must be enabled (cryptocfg --set replication enabled) before invoking this command. Both primary and remote mirror LUNs must be added to their container with the -newLUN option. --modify -LUN Modifies the encryption policies of one or more LUNs in a specified CTC. This command is valid only on the group leader. The following operands are required when modifying a LUN: crypto_target_container_name Specifies the name of the CTC to which the LUNs belong. LUN_Num | range Specifies the LUN number either as a 16-bit (2 bytes) number in hex notation (for example, 0x07) or as a 64-bit (8 bytes) number in WWN format (for example, 0:07:00:00:00:00:00:00). The LUN number must be zero when a tape LUN is specified and the tape drive is a single LUN device. When specifying a range, the LUN numbers must be entered in the 16-bit hex format. initiator_PWWN initiator_NWWN Specifies the initiator by its port WWN and node WWN. You may optionally modify the following LUN policy configuration parameters. Refer to cryptocfg --add -LUN for descriptions of these parameters. [-encryption_format native | DF_compatible] [-encrypt | cleartext] [-enable_encexistingdata | -disable_encexistingdata] [-enablerekey time_period | -disable_rekey] Make sure you understand the ramifications of modifying LUN parameters (such as changing the LUN policy from encrypt to cleartext) for devices that are online and are already being utilized. The following restrictions apply when modifying LUN policy parameters: • When you change LUN policy from encrypt to cleartext the following policy parameters are restored to default (disabled): -enable_encexistingdata, -enable_rekey, and -key_lifespan. • When changing the LUN policy back to encrypt, these parameters need to be reconfigured. Attempting to reconfigure these parameters while the LUN policy is set to cleartext is not permitted and generates an error. • For tape LUNs the -enable_encexistingdata and the -enable_rekey operands are not valid and return an error when executed. • The -key_lifespan parameter cannot be modified for tape LUNs once it has been set.
