debug mode.
At the command line, type the following:
export LAX_DEBUG=true

10.5 High Availability: Running iManager in a
Clustered Environment
Although iManager is a session-based tool that ships without any failover features, you can run it in
a clustered environment. For more information about clustering, see the
documentation (http://www.novell.com/documentation/oes/cluster-services.html#cluster-services).
1 Install and configure iManager on the nodes in the cluster where the virtual IP is moved to (that
is, an Active/Active cluster).
If the node running iManager fails, Novell Cluster Services
moves (reloads) the virtual IP address on another node in the cluster.
2 Using the Generic_IP_Service template that ships with Novell Cluster Services, create a new
cluster resource called iManager.
This cluster resource uses a virtual IP address that moves between nodes in the cluster. When
creating a new cluster resource, the wizard steps you through the creation of a load script and
an unload script.
3 Verify the load and unload scripts.
The load script should contain only the following lines (any other lines should be commented
out):
. /opt/novell/ncs/lib/ncsfuncs
exit_on_error add_secondary_ipaddress xxx.xxx.xxx.xxx
exit 0
The unload script should contain only the following lines (any other lines should be
commented out):
. /opt/novell/ncs/lib/ncsfuncs
ignore_error del_secondary_ipaddress xxx.xxx.xxx.xxx
exit 0
