Logical load balancer ID, located on the on the Services
tab. To view the ID, select a service and click Details, then
select the Load Balance tab
-g http-group Name of the group to be added to the load balancer. This
is an arbitrary name specified by an administrator for easy
recognition
-P http Type of protocol the application service will use
-a 10.1.100.10 IP address to be used for incoming requests
-p 80 Port on which the load balancer listens
-H example-host.com Host name of the application service to be load balanced
-U "/" URI path of the service to be load balanced. Specifying “/”
(the root path) does not restrict access. To restrict access,
specify a path such as “/mystore”. In this case, a request
to http://host/ will not succeed, but a request to
http://host/mystore/mydepartment will succeed
-t 6000 Session timeout, in seconds
-O JSESSIONID Name or ID of an http(s) cookie to store session information
-u administrator user name for the ioexec CLI
NOTE: The SSL certificate for an https create load balancer group request must be
an X.509 certificate in DER format, with the private key included. The administrator generates this
certificate and ensures that it is signed:
F5 SSL Certificate
Adding and removing group members from a logical load balancer group
After deploying a service and creating a logical load balancer group, IO administrators can use
the following ioexec commands to add and remove servers from a logical load balancer group.

In the following examples, the ioexec addgroupmember logicalloadbalancer command
adds one server to the load balancer. The options are similar to the options in the creategroup
command, except for the IP address (–a option). Note that each addgroupmember command
specifies a different IP address.
A logical load balancer group should have at least two members.
C:\> ioexec addgroupmember logicalloadbalancer -s example-io-service
-l LogicalLoadBalancer:00000000-0000-0000-0000-000000000000 -g http-group
-a 192.168.200.10 -p 8080 -u administrator
C:\> ioexec addgroupmember logicalloadbalancer -s example-io-service
-l LogicalLoadBalancer:00000000-0000-0000-0000-000000000000 -g http-group
-a 192.168.200.20 -p 8080 -u administrator
Following is an example of removing a logical load balancer from a group.
