Encryption group and HA cluster maintenance

Performing a manual failback of an encryption engine

By default, failback occurs automatically if an encryption engine that failed was replaced or comes

back online. When manual failback policy is set in the encryption group, you must invoke a manual

failback of the encryption engine after the failing encryption engine was restored or replaced.

Failback includes all of the encryption engine’s target associations. Failback returns all encryption

operations to the original encryption engine after it has been restored, or it transfers operations to

a replacement encryption engine if the original encryption engine was replaced. The failback

operation can only be performed within an HA cluster.

1. Log in to the group leader as Admin or SecurityAdmin.

2. Enter the cryptocfg

--failback -EE command. Specify the node WWN of the encryption engine

to which failover occurred earlier and which is now performing all encryption tasks (current

encryption engine), followed by the node WWN of the encryption engine to which failback

should occur (“new” encryption engine). Specify a slot number if the encryption engine is a

blade.

SecurityAdmin:switch>cryptocfg --failback -EE 10:00:00:05:1e:53:4c:91 \

10:00:00:05:1e:39:53:67

Operation Succeeded

Failover/failback example

The following example illustrates the states associated with the encryption engines during an

active failover and failback process.

• EE2 fails over to EE1.

SecurityAdmin:switch> cryptocfg --show -hacluster -all

Encryption Group Name: brocade

Number of HA Clusters: 1

HA cluster name: HAC3- 2 EE entries

Status: Committed

WWN Slot Number Status

EE1 => 10:00:00:05:1e:53:89:dd 0 Online - Failover active

EE2 => 10:00:00:05:1e:53:fc:8a 0 Offline

• The failed EE2 has come back online, Failover is still active:

SecurityAdmin:switch> cryptocfg --show -hacluster -all

Encryption Group Name: brocade

Number of HA Clusters: 1

HA cluster name: HAC3 - 2 EE entries

Status: Committed

WWN Slot Number Status

EE1 => 10:00:00:05:1e:53:89:dd 0 Online - Failover active

EE2 => 10:00:00:05:1e:53:fc:8a 0 Online

• A manual failback is issued.

SecurityAdmin:switch> cryptocfg --failback -EE 10:00:00:05:1e:53:89:dd 0 \

10:00:00:05:1e:53:fc:8a 0

Operation succeeded.
