All group-wide configuration commands are executed on the group leader. Commands that clear group-related states from an individual node are executed on the node. The commands require Admin or SecurityAdmin permissions. Removing a node from an encryption group This procedure permanently removes a node from the encryption group as shown in Figure 71. Upon removal, the HA cluster failover capability and target associations pertaining to the node are no longer present. If you wish to take a node out of a group without disrupting these relationships, use the cryptocfg --replaceEE command. Refer to the section "Replacing an HA cluster member" on page 185 for instructions. The procedure for removing a node depends on the node's status within an encryption group. HA cluster membership and Crypto LUN configurations must be cleared before you can permanently remove a member node from an encryption group. 1. Log into the group leader as Admin or SecurityAdmin. 2. If the node is part of an HA cluster, perform the following steps: a. Remove the node from the HA cluster with the cryptocfg --rem -haclustermember command. b. Clear all CryptoTarget configurations from the member node with the cryptocfg --delete -container command. 3. Determine the state of the node. Log into the member node and enter the cryptocfg --show -groupmember command followed by the node WWN. Provide a slot number if the encryption engine is a blade.
