If not healthy
Verify that all members of the cluster have
sufficient bandwidth to handle requests. If a
cluster member is going down, the problem
resolves itself as other members of the cluster
are informed that the member is down.
If a cluster member is slow because it doesn't
have enough physical resources (speed or
memory) to handle the load, upgrade the
hardware.
Restart the Access Gateway. See
"Restarting the Access Gateway Appliance," on
page 80.
Modify the Identity Server configuration and add
an Identity Server. See "Assigning an Identity
Server to a Cluster Configuration" in the
