Display the elements of the failover group by entering show fogrp <name> - where <name> is one of

the names in the list. For example:

eqcli > show fogrp fo_group1

F/O Group fo_group1:ID = 1

Preferred Peer = eq_001D7D78E13E

Subnet Members (num = 1):

God:Me

Cluster Members (num = 2):

cl01

cl02

No Server Members

Note - At least 2 subnets must be configured, along with their failover IP addresses.

6. When the "sick" Peer has been “healed”, the clusters do not automatically migrate back. For this to occur

you will need to invoke the rebalance command to make this happen. This command is at the global context

level and causes the clusters to be "moved back” to their preferred peer. Enter:

eqcli > rebalance

Testing Active/Active Failover

1. With A/A disabled, verify that Active/Passive failover works the same as it currently does.

2. With A/A enabled:

a. Configure more than 1 cluster, but all in the same Failover Group and verify that failover

works the same as with an Active/Passive setup. Perform this with preferred_peer not set on

the clusters, and then set and verify that the clusters are instantiated on the appropriate Peer

and that they "failed over" as expected.

b. Configure one or more clusters on each subnet, setting a different preferred_peer for each

Failover Group. Verify that the clusters are instantiated on the appropriate Peer and that they

"fail over" as expected.

c. Using multiple failover groups, configure servers for the clusters, using both spoof and non-

Spoof.

l For non-spoof, configure servers on a different subnet than the cluster.

l For spoof, configure servers on a different subnet than the cluster.

d. Using multiple Failover Groups, change the configuration such that 2 Failover groups will be

merged and verify that all work as expected. For example, suppose there are 2 F/O Groups:

l F/O Group 1 -has subnet 172.16.0/24 with cluster cl01 (172.16.0.211), server sv01
