Failover

For "N+1" failover:

1. Each peer should have the A/A (active-active) flag enabled

2. The modes displayed will be different for active-active, as explained below.

As cables are removed, re-attached, and systems rebooted, the F/O Mode displayed for each peer will move

through the following failover mode variations:

Primary

The peer has instantiated allcluster IP addresses, and allsubnet failover IP addresses.

Heartbeating is working properly.

Mixed

The peer has instantiated some of the cluster IP addresses in the configuration and is

available as a Backup for others. It has also instantiated allsubnet failover IP

addresses for the subnets required by the instantiated clusters.

Backup

The peer has not instantiated any clusters and is available as a Backup. Heartbeating

is working properly.

Isolated

The peer appearsto be up but we cannot heartbeat it. Thisusuallyoccurs when a peer

is rebooted and has not yet fully assumed a failover mode, or when there is a

connectivity issue on a heartbeating subnet.

Unknown

The peer status is unknown. No heartbeats from thissystem have been received. This

usuallyoccurs when first configuring failover, before allpeers have started

heartbeating one another, or when rebooting a peer.

Standalone

The peer isnot participating in failover. It will instantiate allcluster IP addresses and all

subnet failover IP addresses that exist in the configuration file.

For detailed output regarding hearbeat status between this peer and other peers in the failover set of Equalizers,

specify the name of a remote peer:
