CryptoTarget container configuration

To determine if rebalancing is recommended for an encryption engine, check the encryption engine
properties. Beginning with Fabric OS v6.4, a field is added that indicates whether or not
rebalancing is recommended.
You may be prompted to rebalance during the following operations:
• When adding a new disk or tape target container.
• When removing an existing disk or tape target container.
• After failover to a backup encryption engine in an HA cluster.
• After an failed encryption engine in an HA cluster is recovered, and failback processing has
taken place.
To rebalance an encryption engine, do the following.
1. Log in to the switch as Admin or FabricAdmin.
2. Issue the cryptocfg
--show -localEE command.
3. Look for Rebalance recommended under EE Attributes in the output.
4. If rebalancing is recommended, issue the cryptocfg
--rebalance command. If the encryption
node is a blade, include the blade’s slot number (cryptocfg
--rebalance <slot #>).
Gathering information
Before you begin, have the following information ready:
• The switch WWNs of all nodes in the encryption group. Use the cryptocfg --show
-groupmember -all command to gather this information.
• The port WWNs of the targets whose LUNs are being enabled for data-at-rest encryption.
• The port WWNs of the hosts (initiators) which should gain access to the LUNs hosted on the
targets.
Any given target may have multiple ports through which a given LUN is accessible and the ports are
connected to different fabrics for redundancy purposes. Any given target port through which the
LUNs are accessible must be hosted on only one Brocade Encryption Switch (or pair in case of HA
deployment). Another such target port should be hosted on a different encryption switch either in
the same fabric or in a different fabric based on host MPIO configuration.
A given host port through which the LUNs are accessible is hosted on the same Brocade Encryption
Switch on which the target port (CryptoTarget container) of the LUNs is hosted.
NOTE
It is recommended you complete the encryption group and HA cluster configuration before
configuring the CryptoTarget containers.
