Failover
Monitoring N+1 Failover
There are several CLI commands you can use to monitor failover status:
Displaying Failover Group Status
Failover groups are configured by Equalizer automatically according to your network topology and
the subnets on which cluster and server IP addresses reside. You can modify the failover group
configuration only by modifying your cluster IP addresses, server IP addresses, and subnet
configuration.
To display the current list of failover groups, use the
show fogrp
global context command:
eqcli > show fogrp
F/O Group Name F/O Group ID F/O Mode Primary Peer
Unassigned 0 Not Used
fo_group1 1 Primary Eq-A
fo_group2 2 Backup Eq-B
The four columns contain the following details information:
F/O Group Name
These are determined by Equalizer, according to cluster IP addresses,
server IP addresses, and the network configuration. ‘Unassigned’ is the
failover group used when active-active failover is not yet enabled. Failover
groups are not used in active-passive failover configurations.
F/O Group ID
An identifying number for the failover group. This is set by Equalizer and
not direcetly modifiable.
F/O Mode
Indicates whether the system on which you executed the command is the
current Primary for this failover group, or whether the system is a Backup
for this failover group. If a system is the Primary for this group, it
instantiates all the cluster IP addresses and failover IP addresses
necessary for the failover group.
Primary Peer
Shows the peer name of the Equalizer that is currently Primary for this
failover group.
