Failover
Displaying Cluster Status
Specify the name of a cluster to the show cluster command to see if the cluster is currently
instantiated on the Equalizer to which you are logged in. The first couple of lines in the output
indicate the cluster status, as in this example:
eqcli >
show cluster clB
This cluster has a problem:
Cluster is not active on this Equalizer
L7 Cluster Name : clB
Protocol : http
IP Address : 192.168.0.161
Port : 80
Preferred Peer : Eq-B
VID : 3
...
The second line of output indicates that this cluster is not instantiated on this Equalizer; if this
message does not appear, then the cluster should be instantiated on this Equalizer (assuming that
there are no other issues, such as a cluster mis-configuration that is not related to failover).
Also shown in the output are the preferred peer and
VID
(VLAN ID) settings. Basic troubleshooting
for failover includes verifying that all preferred peer and
VID
settings on clusters are correct.
Rebalancing
Rebalancing is usually done after a failover event occurs and all system have been returned to
normal service. This instantiates each cluster (and its required objects, such as servers) on the
peer set in the cluster’s
preferred_peer
parameter. In the example configurations that follow,
the clusters
clA
and
clB
will continue to run on Eq-A until you run this command on Eq-A:
eqcli > rebalance
This instantiates each cluster on the preferred peer set in its configuration. In this case, cluster
clB will migrate from Eq-A to run on Eq-B (its preferred peer) instead. The clusters will continue to
run on their preferred peers until a failover event occurs.
After rebalancing, the
F/O Mode
displayed for Eq-A and Eq-B should be
Mixed
. This indicates that
it is acting as the primary system for some clusters and as backup for others.
